I have been working in the dental field since 1992, where I worked as an assistant in every branch of dentistry including orthodontics and oral surgery. I graduated from the Diablo Valley Dental Hygiene program in 2003, where I received the Distinguished Graduate Award.

Spending this quality time with my patients has enriched my life. I enjoy following my patients’ lives, just as I enjoy sharing my own personal life with them. In my personal life I enjoy spending time with my 4 children. Fun fact – I was born in England and immigrated to the U.S. when I was 5!
