In 2002, Dr. Jeffrey Sugarman started this practice as a solo physician practicing predominately pediatric dermatology. The practice grew organically and in the ensuing years added adult medical dermatology, Mohs surgery, phototherapy, histopathology services, and cosmetics including the latest injectables, lasers and rejuvenation. In 2006, we opened a satellite office in Ukiah which allows us to help the patients from northern and coastal areas of California.

Together we strive to be leaders in management of skin health and skin disease by providing the highest level of care, and offering outstanding service. Our providers are committed to clinical, professional, ethical, and academic excellence through active engagement in ongoing medical education, sensitivity to our patients’ needs, and community service.
