Our mission is to be the recognized source of information on dental issues, to serve members' professional needs and issues, thereby enhancing their ability to serve the community. The San Diego County Dental Society (founded in 1887) is the largest professional organization representing dentists in San Diego and Imperial Counties, as well as being the local arm of the California and American Dental Associations. Membership is voluntary. More than 70 percent of dentists in the San Diego area (approaching 2,000) are currently members.
