I grew up in Martinez, California and have lived in Napa, California for the last 25 years.  I became interested in aesthetics in 1995 while attending Los Medanos college, and wanted to open my own skincare clinic. In 1996, I opened the Renew clinical skincare in Concord, California and operated it until I joined Kaiser Permanente San Francisco Dermatology in 2001.  After having my son, I had the opportunity to transfer to Kaiser Permanente Vacaville in 2008 to be closer to home.  I started the Cosmetic Dermatology program in Vacaville that offers medical grade products and procedures, including chemical peels, microdermabrasion and acne treatments.  Working hand-and-hand with our dermatology team we provide the best possible care.


UCSF – Minimally invasive surgery

UCLA – Cosmetic Chemistry


When I am not at work, I enjoy spending time in my olive orchards or riding my horses.
