Dr Pirkle is everything I would want in an internist: exacting, accurate, kind and current. My medical care has been a team sport. Dr Pirkle has lead and formed that team. I have never been disappointed in a specialist Dr Pirkle has recommended. I believe quality medical care all starts and ends with an excellent internist, otherwise there is no cohesion. I highly recommend Dr Ross Pirkle.

-Bill C.

What I love about Dr Pirkle is that he takes the time to understand the problem. I never feel rushed. He is thorough and caring and provides reminders about getting vaccines and other tests with other Specialists. The staff is friendly and responsive and will get you an appt quickly if necessary. So glad I switched to his practice!

-Therese W.

My experience with Dr. Pirkle has been excellent. It was recommended that I see him many years ago. He persisted with testing until the problem was diagnosed and the solutions found. He did some extra work on the treatment of this unusual (at the time) disease and sent lots of info to me to help with the dietary treatment. Since then he has been supportive and available to me in the hospital and the office. I highly recommend him to anyone.

-Ellen P.

The office staff puts one at ease with their friendliness. Maricela, the medical asst. is above reproach and then, best of all is Dr Bernens, who doesn’t leave a “stone unturned”! He’s the best! If you want to be well or need to “get well”, he IS the doctor! Kind, gentle and caring. My family loves him!
