The mission of Greenbrae Dermatology is to provide excellent dermatologic care along with ethical, skilled, personalized service. Our team offers a wide array of medical, cosmetic, and surgical dermatology services, including the diagnosis and treatment of skin cancers. We are committed to treating every patient with compassion and individualized service in a warm and friendly environment. We look forward to meeting with you and helping you take the best possible care of your skin. 

Please use this website to learn more about us and our services as well as access to wound care instructions, medication instructions and skin care routines that you may find helpful.  

We offer links to websites that offer dependable medical information.  

Please let us know if there is anything you would like us to add to the site to make it more useful for you. Unfortunately, because of stringent medical privacy laws, we are unable to offer email connections.

We are temporarily experiencing a rather long wait time for new patients. We are presently having a severe backlog and we wish to maintain adequate access for our existing patients. We will try to accommodate new patients to the best of our ability. Please call for an appointment in any case as we try to keep our cancellation lists up to the minute.  We apologize for any inconvenience.
