Dr. Molly Valli, DMD Dentist in Groton
General Dentist

Dr. Molly Valli

Dr. Molly is known for her gentle touch and her ability to make even the most nervous dental patient feel comfortable. She entered the dental field at the age of 15, assisting in an orthodontic office, and always knew she wanted to be a dentist because it combined her natural interest in math/science with the ability to work with people and fix things using her hands.

Dr. Molly is originally from Windham, NH. She earned her undergraduate degree from St. Michael’s College in VT and received her DMD from the University of Pittsburgh in 2013. This is also where Dr. Molly met Dr. Marc! Following dental school, Dr. Molly completed a general practice residency at Loyola University Medical Center in Chicago, where she received further training in all aspects of general dentistry. Dr. Molly enjoys getting to know her patients and working with them to select the best treatment options to improve their overall oral health.

The Vallis have two young boys, Jack and Logan. They love spending time as a family doing outdoor activities such as hiking, biking, and skiing. In her spare time, Dr. Molly can be found in the kitchen baking something delicious, usually while listening to an audiobook!
