Message

Dear Friends,

I would like to take this opportunity to introduce myself and express my warmest regards to the community here in beautiful Orange County, California.
After growing up in Newport Beach, California, I attended the University of California at Irvine for my undergraduate studies in Physical Chemistry. I then decided to follow in my father and elder brother's footsteps and set off to pursue graduate studies at Columbia University where I earned my Doctorate in Dental Surgery and eventually served as a clinical instructor. Although I embraced the opportunity to study and work amongst many of the world's most esteemed and renowned dentists, I always knew that I would someday return to Orange County, California, and serve the community in which I was raised.
With the cooperation of my staff of medical professionals, we seek to provide the community with the finest dental care available in our region. We are fortunate to have state of the art facilities that allow us to provide the most advanced dental care in the safest and most comfortable environment possible.
Contrary to popular belief, the great majority of dental procedures today are virtually painless, if carried out correctly. We believe that visiting the dentist does not have to be an unpleasant experience, and we will do everything within our power to provide you with the finest dental care in the most comfortable manner possible.
We look forward to helping you care for your dental health and hygiene, as well as resolving any dental issues that you may have so that we can get you started on a preventive care program that will keep you happy and healthy.

Sincerely,
David S. Hahn, DDS
