About Me

I grew up in Seattle, Washington, but became a Californian through my education at University of California, San Diego, and University of California, Davis School of Medicine. I chose to become a dermatologist from an early point in my career and have not regretted it in the least. Dermatology is an exciting specialty that challenges me every day with a diversity of interesting skin conditions and patients.

Having trained in dermatology at Henry Ford Hospital in Detroit, Michigan, I have extensive experience in phototherapy and interest in treating ethnic skin of many types, in addition to general dermatologic conditions and skin cancer. I have taught future dermatologists on staff at the University of Pittsburgh Medical Center, and take pride in keeping myself current with developments within my specialty.

In addition to my general dermatology clinic at Martinez, I also have a cosmetic clinic in San Ramon. My goal is to help people stay confident by maintaining a natural, healthy outward appearance. It’s not about turning back the clock, but presenting the best possible version of ourselves.

Choosing Kaiser Permanente as a physician was truly a family decision. There have been a total of four Dr. Mates at Kaiser Permanente, including my mother-in-law, father-in-law, and my husband. Outside of work, I enjoy running the area trails and spending time with my husband and three children.
