I attended Cal Poly SLO and studied Biological Sciences. I graduated from The Art Dugoni School of Dentistry in 1986 with my Doctor of Dental Surgery (D.D.S.) and in 1989 I received my Master of Science in Dentistry (M.S.D.) as well as my certificate in Orthodontics, also from The Art Dugoni School of Dentistry. I joined myfather in practice in 1989, the year I graduated. My dad and I practiced together for 15 years, until he retired. I feel very fortunate to be continuing in hisfootsteps.

I became a Board Certified Orthodontist in 1999. Certification by the American Board of Orthodontics is a distinction which confers the highest level of professional achievement in orthodontics. It requires examinations both written and oral, as well as case presentations. A Board Certified Orthodontist is also called a Diplomat of the American Board of Orthodontics.

I completed the Invisalign Teen Edge Program, a 12 month collaborative program in September 2017. This program is focused exclusively on treating teenagers with the Invisalign appliance. I have been the lead investigator in two completed clinical studies with Align Technology (Invisalign) and am currently the lead investigator in a third clinical study.

I belong to many organizations and am an active participant in organized dentistry.
