We strive to help each patient develop a clear understanding of their oral health and the importance it has on their overall health.  Treatment plans are specially tailored for each patient as it is important to us that each patient fully understands their treatment options both clinically and financially.

Curtis Thibeault, DMD

Dr. Curtis Thibeault completed his education at the University of New England College of Dental Medicine.  He graduated among the top in his class while being inducted into the Omicron Kappa Upsilon Honor Society based on high scholarship and character. In 2018, Dr. Thibeault also received the Clinical Excellence Award for his distinguished clinical skills throughout dental school. He began his dental career here in NH in a private practice setting at Alliance for Dental care providing dental care for the greater Rochester Area.

Eager to achieve his dream of owning a dental practice, he was fortunate to meet Dr. Manuel Posada and his truly remarkable dental team. Although Dr. Posada is moving on to the next chapter in his career, Dr. Thibeault and our team here at Alton Bay Dental will continue to provide exceptional care tailored to each individual patient’s needs in a comfortable and calm environment.

Dr. Thibeault is thoroughly passionate about the art of dentistry and he along with his wife, Jayne and daughter, Aubrey are beyond grateful and eager to be joining the Alton community.
