Our patients are our friends.
Your don’t have to be a friend to be our patient, but it helps.

Dr. Trevor Hartwell grew up on "a big island," not THE Big Island. His hometown of Grosse Ile, Michigan, which means “Big Island” in French, is located in the Detroit River. He began free diving as a child when he would drop tools off his small sailboat and need to dive to the lake bottom to retrieve them. These early experiences helped him develop free diving skills that allow him to dive past 140 feet and hold his breath for over five minutes. Following in his father’s footsteps, Dr. Hartwell attended the University of Michigan for both undergraduate and dental school. His father was part of a notable graduating class and was classmates with Dr. Frank Sayre, a prominent figure on the Big Island. Since moving to the island, Dr. Hartwell has enjoyed mentorship from both Dr. Sayre and his father. Dr. Hartwell’s wife, Sara, an accomplished real estate broker and BIC at Koa Realty, shares his love for family time. When not working, Trevor and Sara love taking their kids to the beach, where their boys are becoming adept swimmers, much to their delight.
