From the moment my husband and I walked in the door until we walked out was an absolute JOY! Such a warm caring staff who acted as if we were friends not staff and patient. And Dr Rupp... GOD SENT! He doesn't talk AT YOU. He speaks WITH YOU. He doesn't use jargon to confuse you. He uses everyday examples on how to explain your ailments. Such a calm gentle spirit! THANK YOU FOR AN AMAZING VISIT! Worth the 2hr drive!

This was my first visit and it was fantastic. The doctor and all the student residents were very friendly and informative. They made it a point to treat me like a human and not just a patient. The assistant I had was phenomenal. Definitely recommend this office for anyone looking!

The best experience I've ever had with any specialist. The receptionist, nurse, and Dr. Russell are absolutely amazing in their professions and as people. I honestly can't say enough about how appreciative I am for all they did for me. I would recommend them to anyone.
