  • Dr.
    Holly Clark

    Dr. Holly Clark was born and raised in Baton Rouge, Louisiana. Her given name is Hollis Anne Clark, however she has always gone by Holly. She is named after her late grandfather, Dr. Hollis Gamble. He was a dentist in Mansfield, Louisiana. He taught her at a young age that dentistry is a wonderful career, and if you devote yourself to it, you can help a lot of people.

    Dr. Holly received her Bachelors of Science from Centenary College of Louisiana, where she studied biology and played college tennis. It was somewhat of a “home away from home” because her grandparents lived in Shreveport at the time as well. After realizing that dentistry was her true passion, she was off to New Orleans to the LSU School of Dentistry to obtain her Doctorate of Dental Surgery. She graduated top of her class and won many awards during her time in dental school for academic and clinical excellence.

    She is still an avid tennis player and is involved in many tennis leagues in town. Her other hobby is that she loves to travel. She’s visited over 30 countries! Though, with a new practice under her belt, she might be slowing down on jet setting.

    Dr. Holly takes her time getting to know her patients and treats them with compassion, as if they are her own family. We are excited she’s apart of our work family now, and we can’t wait for you to meet her!
