Nurse Practitioner Callie Hart is practical, smart, knowledgeable, compassionate, and careful. She listens well, has very good judgment about what will work for (or be tolerated by) the patient. We have great confidence in her.

It is always a great experience, start to finish. The wait time is reasonable. Jonathon Thelen, the PA I see, is EXCELLENT. That guy gets it done and done well. He is always friendly and makes good small talk while dealing with the biz of my twice-yearly check-ins.

I’ve been a patient of Dr. Albert Ross’s for a number of years and he has my complete confidence to care for my GI health. A great communicator with years of experience, a true professional. Thank you!!

My experience at DHI had always been excellent. We are always greeted & welcomed immediately upon arrival. All caregivers & physicians have met or exceeded our expectations - Scott in particular is very thorough and explains thoroughly in a way that we understand. We highly recommend DHI.

I have been going to Michigan Gastroenterology since the early 90s. My doctor is still there. All staff is easy to talk to and they respond to questions and concerns well. The PA Scott is wonderful to work with.
