Meet the Doctors

Seth A. Vaccaro, M.D.

Chosen by Los Angeles Magazine as one of Los Angeles’ “Super Doctors”, Dr. Vaccaro has maintained a practice in dermatology in Pasadena for over thirty years. He is also a Clinical Associate Professor of Dermatology at USC.

Dr. Vaccaro’s office was exactly what I hoped for – direct, efficient, human, reasonable. As a new patient, I was immediately and warmly greeted. My name was called exactly at the appointment time. One assistant accompanied me to the exam room and Dr. Vaccaro joined me within about one minute.  He did a thorough examination, rendered his diagnosis with an easily understood explanation, and a prescription which included generic alternatives. I absolutely recommend Dr. Vaccaro.

Meet the Doctors

Janice L. DaVolio, M.D.

Named as a “Top Doctor” in both San Gabriel Valley as well as Pasadena, Dr. Janice DaVolio is both a highly regarded Dermatologist as well as a Clinical Associate Professor of medicine at the University of Southern California. 

Dr. DaVolio has been my dermatologist of choice for years! She is always very professional while maintaining a personal relationship. She has children around my age so she has an inside to today’s world and what might be causing my skin issue. Dr DaVoilio always makes it feel like you are not just a patient but a friend by talking through any concerns or questions you have. Would highly recommend Dr. DaVolio to anyone searching for a dermatologist!!

Meet the Doctors

Joanna Chan, M.D.

Dr. Joanna Chan graduated from Harvard College, Stanford Medical School, and dermatology residency at UT Southwestern Medical Center in her hometown of Dallas, Texas.  Fellowship-trained and accredited by the elite Mohs College, Dr. Chan has presented at national conferences, published widely, and served as clinical faculty while training medical students and residents.  She has been repeatedly awarded Super Doctors®, Castle Connolly Top Doctors, Pasadena & LA Magazine Top Doctors, LA’s Top 10 Dermatologists by Motion Picture & Television Directories, American Cancer League Honoree, America’s Top Dermatologists, and more.

I went to Dr Chan for Mohs surgery for one squamous and one basel site both on my face. She is fabulous! I will use her for life! I drove 7 hrs from Northern CA to Southern CA to see her and plan to return in 6 weeks after fully healed. But after one week it looks super and I am pleased. She has the best disposition of any  doctor I have ever encountered and the SKILLS to match.  She called 4 hrs after surgery and a week later called and emailed me again. Wow! And I am a former RN so am tough on how I score a Doc. Dr Joanna Chan is TOP TIER.
