Meet Our Dentist

“I grew up in the Lakes Region vacationing with my family. My passion for dentistry began in high school, when a local dentist gave me my first job. I still enjoy dentistry and my patients today as much as I did when I started out.”

Dr. Dori graduated magna cum laude and is a member of both the Omicron Delta Upsilon Dental Honor Society and Gorgas Dental Honor Society. She has continued her advanced training and development through many, many hours of post-graduate studies annually, in topics including:

  • Comprehensive Treatment

  • Implant dentistry

  • Braces & Invisalign

  • Dentures, partials, crowns & bridges

  • Botox


Throughout her career, Dr. Dori continues to study various aspects of dentistry, focusing much of her effort on orthodontics for the general dentist, other advanced dental procedures, and high-tech dentistry. She is a current member of the American Dental Association, New Hampshire Society.
