  • I am board-certified in both Endocrinology & Metabolism and Internal Medicine. From 2014-2021, I practiced at Ann Arbor Endocrinology & Diabetes Associates (, affiliated with St. Joseph Mercy Hospital in Ypsilanti, MI. While at "St. Joe's" I was also a Key Clinical Faculty Member in the St. Joseph Mercy Internal Medicine Residency Program, and worked as a supervising attending physician at the Academic Internal Medicine Clinic. In January 2022 I returned to the University of Michigan as full-time faculty in Endocrinology & Metabolism at VA Ann Arbor Health System, serving as Assistant Chief of Endocrinology & Metabolism. My interests include general endocrinology, type 2 diabetes, medical education, quality improvement, and teaching other physicians and providers how to better care for patients with diabetes.
