Welcome to San Luis Dermatology & Laser Clinic

The San Luis Dermatology and Laser Clinic has been serving the San Luis Obispo area in the person of Dr. Jeffrey Herten since October, 1977. From a one doctor, one nurse, one front office person practice in an 800 square foot office, the clinic has grown into a four physician, and twenty support staff practice in a state-of-the-art 3900 square foot facility, and newly added second location.
