Dr. William D. Sansum, who brought renown to Santa Barbara in 1922 as the first physician in the U.S. to produce and administer life-saving insulin to patients with diabetes, founded the nonprofit organization in 1944.

Today, under the leadership of Ellen Goodstein, the William Sansum Diabetes Center remains an extraordinary place, where research, education and care have improved the lives of people worldwide who are impacted by this serious disease.

The Center has gained international recognition for its work to develop an artificial pancreas, its success in developing protocols to increase the incidence of healthy babies born to women with diabetes and its work with people with and at risk for type 2 diabetes. Physicians and researchers continue to develop new treatment protocols for people with diabetes. New drugs and medical devices are clinically tested to ensure their efficacy and safety.

It is our intention to use our past and present accomplishments to guide us into the future – to tap into the energy and commitment that made the William Sansum Diabetes Center what it is today – a worldwide leader in diabetes research, education and care.


About Us-2-HistoryDr. William D. Sansum at the time he established the Sansum Clinic at Cottage Hospital in 1928.


Dr. William David Sansum, founder of the William Sansum Diabetes Center, was born in 1880. He started pursuing his goal of being a doctor at Rush Medical College at the University of Chicago. Cottage Hospital’s board of trustees invited him to Santa Barbara to become the new Director of the Potter Metabolic Clinic.

While Dr. Sansum was pursuing diabetes research in the early 1920’s, other researches were doing the same and successfully treated animals and ultimately humans with an extract they developed. They named their extract “insulin”, from the Latin for “island”, referring to the Islets of Langerhans found in the pancreas. In Santa Barbara, Dr. Sansum decided to pursue the same direction— the production of insulin from animal pancreases. Researchers everywhere were trying to develop better methods and to increase purity and strength for use in humans with limited amounts of insulin available. On May 31, 1922; after two years of research the first American patient was injected with U.S.-made insulin at the Potter Clinic.

In 1928, Dr. Sansum decided to form his own clinic group with a staff of five. Later, Dr. Sansum was encouraged to build a clinic on Pueblo Street. Dr. Sansum retired from active practice in 1942, but continued his research efforts. In 1944 he founded the Sansum Clinic Foundation. Later the Foundation’s name was changed to Sansum Medical Research Foundation and to Sansum Diabetes Research Institute, and is currently the William Sansum Diabetes Center.

In 1947 Dr. Sansum began work on a new vision that was thirty years ahead of his time– pancreatic cell transplantation. A year later he suffered a stroke and died. After Dr. Sansum’s death, the clinic was reorganized and purchased by six of the doctors on the staff. The research foundation, headed by Dr. Alfred Koehler, continued to work on the projects that Dr. Sansum had been involved in.

In 1966 a two-story building that still houses the William Sansum Diabetes Center today was built with a gift from Mr. and Mrs. Harry Morrison and others. Full-scale diabetes research began soon thereafter in the Morrison Laboratories under Dr. Donald McMillan.

Although much has happened since 1920, one thing has not changed– the goal to cure diabetes, or at least to alleviate the problems caused by this devastating disease. The legacy continues today under the leadership of Ellen Goodstein, who was appointed Interim Executive Director in 2015.

Summer Internship Program in the Biologic/Medical Sciences

The William Sansum Diabetes Center’s Summer Internship Program, funded by the Coeta and Donald Barker Foundation, has a primary focus on diabetes mellitus, but interns learn about and are involved in a wide variety of clinical research and medically oriented activities. Providing insight into both clinical and academic medicine as well as medical research, this internship program offers a comprehensive learning experience for upper-class undergraduate students or recent college graduates interested in a biomedical or medical career.

Interns spend six to eight weeks (the dates of the program vary from year to year) at The Center. Interns (1) shadow The Center and community physicians practicing in various fields of medicine, (2) work on an assigned project contributing to the research or community outreach goals of The Center, (3) attend research program presentations by staff and visiting scientists, and (4) learn to critically review pertinent literature. There are weekly education sessions on diabetes mellitus and its treatment and complications. Interns receive instruction in many aspects of clinical research including writing, analyzing and presenting research results. Students with an interest or goal of a medical research or clinical career are encouraged to apply.

The successful applicant will have completed at least two years of college, preferably in a biomedical or pre-medical major. The ability to speak Spanish is helpful, but not required. Interns are responsible for housing and travel expenses. The post-mark or electronic-receipt deadline for submission of an application, including letters of recommendation, is April 1st, 2017.

The 2016 internship application is now closed. Please return in December 2016 to apply to the 2017 summer internship.

UC Davis graduate – “My experience as a summer intern was invaluable. My knowledge in diabetes research, care and treatment expanded in leaps and bounds.”

Stanford sophomore – “My internship allowed me to learn from some of the top scientists in the field of diabetes research.”
