Get to Know Your Local Dentists

Dr. Kevin Badii

Managing Doctor and Orthodontist

Dear Patients and Friends of OC Smile,

Thank you for allowing me the opportunity to introduce myself to you! I am an Orange County native, and after graduating from El Dorado High School, I attended the University of Hawaii on a full football scholarship. Due to injury, I received my undergraduate degree, in Biology, from California State University at Stanislaus. While at CSUS, I served as the team captains for both the Men’s soccer and Men’s track teams. I received my Doctor of Dental Surgery (DDS) degree from USC School of Dentistry, where I graduated with honors and became a lifetime member of Omicron Kappa Upsilon, the esteemed National Dental Honor Society. I received my Specialty Orthodontic Certificate and Masters of Dental Science (MDS) Degrees from the University of Connecticut. I am a Diplomate of the American Board of Orthodontics, an extraordinary accomplishment achieved by a very small percentage of orthodontists.

My wife, Dr. Bonnie, and I have 3 beautiful children. We’re “OC Locals” and enjoy all the awesome amenities the area has to offer. In my free time, I enjoy spending time with my family, being active outdoors, and reading. I find importance in demonstrating solid values and morals, and I have always pursued excellence in my personal and professional life. I look forward to working with you to help create your beautiful, long-lasting, smile.

Yours in Health!
