Dr. Nassiri is a real professional. He is a throw back to simpler times. He is always available for questions and when you have an appointment, with him, he will give you all the time you need. He is the 3rd doctor to give me an Epidural and the first one to give me the relief from pain I hopped for.

I was referred to Dr Nassiri from my back surgeon to R/O having low back surgery.I have been to several Pain Specialist over 25 yrs due to failed low back surgery.Dr Nassiri listen to me and after a few minutes he said, I will do my best to get you some relief from my pain. It has only been 6 months or so and I have such a great quality of life. Thank You so much.

I am a 78 year old medically retired physician (psychiatrist) suffering from chronic pain and physical limitations caused by chronic neurologic and orthopedic conditions. Dr. Nassiri has the knowledge, empathy, patience and compassion that are greatly appreciated by me in my struggle to deal with my chronic problems. I am comforted to know that he is always there for me just like I used to be available for my patients.
