Dr. Toumbis is amazing. The entire staff is totally awesome from Alan, Brittany who are so professional and know what they are doing. They work hard to find out the problem and solve it. Dr. Toumbis is the BEST doctor. He spends time with you and allows you to come to a decision once he has the entire picture. Dr. Toumbis did my neck surgery, the most painless surgery there is. Dr. Toumbis will be my ONLY surgeon, he is amazing.

I am very satisfied with my care, surgery, and the care and compassion from Dr. Toumbis and his staff. I would HIGHLY recommend his office and surgeon to anyone.


Always a wonderful experience even though I'm not there for the best of reasons. Dr Toumbis and everyone on his staff are very kind, caring and professional. I moved out of the area but came back in town just to see Dr Toumbis. I don't trust anyone else. He's the best.


Dr. Toumbis has followed my bulging lumbar disc for 4 years. He has prescribed conservative therapy. Often one hears that spinal surgeons too readily prescribe surgery, not Dr. Toumbis. He explains what is going on with my back, what will help, and to return if symptoms worsen or change. I always feel comfortable with his care when I leave. I always am treated with respect and courtesy from him and his office staff. The facility is very clean and wait times are minimal.
