February 9, 2026Majlinda L.Verified patient
The doctor was very nice however I went for an exam and he didn't lay a single finger on me I felt like he could at least have pretended to examine me. He asked me questions and he typed in his computer. I just didn't feel like it was a personal caring visit with the doctor

Dr. Hartman actually listened to me and offered solutions to the problems I am having. I have found that others gastroenterologist have been dismissive and unhelpful. Dr. Hartman seems to actually want to help!

I wasn't sure about seeing a male gastoenterologist but he made me feel very comfortable. He was very attentative and asked many questions. His body language was not aimed at the computer but aimed at me. I would recommend him.

The doctor was very considerate, kind, and compassionate. He was a great listener. He heard all of my 20 symptoms and then went through them one by one to collect specific details about each symptom. He waited a few minutes for me to think of any questions.
