About Your Dentist

William Harriett, DMD

The mouth has been referred to as 'the barometer of the body.' As we have seen from research in the past few years, this is a very true statement. Of course, our primary purpose is to address the dental and periodontal needs of our patients. However, we are in a unique position to identify other potentially serious conditions and refer for evaluation and treatment. It is truly an exciting and challenging profession.

My Mission

Utilizing the latest technological advances, we provide the full spectrum of dental care for our patients in a comfortable and caring environment. From root canals to extractions, implants to same-day crowns, ages 5 to 95, we do it all. Our team is truly excited to face each new day and the challenges it presents. Dentistry is our passion.

Life & Hobbies

I have been blessed to be married to my best friend Jenny for 35 years, despite the fact that we have worked together every day. How she puts up with me 24/7, I will never know. We have a wonderful son, Christopher, 26, who we are incredibly proud of. We both enjoy anything to do with water, jet skiing, kayaking, scuba diving, surfing, paddle boarding, and fishing. You name it, we do it. We also enjoy giving back to our communities by utilizing our God-given talents to serve others through mission work in Haiti, as well as the Good Samaritan Wildflower Clinic here in St. Augustine.
