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.

Dr. Massino is extremely knowledgeable but takes the time to get to know you as a patient, unlike some doctors who only spend a few minutes with patients. Would highly recommend and will be seeing him again.

I work in the medical field, and I can honestly say that Dr. Nassiri is amazing. I booked an appointment easily using the online system, got a confirmation within minutes, and experienced one of a kind care and attention from his staff, from start to finish. Dr. Nassiri is kind, attentive, and really understood my issue - being that is was somewhat unusual and complicated. We came up with a great treatment plan, and I'm looking forward to my upcoming visits. To add to this, I had a minimally urgent situation after hours, and his answering service assistant was so caring and considerate, and the Dr was also available within minutes of my call - I've never experienced this with any other practitioner. Truly a great practice, doctor, and staff.
