Branch Leadership Team

When people are in the position of having to teach others, they're going to take a closer look at how they're practicing. It just creates an environment for optimal, gold-standard health care. And this community deserves that.

Dr. Mary Ann De Groote was born on a U.S. Air Force Base in Germany but grew up in Iowa.  After Medical School at the University of Iowa, she moved to Colorado for Internship in 1988 and has been here ever since.  She completed not only her internship, but residency, Chief Residency, and ID Fellowship at the University of Colorado. She has always loved animals and has had a long-standing interest in Infectious Diseases.  One of her first jobs as a teenager was cleaning dog and cat kennels at a local veterinarian’s office, and when they offered her a chance to come out of the slop and help search for hookworm eggs in the fecal flotation test, she was “hooked” on ID. She initially thought that a career as a DVM was the right path, but ultimately veered toward human medicine.  She has had a rewarding career as a longtime practicing Infectious Disease physician in the local Denver/Boulder area. She loves microbiology and the challenging and interesting cases.  An ID doctor needs to know and understand all of medicine and keep up on the ever-changing medical knowledge base to be effective. Mary Ann has appointments at CU Anschutz and CSU and has really enjoyed being part of the new branch campus and helping it mature into a wonderful place to learn and grow the next generation of physicians.  Outside of work, she enjoys biking, hiking, and spending time with her husband and two crazed rescue Labrador retriever mixes (like many Coloradoans)!  It is a joy to be part of this amazing program.
