I cannot express enough gratitude to Dr. O’Donovan’s team at University Pain and Spine Center for the outstanding care and support they provided me during my medical journey. Their professionalism, kindness, and dedication to patient care were truly exceptional. Ari and Rachel, in particular, went above and beyond to ensure I felt supported every step of the way. They consistently followed up with me, checked in on my progress, and offered invaluable assistance with administrative needs surrounding my surgeries. Navigating medical concerns can often feel overwhelming, but their thoughtful and attentive approach made the process so much smoother.

Amazing interaction with Dr. Demesmin as always. Everything explained and all questions answered. Felt very relaxed speaking with doctor. 12-20-23 Had spine injections today by Dr Demesmin. Very quick and very little discomfort. Tech assisting was very helpful and friendly. Excellent experience considering what had to be done. 2-26-24 First time meeting Dr O’Donovan. Very nice person and very professional. He and his tech assistant explained everything about the first in a series of three knee injections. I even watched on x-ray the needle going into the knee joint which I wanted to see. Would definitely recommend Dr. O’Dovovan. Great person.

Every one were really pleasant and kind, Especially dr O’ and they were fast as well! They could have gotten me out of there sooner had it not been b’cuz of Lorraine Cadena who was too busy to see me but had me waiting. she had set up the appointment and I knew she works in the office. I just wanted to see her and say hello and thank you that’s all. It made me wonder why she refused to talk to me even though she set up the appointment. Everything else were perfect! Thank you so much everyone! Serena M. Walker

I was in tremendous pain from the symptoms of Occipital Neuralgia. I made an appointment with the office and they scheduled me for the first available appointment 1 month away. My symptoms became extreme before my appointment date so I called and they let me come in that same day and stayed late to help me before my appointment. The staff and Dr. Demesmin truly care. So Refreshing!! Highly recommend!!!

I've been bothered with pain in several areas of my body as a result of an accident (downhill skiing) many years ago. He has successfully treated many areas of my body; back shoulder, hands, knees. He has helped relieve pain when other doctors have been unsuccessful. Even when I moved out of the area, I continue traveling back to see Dr. Demesmin. He listens and tries varios modalities when one doesn't work. I highly recommend him.
