Patient Ratings

Dr. Kellis is always willing to listen, answer all questions, give advice for treatment and rehabilitation.

I was experiencing unbearable sciatica pain in my left leg. Even though Dr. Kellis had an extremely busy schedule, he was able to squeeze me in for my appointment, another MRI and my much-needed operation. He performed a Discectomy on my L5 that was severely pressing on my nerve root. I had immediate relief from my sciatica. His bed side manner and promptness were exceptionally great! I am very glad that I chose him and his practice to fix my issue.– Brian

Dr. George Kellis has performed 2 (actually 3 major back and neck surgeries if you count the cyst removal ) all with in 2 months. I had my neck surgery in Feb. 2022 was recovering from that when a large cyst on my spine turned into somewhat of an emergency situation. Dr. Kellis removed the cyst and performed a spinal fusion of L4 -L5 – S1 in the same surgery on April 11, 2022. Dr. Kellis is not only an amazing surgeon he also truly cares. I was in excruciating pain and Dr. Kellis listened with compassion, answered all of my questions , and continually monitors my progress. I want to thank Dr. Kellis for all of the help in getting me on my feet again(literally).– John

Dr. George Kellis is a terrific doctor. I have been seeing him for over 3 years.My first surgery was a spinal fusion about 3 years ago and everything went fantastic. In August and November of 2021, I had both knees replaced. Again, a super well-done job. Dr. Kellis is very personable and caring physician who listens to your problems and concerns. I would definitely see him again if I need any orthopedic care. I highly recommend him as a physician!– Pam
