Douglas Delli Colli, DMD


Dr. Douglas Delli Colli grew up in a small town named Pepperell, MA just south of Nashua, NH. He graduated from the Univeristy of Massachusetts Amherst in 2005 with a B.S. in Microbiology, and then received his D.M.D. at Tufts University School of Dental Medicine in 2009. While studying at Tufts, he met his wife Dr. Nichol Penna. They were married in October of 2011.


Dr. Delli Colli is currently an active member in both the Maine Dental Association as well as the American Dental Association. He also is adjunct faculty at University of New England Dental Hygiene School as a clinical supervisor, working with 3rd year students in their last year of schooling.


Dr. Delli Colli is excited to be joining the Dunstan Dental team alongside his wife, and inlaws. He is currently transitioning into the practice part time.

When not in the office, Dr. Delli Colli likes to stay active. He likes all outdoor activities, especially fishing, skiing, jet skiing and four-wheeling. When at home, he loves listening to music and always looks forward to relaxing with his wife Dr. Nichol, watching a good movie.
