Dr. Peter Phan

I am a New Jersey boy who moved to Boston to attend Tufts University School of Dental Medicine after receiving my Cell Biology & Neuroscience and Economics degrees from Rutgers University. I thought I would end up back in New Jersey to take over my childhood dentist’s practice, but my plans took a turn for the best when I decided to stay in Massachusetts and pursue a newfound love of orthodontics. I completed my training at Tufts University Department of Orthodontics and Dentofacial Orthopedics in 2011.


Early in my orthodontic career I was invited back to Tufts to serve as part-time faculty. However, I had to give up teaching when life pulled me into private practice full time after my wife and I added two rambunctious daughters to our dog loving, beach loving, travel loving, and food loving family. I look forward to meeting all the South Shore Orthodontics families and taking care of all your orthodontic needs.
