Derek Andelloux, MD

Pediatrics, Primary Care
“My years in Africa volunteering with the Peace Corps taught me the importance of working for the community within which we live. I chose to become a primary care doctor so I could care for my own community. Being attentive and present for my patients, who are also my neighbors in a small New England community is its own reward.” Island Staff Member

Dr. Andelloux previously served in the Peace Corps from 1999 to 2001 as a health care volunteer in Senegal, West Africa. As an urban volunteer, he was the primary liaison between fellow health care volunteers in the Matam Region of Senegal and local governmental and non-governmental agencies. He spearheaded campaigns on polio vaccination, infant dehydration care, HIV/AIDS prevention, and malaria prevention. In addition, he took on side projects teaching English in local high schools and improving information technology utilization in local hospitals and clinics.

With his roots in Southeastern New England, Dr. Andelloux moved from Rhode Island to Nantucket in part to be closer to his family, and has purchased a home on the island with his partner Megan.

“We’ve been coming to Nantucket for 10 years,” Dr. Andelloux said. “We fell in love with the island, and not just in the summer, but also in the offseason when it’s quiet and peaceful. We will enjoy living here year-round.” Dr. Andelloux enjoys cooking and board games, and is looking forward to learning how to fish on Nantucket.
