Justin Cowan, DDS



As a dental healthcare professional, my patients are of the utmost importance to me. Their care, comfort, and smiles are my priority every day. I am constantly striving to increase my knowledge and stay up to date on the newest technology.


I love watching Los Angeles sports teams including the Lakers, Rams, Dodgers, and Kings. My favorite movie series is Star Wars, and my favorite TV show is How I Met Your Mother.

Volunteer/Service Experience

USC Mobile Clinic, Queenscare


As a third-generation dentist who was raised in Rossmoor, I am pleased to be able to give back to my community. When I am not in the office, you can find me surfing, on the beach, snowboarding, and golfing. I played water polo at Los Alamitos High School and Pepperdine University.
