Great experience
The best doctor
Very knowledgeable, great listener answers all my questions takes his time and reviews all my labs even ones from other specialties and lets me know any concerns or positive results. Thank you
Dr Marcot is very thorough during his exams. He always has his patients best interest in mind when meeting with them.
Good
Dr. Marcotte is wonderful. He listens carefully, provides good information, and instills confidence. I know folks are busy, and I know my appointment was toward the end of the day. But I waited a full hour to see the doctor for five minutes. I had to take off of work, which makes that long of a wait frustrating. I know this is unavoidable, and I will try to schedule better in the future, but I wanted to give you a heads up.
Incredible doctor. He listened carefully to my very complex situation, synthesized everything, repeated back to me, and worked out a solution for recovery. I wish all my doctors were as fabulous.
All the staff and doctor were excellent. Listened to my questions and concerns and answered all my questions. They took their time to make sure I got checked in correctly and made the whole appointment run as smooth as possible.
