Patient Reviews

Dr Eggert, I feel, did an excellent replacement on both of my knees. He has aways been easy to talk to and has always been responsive to all my questions and concerns. I’d strongly recommend him to anyone needing knee replacement therapy.

-Steve E.

Dr. Eggert is very easy to talk to and always explains and answers your questions and concerns that you may have. Did a super job on my left knee replacement and I will have my right knee replacement in a couple of weeks. Thank You.
