Our Team

Welcome Message from Program Director Sarah Mayson, MD

Mayson-250Thank you for your interest in the Endocrinology Fellowship training program at the University of Colorado! We offer a rich training experience that encompasses the entire spectrum of clinical endocrinology, as well as diverse opportunities for research, all in a beautiful and exciting location that is renowned for fantastic hiking, skiing and snowboarding, and lots of sunshine year-round! 

Our core training facilities include 3 teaching hospitals:  the University of Colorado Hospital (UCH), the Rocky Mountain Regional VA Medical Center (RMR VAMC), and Denver Health Medical Center (DHMC). UCH was once again ranked #6 in the nation for Diabetes and Endocrinology by U.S. News & World Report in 2018! The Endocrinology division at the University of Colorado is one of the largest in the country with over 40 faculty and many more in associated divisions and departments who are committed to teaching and mentoring fellows.

Although all of our fellows receive broad, in-depth clinical training in endocrinology and diabetes, we are also able to tailor the fellowship experience according to the clinical and/or research interests and anticipated career path of each individual. We offer a 2-year clinician-educator pathway and a 3-year research track (with research focused 2nd and 3rd years), which share an identical first year. We do not require that our fellows determine their chosen pathway until mid-way through the first year of fellowship. This provides some flexibility for our trainees, as we realize that their goals may evolve after starting fellowship training.

Please feel free to reach out to me via email at Sarah.Mayson@cuanschutz.edu, or our Fellowship Program Coordinator, Caroline Whitaker, at (303) 724-8098, or Caroline.Whitaker@cuanschutz.edu​ if you have any questions.

Thank you for considering our program!
