The Mission of the Diabetes Society is to improve the lives of people affected by diabetes through education, advocacy, support services, and partnerships.

For over 40 years, the Diabetes Society has been providing education and one-on-one consultation to individuals with diabetes, and educating the general public about the seriousness of the disease. The Diabetes Society was organized in 1963 as the result of efforts by a group of mothers of children with diabetes. Today, the Diabetes Society is the only organization in California that provides as extensive a range of services and programs for people of all ages who live with diabetes.

The Diabetes Society is an independent organization with no regional, state, or national affiliations. The Diabetes Society's operations are funded through donations from individuals, foundations, corporations, service clubs, special events, fees for service, and membership dues.

The Diabetes Society's health education programs provide for proper medical management of diabetes through education, one-on-one counseling with a registered nurse and/or dietitian, individualized diet and exercise plans, support groups, and educational camps for insulin dependent youth. The American Diabetes Association (ADA) recognized the Diabetes Society for meeting its national standards for diabetes self-management education. In addition to educational programs for the community, the Diabetes Society provides education for health care professionals, blood-glucose screenings, and participation in numerous workplace and community health fairs. The Society partners with numerous device and pharmaceutical companies in providing clinical trial opportunities.
