About Dr. French

John F. French, Jr., D.M.D.

Dr. John French earned his Bachelor of Science degree in Biomedical Engineering from Boston University College of Engineering before attending the University of Pittsburgh School of Dental Medicine for his Doctorate of Dental Medicine degree. He completed a general practice residency at Lehigh Valley Hospital and will be pursuing his post-graduate education at the Las Vegas Institute for Advanced Dental Studies.

Dr. French has been practicing dentistry since 2003 and stays on the cutting-edge of the latest advancements in dentistry by maintaining memberships with such professional organizations as the American Dental Association, Academy of General Dentistry and the American Academy of Cosmetic Dentistry.

Dr. French’s family has been in Sag Harbor since the 1800s back when it was a whaling town. We maintain that history by having our office in a 1830s house complete with the original wide plank pine floors and the original plaster moldings.

He is active in the community and works with local schools to educate students on what dentists do and what they can expect during their visit. We believe by educating children early, we can alleviate any anxieties of dental fears that may exist.
