Grace Harriman, DDS

Education & Continuing Education

Advanced Training in General and Hospital Dentistry
Brookdale University Hospital – New York City, New York

Doctor of Dental Surgery (2011)
University of Michigan School of Dentistry – Ann Arbor, Michigan

During her academic journey, Dr. Harriman recognized the widespread lack of understanding and appreciation for dental health among individuals. This awareness has fueled her commitment to ensuring that her patients comprehend their conditions thoroughly. 

Her dedication to staying abreast of evolving dental materials and technologies underscores her motivation to deliver optimal clinical outcomes. Early in her career, Dr. Harriman recognized the demand for compassionate dentistry in communities. Exhibiting leadership, she successfully established a thriving dental office in Philadelphia, evolving it into a multi-specialist practice with eight employed dentists. Her ability to win the trust and hearts of patients garnered her a citation from the mayor of Philadelphia in 2018, and she subsequently earned a place on Philadelphia's Top Dentist list in 2019. 

While Dr. Grace Harriman enjoys all facets of dentistry, she particularly relishes addressing the complex restorative issues of patients who have long avoided dental care. As a certified Lumineers® and Snap-On Smile® provider, she brings her experience in cosmetic dentistry to enhance smiles. Advocating the mantra "Oral health is mental health," she believes in the intricate connection between the orofacial region and mental processes, emphasizing the impact of a healthy smile on emotional well-being.

Life & Hobbies

Dr. Grace Harriman is a native of Michigan. She met and married a true Mainer who comes from a long line of lobster fishermen in downeast Maine. She decided to transition out of the city and move to Maine where she now lives with two toddlers and her husband. In her free time, she enjoys watching her children doodle on paper and dance. She spends a significant amount of time in continuing education to stay up to date. She also provides consulting services to private practices to start-up, transition, or empower their practices. Dr. Harriman loves her new home state of Maine and is deeply interested in community initiatives that make Maine a better place for everyone.
