Thomas Backus


Dr. Backus grew up in the Vancouver/Portland area, went to Clark college and WSU-Vancouver to obtain my bachelor’s in biology degree. Then, he completed dental school at UW school of dentistry in 2018 with 2 awards in touring/mentoring dental education. After four years of practicing in community health dentistry, he joined the team at Austin Family Dentistry in 2022.

Dental school and working at community health clinics taught Dr. Backus the knowledge alone in not enough to complete the procedures that are performed on the patients. Not only is precise knowledge of the procedures required, but coordination and, above all, a lot of patience.

He choose a career in dentistry for intellectual challenge, opportunities for service, and the chance to make a concrete difference in each patient’s life in a way that will positively impact their health and their self-esteem for years to come.

Hobbies include martial arts, cooking and on a small hikes.
