Patient Reviews

Helped my wife’s sore knee when another doctor was unable to offer relief. Empathetic and knowledgeable.

-Gary Johnson

Dr. Eggert is thorough and listens to the patient experience. He explains his considerations during his assessment. So glad I went to him for a second opinion after recalling my daughter also received great care from him a few years ago.
