Dr. Nourian is the best. His bedside manner is friendly and professional and his staff is excellent. I went to see him after a terrible whiplash injury when I rear-ended while driving. After receiving my MRI results, the doctor was quick to reach out and went over my options with me. He really cares about his patients.

Michelle Sadighpour Shophet


Dr. Nourian is an outstanding physician. I injured my back while exercising recently. I went to see him, and he explained my injury to me in detail. He told me that my injury would most likely heal without surgery, but if I needed surgery in the future he would get me through it. He is honest, intelligent, and forthcoming. I am thankful for him as my spine physician.

Michael Broukhim


Dr. Nourian was absolutely fantastic. I was struggling with intense lower back pain. He took his time 40 minutes to be exact to see me and review everything with me after another follow up we decided to do surgery. Thank god!!! I’m back to working out, picking up my child, and living my best life. I was so hesitant to do surgery but he was a true god send. He would call me weekly to see how I’m doing.

After seeing three doctors and all of them saying I should operate Dr Nourian was able to address and issue without and surgery. I got an epidural and did physical therapy and I’m able to run around with my grand child. He’s truly a gem. Everyone at the office was friendly and supportive.

Dr. Nurian explained everything very well and preformed the surgery exactly as planned. I woke up pain free and the surgery pain was gone in five days. Could not give him enough praise.
