    I'm very fortunate to have Dr. Ronald Hartfelder as my GI specialist. He is understanding, kind, thorough, very detailed. He's an overall great doctor for other issues that are surrounded or possibly linked to GI issues, and he takes all the time necessary with his patients. I've known him for a number of years, and I'm very pleased that I'm still his patient. Even though he's moved on to other roles, he kept his basic patients, and I was fortunate enough to be one of them.

    He was very easy to talk with and looked at my records to see what other providers had done regarding my recent medical issues as well as current ones. We discussed the medications I currently use for abdominal pain, bloating, constipation and diarrhea issues and changed medication. He has always been a very thorough doctor and thinks aloud so you know his reasoning for medical decisions.

    Dr Hartfelder listened to all the issues I was having . I told him that he did my first colonoscopy and remembered I had a very prominent diverticulosis. I was very comfortable talking about my sensitive issues. He gave me a detailed plan to follow and scheduled a colonoscopy in the Fall.
