He cares and I'm going to have back surgery, not the injections I've received many times. I would not feel comfortable with anyone, except Drm Thomas Nasser. The doctors are a very knowledgeable. I have known Nasser since I began treatment. He has many years of experience. If you need many types of pain relief, all of the doctors are very knowledgeable. The office staff works well with them. I've had a few issues of my medicine not being sent or partial was sent, but it was immediately resolved by the supervisor who works in medications. Otherwise, I am very pleased. I'm actually looking forward to relief from surgery in 2 days. Thank you, AVORS! Everything has usually gonecwell.

I am puzzled by the bad reviews I have been reading, so I thought I should give a review about my own experience there. The radio frequency procedure helps me greatly with my back pain and mobility. It has allowed me to be more mobile and take daily walks, which I couldn't do before. I am so thankful for Dr. Grewal, Dr. Adolfo Salcido, Dr. Lika Rosette, and Dr.Kosla, not sure if I spelled them all correctly. They are always kind, helpful, caring, friendly, explain everything thoroughly so I understand everything, and provide excellent sedation during the procedure... I forgot the anesthesiologists name, but she is super kind. The nurses and staff are always nice as well. I can't think of any negative experience I have had, or witnessed while I was in the office. I would advise a person considering going to this office, to try it out and see if it is to their liking, and then make their decision on whether this doctor meets their needs and helps them.

I had a failed spinal fusion and was in so much pain and on so much pain meds that no other doctor in the A.V. would touch me. Then i went to dr. Nasser and put me on a pain pump. He didn't care how much he had to see me he told me as long as i didn't give up he would never give up on me. Today im on the road to recovery, light years from where i was and on 1/1000 of the pain meds i use to be on! There is no doubt in my mind if it were not for Dr. Nasser his wife and the other Doctor's and staff at AVORS medical i would not be alive today! Thanks Dr. Nasser i owe you one and then some! Not only is he a great doctor, hes my friend too! No matter how tuff it gets hang in there! There are still good people in this world like Dr. Nasser "The only thing necessary for the triumph of evil is for good men to do nothing." ― Edmund Burke.

So I would never recommend him ever in my life.
