About

Course Instructors

We are a team of physicians and researchers at the Barbara Davis Center for Diabetes at the University of Colorado School of Medicine. Our team has over 25 years’ experience working to understand childhood autoimmune disease. During that time, we have screened thousands of children and adults for early stage (presymptomatic) type 1 diabetes and helped hundreds of patients and their families understand the disease process and monitor for progression to symptomatic type 1 diabetes.

The Barbara Davis Center for Diabetes (BDC) specializes in Type 1 Diabetes (T1D) research and care for children and adults. It is one of the largest diabetes institutes in the world. The Center is part of the University of Colorado School of Medicine and has its dedicated building on the Anschutz Medical Campus in Aurora, Colorado.

 

The Center was funded by Marvin and Barbara Davis, in 1978, and is generously supported by the Children’s Diabetes Foundation (CDF)​.


Clinicians, clinical researchers, and basic biomedical scientists work at the BDC to find the most effective treatment, prevention, and cure for T1D. The Center provides state-of-the-art diabetes care to 4,600 children and 2,900 adults with diabetes from the Rocky Mountain Region as well as receiving national and international referrals. We also provide inpatient care to patients who are seen at the Children’s Hospital Colorado with any type of diabetes.


The Center’s faculty teach the medical, physician assistant, nursing, and dental students on campus. Residents and endocrinology fellows train at the Center on elective rotations. Basic science faculty members provide mentorship to pre-doctoral students and post-doctoral fellows from around the world.
