Our Team

Dr. Marissa Ryan

Dr. Ryan has been practicing dentistry for over 20 years. After completing her B.S. in Biology magna cum laude at State University of New York, Oswego, and her Master’s in Molecular Biology from the University of California, Davis, Marissa went into research. However, a deep desire to pursue a profession that focused on caring for others drew her to dentistry and the Tufts University School of Dental Medicine, where she graduated summa cum laude and was the recipient of several awards, including the Tufts University Merit Scholarship and the Tufts University Award for Exceptional Chairside Manner. She was also elected to Omicron Kappa Upsilon, the National Dental Honor Society, and is a member of Sigma XI, the National Research Honor Society.

Dr. Ryan’s professional memberships include the American Dental Association, Maine Dental Association, Pankey Institute, and Casco Bay Study Club, an affiliate of the Seattle Study Club. She has been involved in dental mission trips to Guatemala and has worked for several years as a volunteer dentist at the Root Cellar Dental Clinic in Portland. Her pride and joy in her life are her two amazing daughters, Julia and Natalie. She, and her husband, Bill, love to travel, taking the girls everywhere with them. They enjoy everything about Maine, from skiing to surfing to hiking. They consider themselves incredibly lucky to call the state of Maine their home.
