Very courteous and respectful staff and endodontist. Took my mom here and it was a very good experience for a root canal. Dr. Lanctot explained things very well and his staff made sure she was comfortable.

This clinic rescued me when my tooth was broken by another dentist probing a crack in my tooth. I needed to be seen emergently and the doctor did not hesitate to see me even though he had a full clinic and had to reschedule his patients. His assistant and his secretary were also total angels. I was very grateful for my timely, efficient, and excellent care! This doctor is not all about the money but about patients which is far too rare these days! Highly recommend!

Dr. Lanctot and his staff provided provided prompt, caring, and excellent care. Dr. Lanctot carefully explained the procedures and what he would be happening. I knew what to expect. Throughout the procedures I felt reassured by his words and actions. My experience was excellent.

Dr. Lanctot, hygienist Candy, front desk Denise... Amazing team! Went in for root canal... First, no pain throughout the procedure, Dr. Lanctot provided very calm, relaxed atmosphere - I even dozed off a couple times! Confirmation x-ray showed treatment to bottom of root, very thorough. Great team, would highly recommend!
