Adrienne Ide, DO

Since moving to Colorado, I have loved the wonderful outdoor activities the Rocky Mountains provide. Whether it’s hiking in the summer or skiing in the winter, I’m happiest outdoors. I’m a lover of travel, a binge watcher of Friends, and am always up to try the newest brunch place! This program helped make me into the doctor I am today. The residents and staff truly enjoy working with one another and it creates a wonderful learning environment. I am excited, as a former resident of this program and now faculty, to see this program continue to grow and evolve as it shapes future family physicians.
