Meet Our Team


Jill Harrison, DMD

After practicing in the Portsmouth area for several years, Dr. Harrison established Harrison Dental Arts so that she could better serve the Seacoast community. Her philosophy is to treat patients how she would treat members of her own family and aims to build relationships built on mutual trust. She encourages patients to become involved in their care, strives to provide patients with all their options, and works with patients to determine a treatment plan that is the best fit for each individual patient.

As a testament to the quality of her work, Dr. Harrison was voted one of NH’s top dentists in 2018 and 19 by her peers at New Hampshire Magazine.
