My daughter, husband and I have been going to Dr. Grondin for years, not only for colonoscopies but for other related problems. I get very nervous going to doctors but not with her. She makes me feel so comfortable and at ease. You feel as if you were visiting a friend. She never rushes and answers all questions. I would never want to go to someone else.

I have had to have 3 colonoscopy's over the years and have had Dr Grondin every time. In my opinion she is fantastic, answers all questions and takes the time to make you feel comfortable about the procedure. My mother also has had Dr Grondin and is the one to recommend her to me. I wouldn't even think of going anywhere else to have these procedures done. She is the BEST!!

She is very thorough and professional but made me feel very relaxed about my procedure. We discussed my medical and family history and I found her to be very attentive and ask thoughtful questions. I very much appreciated her bedside manner before and after the procedure.
