“There is much more to pain management than medications and injections. Pain management does not live as its own entity like most people think. Pain management is actually an integral piece of rehabilitation. So numbing the pain is not the answer, improving the pain to allow patients to do their daily functions is really the answer. And that’s what I do as a Physiatrist.”

Thomas S. Nasser, D.O.

Dr. Thomas S. Nasser is a Doctor of Osteopathic Medicine (DO), Board Certified in Physical Medicine & Rehabilitation (PM&R), and highly-rated in Pain Management. He is currently one of two AVORS Pain Management physicians in the entire Antelope Valley making regular hospital and nursing home rounds.


An Osteopathic Doctor Taking a Comprehensive Approach


Dr. Nasser is specially-trained as a Physiatrist who treats injuries and illnesses, both of which have the potential to affect how you move, compromising activities of daily living. Treatment focuses on nerves, muscles, and bones. He’s also an expert at diagnosing and treating pain and/or dysfunction with the objective of restoring maximum health and quality of life to patients of all ages, whether they have difficulty functioning at home, at school, in the workplace, or during recreational activities.


One of Few Physical Medicine and Rehabilitation (PM&R) Physicians


As one of only a few Physiatrists in the area, Dr. Nasser brings passion, energy, and a fresh approach to the treatment of:


  • Brain and Spinal Cord Injury Rehabilitation
  • Post-Stroke Rehabilitation
  • Pain Management
  • Amputee Care
  • Orthopedic-Musculoskeletal Problems
  • Sports Medicine
  • Work Related Injuries
  • Arthritis
  • Neck and Back Pain


He focuses on the development of a comprehensive program for putting the pieces of the patient’s life back together after injury or disease, avoiding surgery whenever possible, providing the most conservative treatment possible.

Dr. Nasser is certified to perform a variety of procedures, including:



Dr. Nasser utilizes a comprehensive approach — with the primary focus being the patient — to determine his diagnosis.


“The most important consideration is what the patient expresses/tells us — that’s essentially what we go off of,” Dr. Nasser says. But Dr. Nasser also takes into account what additional materials that shed light, such as labs, reports, electrodiagnostics, imaging studies, etc.


“We take care of people, not pictures.” ~ Dr. Nasser


Dr. Nasser then treats “the whole person” not just the symptoms. By evaluating the impact of a condition on the person as a whole (medically, socially, emotionally and vocationally), he helps his patients understand and take control of their health.


The U.S. Department of Health and Human Services has classified the abuse of opioid medications as a public health epidemic. Dr. Nasser is a licensed provider of Suboxone, a prescription medication used to treat adults who are addicted to opioids. He is committed to doing his part to end this crisis, and will work with you and your loved ones to develop a comprehensive treatment plan for opioid addiction.

Doctor of Osteopathic with World Class Credentials

Dr. Thomas S. Nasser graduated from medical school at Western University of Health Sciences in Pomona, California. He then traveled to Toledo, Ohio, to complete his residency in Physical Medicine & Rehabilitation (PM&R) at the Medical College of Ohio, where he served as Chief Resident.

They are so wonderful. They will help you.

--Vahlcanna N.

The waiting room is often busy but I guess that's because they are good like trying to get a reservation at a top restaurant . Once you get to see the doctor you realize it's worth the wait.

--Robbie P.

Dr. Thomas Nasser, is One of the most compassionate caring Drs., that has ever graced the earth, I am and have been, Truly Blessed, to be a long standing patient of his. He HAS ALWAYS BEEN a Human, Family Man and Friend, as well as a Doctor. The best kind of person at ANYONE'S side during the best and worst of the healing process. In 18+ years he is consistently, "CONSISTANT". He is always  concerned with me and my healing process, not just in "his" practices but he's always seen the "whole picture". All the time. Remembering the smallest of details. Never ever getting it wrong! He has ALWAYS been concerned with my health AND COMFORT. His staff is ALWAYS educated and compassionate. (There are other Dr s with staff in the office as well. Also, them are always kind and compassionate as well.)
Thank you DR. T. NASSER!!!! Thank you for all you have done for me and patients all over LA county and elsewhere! If you are looking for a Human as a Dr., this is the way to go! (Probably find other Dr.'s there at AVORS, as well!)

It is important to note;
The Staff has A LOT to deal with. They have had AMAZING people come and go through the 18+ years that I have been with Dr T. Nasser. They keep the good ones. Others find that they don't want to stay. But ALL OF THEM have a Tremendous amount people that they encounter- every single day.  So try to remember that these people are putting themselves in harms way, every single day they go to work. Also keep im mind that these people are; Mothers/fathers/sisters/brothers..... Compassion always wins At Dr Nassers Clinique.


--Charlie G.

If u r having any issues w mobility n pain Dr. Nasser is the best. I was completely paralyzed n they didn't expect me to ever walk again. Dr. Nasser got me immediately in PT n I have been walking ever since. He helped w everything I needed to get thru all the tough stuff. He's the best Dr. n if he can't help w something he'll get u to someone who can.


--Claudia L.

I have been a patient at AVORS clinic for about 6 years. I started with one physician, who left to start a private practice. I then became a patient of Dr. Thomas Nasser, who was a really great health care provider. Eventually his practice became very busy, so I started seeing Dr. Orlando Pena. I have been really impressed with both Dr. Nasser and Dr. Pena. I recommend AVORS clinic for pain management, orthopedic surgery and hand specialty.


--Kathleen D.

Only wish I had known that the Doctors and the staff were so helpful and recently gave me a choice to end my back pain!! Soon this will become permanent and I wish it were today! Thanks all!!

--Amelia B.

I have seen both Dr Pena and Dr. Thomas Nasser for pain relief issues. Besides previous issues with my back being fused together, I also have knee problems. These doctors really care.  They pay attention to what I have to say and have helped me through some very difficult times. You can tell they really care.  Pain management isn't an issue anymore. Thank you for all the help. They are amazing!

--Barb C.

My experience was as follows, so I want to say thank you to the Check In Counter staff. Even though they were so busy they still kept an observant eye on the waiting room and took notice of my behavior and asked me if I needed help checking in, I did.I brought a book to read anticipating a long wait time to see the doctor, which didn't happen. Thank you for seeing me on time.

Thank you to Dr. Nasser and his assistant. During my exam and at the last minute, I asked for an injection that wasn't on his To Do List and they gave it RIGHT THEN, RIGHT THERE. After my exam I stopped at the Appointment Desk and was taken care of by an angel. She showed to me genuine concern asking if I was ok because she saw I was rubbing my wrist at the injection site. She booked my routine telemed appointments for the next three months. Then took the time to help me use the borrowed cell phone I had and dial my ride home for me, I'll learn to use one someday. THANK YOU AVORS Medical Group!


--Pam H.


I have been going to Dr Nasser for about 10 years now. And he has found reasons for my pain. That no one else even looked for. He has been great keeping me on the medication I need. Without any problems
And his staff are all friendly and helpful. Always there to help. I wouldn't change doctors unless I moved out of the area. I would recommend anyone having pain. To give Dr Nasser a chance to help you. He is a great Doctor.


--Donna G.

The staff and outstanding medical professionals are more than simply a cut above. I've used the massage therapist for severe pain issues, and been more than satisfied with significant improvements. Doctor Thomas Nasser, and his Nurse Practitioner Maria Davis have been treating my wife for years. Excellent care both in the office visits, tending to any issues and even making hospital visits when necessary. Excellent relationship and very concerned about the patients. Just haven't seen medical care this good in many years.


--David G.

Excellent! Dr. Nasser always answers ALL my questions and staff is very efficient, and big thanks to Vanessa


--Teresa O.

Dr. Thomas Nasser is the best! He and his amazing team of professionals have always treated my elderly mother, Linda, with pure kindness and compassion. I thank everyone at AVORS for always going above and beyond.


--Nina P.

Doctor Nasser, the nurses and staff are all very kind and compassionate. They take care of my needs very quickly and take me very seriously. After 31 surgeries and continuous problems you can imagine that I have been to several Doctor's for pain management. I can tell you in all honesty AVORS is number 1 on my list.


--Deborah C.

Dr. Nasser is great. He is really trying to take care of my back pain without me having to go through a big back surgery. We are making progress. Yea!


--Carol F.

Professional staff, clean office, very knowledgeable doctor. Dr. Nasser is the best.


--Royce B.

Dr. Nasser is a top notch pain management physician. He’s caring and attentive, listens to everything concern, addresses every issue. You’d be crazy not to want to have this guy on your side for pain management!


--Aleesha V

I had a very good experience at this office. I saw Dr. Nasser who told me "I'm going to fix you!"  I believe he will. Everyone in the office is very helpful and professional. You do not have long wait times ,like you do in some offices. I do believe the Doctor truly cares about me.


--Barb C.

I appreciate the kindness I receive.
Dr. Nassar and his crew are so efficient.
I drive 8 hours round trip just to go to his office. The treatment I received is it.


--Arlet W.

I have been a patient of AVORS for about 5 years. I have seen three different physicians there. I can truly say I have always had great care with each doctor. The staff have always been very friendly, professional and helpful. I drive an hour and a half to get to the AVORS office and because of the great care I receive, I don't mind it at all, even with the increase in the cost of gas. I plan to continue being a patient there. I have been a regular patient of Dr. Thomas Nasser DO and now Dr. Orlando Pena. I think they both have a great bedside manner and are very caring health professionals. The clinic is very clean and neat also. A great place to receive your health care treatment.

--Kathleen D. 

Dr. Nasser is a wonderful man and doctor. Very professional and compassionate to every patient and staff. I recommend him to anyone and everyone experiencing pain. I've been with him since 2012. The new office is beautiful and the staff is top notch attentive to you every need. You can't go wrong with AVORS Medical group.


--Patricia C.


The staff and nurses at AVORS are extremely friendly and professional. Everyone there is very helpful and welcoming. Dr. Nasser is a great doctor. “The best!” I couldn’t ask for a better facility. I’m very pleased with the treatment that I receive at AVORS Medical. 💕


--Cindy F.

I was suffering greatly for the last 14 years. I was with another pain doctor and we made no headway, no improvement. Everyone is afraid of not just losing their job in the pain management biz but being charged as a drug dealer by the government. Dr Nasser and Dr Pena at AVORS saved me. I had a pain pump installed and now am beginning my new life. Really and truly. I was sitting around the house wasting away until I found AVORS. You don't have to suffer. Yes I am a real person and a real pain patient.


--Rich C.

I LOVE LOVE AVORS medical group. Dr. Nasser is the best!!  I won't go anywhere else.  Hes out of network for me but I won't see anyone but him. They are very clean, friendly, professional and they truly care. Could not ask for more.


--Tarra D.

I've been dealing for 9 months with a very painful injury. In 7 months the VA couldn't figure it out, but it only took Dr Nasser at AVORS a couple of weeks to figure out the nature of the injury and set me on the road to recovery. Thanks to AVORS, though I have a bit of a road ahead of me, I'm feeling much much better!


--Joshua M.

AVORS is the place to be whether you have a sprain, a fracture or dislocated  knee ;) In all seriousness...been with Dr. Nasser & Crew about 3 years now ...everyone from the front of the office to the back are always professional and pleasant. Dr. Nasser is AWESOME (highly recommend) he cares about his patients, as well as his staff, and it shows.


-Jack C.

I have been a patient of a voice medical group and Dr. Thomas Nasser for well over a decade.  I’m in person for suffers from end stage kidney failure for 14 years, anytime. I’ve got with several several doctors and I must say Dr. Nasser and his staff in fact all the staff at AVORS or 100% the nicest kindest, caring,staff Of medical professionals that I’ve ever come across. I highly suggest using this medical group as they are the best I have ever come across in my entire life


--Eric V.

They are the best. Dr Nasser found my problem and sent me to someone to try to fix it. And even after I saw a surgeon about my next and back. I went to him for 10 years for his help with my pain. He was a pleasure to have as a doctor. The only reason I even left him was I moved several states away. The office staff was always easy to work with they did everything in their power to help. And always with a smile on their face. I really am going to miss Dr Nasser now that I've moved.


--Donna G.

My family and I have utilized the amazing services of AVORS Medical Group for many years. Doctor Thomas Nasser (Physical/Pain Management) and NeuroMuscular Massage Therapist Marla Johnson are absolutely integral for maintaining a proper daily functioning routine. I can’t recommend them highly enough.


--David G.

I have been bringing my mom to Dr. Nasser for many years and despite a very busy practice has always made my mom and her care a priority. And the staff is absolutely amazing!


--Raquel P.

Amazing Group of Pain Management, Hand Surgeon & Orthopedic Surgeons!!! I have been seeing this office for 13+ years now and I’m extremely satisfied with the care and service!!! They have been providing me with the highest quality care and helping me with my carpal tunnel, cubital tunnel, and most recently 3 fractured bone    chips in 2 fingers (R Index x2 + R Middle x1) Dr. Heller is Amazing 😉!!!

Dr. Nasser is THE BEST PAIN MANAGEMENT Dr. I HAVE EVER BEEN TO and has been treating my Pain in my Neck Fusion with an Implanted Pain Rx Pump for over 6 Years but overall has been treating me for over a decade!!! Dr. Nasser is NOT LIKE “Pill Pusher Doctors” because he Truly Cares about helping people with pain feel better and live better lives through the watchful supervision of their unique pain management needs & Dr. Nasser is also NOT like some Dr.’s who don’t want to give people any pain meds because they are too over cautious about potential abuse issues, because Dr. Nasser is willing to do what he determines a patients needs are and use all available tools to help people live better lives through Actively Managed Pain Care!!!


--Zane D.

Dr Tom Nasser is great very caring always on top of everything if I could i would give him 100 stars 😁


--Silvia V.

The staff at AVORS is polite and helpful Dr. Nasser has been treating me since I was injured in the Army and medically retired. Dr. Nasser takes the time to explain my treatment plan and listen to my concerns about medication levels and type of medication.


--Anthony I.

I just recently started seeing Dr. Nasser again after a five yr absent when i went in his staff treated me like i hadn't been gone DR Nasser still treated me with respect and listen to me also answered all my question's I recommend If your having back problems to make an Appointment with his office.


--Andre V.

Dr Nassar is the real deal.  I travel almost 200 miles RT just to see him and only him when he’s available!


--Anna N.

It's been a long time since I've had a Dr that cares he is compassionate intelligent and easy to talk to as  Dr Nasser thank you from both of us.


--Mart M.

I heard about AVORS Medical  from a great friend of mine, who kept raving about this Dr. Nasser. I saw the difference in her from before and after Dr. Nasser and it was like night and day. I went and saw Dr. Nasser, within the first five minutes he had completely won me over. He actually encourages his patients to ask questions and he wants your feedback on what he has prescribed or ordered you to have done. The best thing is he actually remembers your medical history and problems from memory without looking at his paperwork or computer. Anyone who has to deal with doctors on a regular basis knows how rare that is and how comforting it is to not just be another face lost in the crowd. It is not just Dr. Nasser that is amazing, all the other doctors and every single staff member go above and beyond the normal  standard. I have also seen Dr. Pena, and he is great as well. He too listens and welcomes your questions and feedback. I have had to deal with more doctors than I can count but I have never seen the quality of doctors and staff members like I have at AVORS Medical. They are located at  42135 10th Street West, right next to the Social Security office. You will be more than happy and very satisfied with your experience there.


--Dana S.

I have been seeing Dr. Nasser for several years now and he always takes the time to listen to my concerns They always make me feel comfortable about anything that I have concerns about. The women are very warm and welcoming when you arrive. I’m always seen in a timely manner. Everyone associated with AVORS is very friendly and I would recommend them to anyone who is looking for an excellent Orthopedic Doctor.


--Jamie S.

They are a great company and all the doctors I’ve worked with in there are amazing. Very smart and upfront about what’s going on. I love the personality of all of the doctors and staff. You can tell they vet their staff well, and make sure it is a group of well educated employees. As for Dr. Tom Nasser, he’s been a saving grace for me mainly. Without him I’d be stuck in pain and he has fixed that without any strong pain meds!! Proud to go to AVORS!! They make you feel at home.


--Joey G.

I am so happy with every person of the staff, that I have dealt with. I have never had a bad experience. I love Dr. Nasser and Dr. Pena. They are both super nice and very knowledgeable.

The facility is always very clean. The waiting room is huge and comfortable. The doctors work very hard not to leave you in the room forever. I have only positive input for AVORS!


--Giulia S.

Great service. I’ve been with Dr. Nasser on and off for years. He has really mad life more bearable. Thanks all


--Octavia B.

All the Doctor's and staff are awesome! I'm honored to be a patient of Thomas Nasser who has helped me in my long battle with RA and Osteoarthritis. He has been able to give me facet blocks which has aided in pain relief. ☺


--Leigh B.

I have seen Dr Nasser for years and Maria many many times as well.  They are both kind, genuine, knowledgeable, and professional people.  They try to exhaust all options to relieve pain of course, but they also really listen to what’s going on with their patient’s health.  I really can’t express enough how much I have appreciated their efforts to help me to improve my health and lessen my pain.  Dr Nasser once started a sentence with “ If you were my mother I would...” and that meant a great deal to me.  He treated me as he would a family member.  That’s not common.   Anyone would be in great hands with either of them and their wonderful staff as well!!!


--Debbie H.

Ok first let me say that the staff at this place are over the top amazing. Second DR Nasser  oh my god we're do I start. I started going to avors because I couldn't get answers from the VA. I got a referral to avors. I'm a really picky person when it comes to drs. ( I have had really bad experiences in the past) my first day there DR Nasser walked in and had the biggest smile and the most soothing personality, never in my life have I had a dr that has been so intuitive and listens. I have been going to avors for 7 months now and I have found the best dr I could find it has truly been a blessing. I have answers I have been looking for finally after 5 years of no diagnosis. Dr Nasser is the real deal and I would recommend him any day. Don't hesitate to go see him he's a blessing and has changed my out look on my life. I finally have relief. Thank you avors and Dr Nasser


--Tracy L.

Dr Nasser is a good doctor and takes time to talk with me and make sure that I'm okay with each procedure and if I have any questions, he answers them. I've always had a good experience at avors oh, and I would recommend it to anyone!


Michelle C.

I have been going to AVORS medical group for the past year and a half the service is excellent i have been seen by Dr. Thomas Nasser who is extremely knowledgeable patient recently i needed a cortisone shot in both my knees i was terrified Dr. Nasser was quick and i did not feel anything.

--Darcelle A.

I love all the doctors under this roof. They know what they're doing, they want you on your way to wellness and they do everything they can to achieve that. I love doctor Nasser and his extensive diagnostic care he's given to me. I hope to have doctor Nasser for the rest of my time. He's given me a team of great providers and a level of care I've never really experienced anywhere else. I thank God for these people, frequently.


--Diana M.

As a new patient at AVORS, I am just learning about the many types of support provided to patients, including monthly appointments with Dr. Thomas Nasser,  collaboration with my neurosurgeon, having staff available to assist with scheduling, medications, and durable medical equipment, and the excellent Acute Rehabilitation Unit at Palmdale Regional  Medical Center. I really had no idea how all-encompassing AVORS is beforehand, and I greatly appreciate all of the assistance being given to me. Thank you!


--Anne G.

I have been going to AVORS Medical Group for over 10 years!  The staff is amazing.  Dr Nasser

--Debbie

Doctor Tommy is one of the best Doctors I've ever come to know..

His heart is kind and I truly believe he took his oath to help people.. I wish I could BBQ with him. Hes the kinda guy you wanna be friends with outside of his work.. 2 thumbs up for him 4 thumbs if you wear glasses .. lol.


--Wayne A.

My husband has been a patient of Dr. Nasser for more than 7 years after an amputation and terrible phantom pain. Dr. Nasser and his team have been compassionate, supportive, and have continued to explore options and give us hope. We can't tell you how important AVORS is to our entire family.


--Fox T.

This was my first visit at Dr. Nassar's facility.  The staff was professional and friendly.  They collected my information and I met with Dr. Nasser.  He we very helpful and I believe that this will be a good Doctor - Patient working relationship.

I have been going here for several years and Dr Nassar and his team are amazing people. If it was not for him I may not be here today. Thank you Dr Nassar and the entire AVROS team for always taking care of me. See you in 2 months!


--Steve M.

--Ashley C.

The very best care I have ever received has been with Dr. Nasser.
Takes the time to listen to me and address my concerns and explain to me what is going on in my case sometimes a little complicated.
They have gone over and above to contact me and check on me, I have never had any other office do that for me.
I really appreciate the doctor and staff there.
I feel like care about me and trust them.
Thank you all at Avors!


--Robbie.

I was referred to Dr. Thomas Nasser on Jan of 2015. Obviously because he is the "BEST" pain mgmt/sports rehabilitation/spine specialist. 🤩😁😉👍 Thank You Avors for providing "Top notch, impeccable, amazing, fantastic Service to mE! :-)


--Kimberely W.

AVORS is a fabulous place. The waiting time is about par for the course. Dr. Sherfey, my ortho, is the best, in my opinion, number one. I am seriously looking at "going under the knife", and am confident with Dr. Sherfey and his skills and also his explaining in detail and answering all the questions that I had.


--Phil D.

Dr Nasser is great. He was my mom's doctor. He now have become my wife and I doctor.


--Ryan W.

I have been seeing Dr. Thomas Nasser for 13 months, he is the best pain management Dr. I have ever had the pleasure of being a patient of,my doc, he is very special, he will go to any lengths to take care of you, His staff, all of them, are a very special group of young people, I say young people because they are all, extremely accommodating, every member of the AVORS staff, always have smiles on their faces, they go to great lengths to make sure that you are being cared for, from the rope at the front desk. to the young lady who asks you about your pain level, and how well your medicine is working, and rest assured that Dr. Nasser asks all the same questions, it's like there is no way way to miss something, the staff are extremely knowledgeable about pain medicine, and what works well with what, no stone goes uncovered, if these people don't have the answer they will get you the answer, quickly. I could go on and on, just 1 more example of how much Dr. Nasser cares, he talks to you not at you, Even during the worst of Covid, Dr. Nasser would put out his hand, shake your hands and smile, I came to Dr. Nasser, from a doctor, who was all about the money, not my Dr. Nasser, he's all about his patients, I have never seem him lose it with a patient, his smile truly warms the room. You be sure, your going to get the very best level of care, need him at night, just call, it might not be Nasser himself but the doctor cares just as much, he takes time with you, you never feel rushed, everyone in this group is splendid, the girls who make your appointments to the ones that call in your meds, rest assured you are in great hands, his impish smile, goes a long way with me, he puts so much time into the time, he, cares, really cares, he will go the extra 10 miles, he is just a true old fashioned Doctor, who lets you know he can be trusted, so give my doc a try,what do you have to lose, he's just awesome.

The whole team is without issue, they will take excellent care of you, go the extra mile

The best care I have ever received from a physician. He always takes the time to listen to me and my concerns /questions, he takes time to explain things to see me and give me options. I feel that Dr. Nasser and staff really care their efforts make a big difference to me. I feel comfortable and know I can trust him. I have been a patient here for many years I thank them for the great care always.
