Anna Buck, DO

Hello there! My name is Anna Buck. I was born and raised in Minnesota and attended the University of Minnesota for my undergraduate education. I moved to Colorado in 2019 to attend medical school at Rocky Vista University and loved it so much, I stayed for residency! I love working with a diverse
population of patients and have special interests in global health, reproductive care, and lifestyle medicine. In my free time, you can find me on the running trails, attending yoga classes, snuggled up
with a good book and my rescue puppy, or baking one of my favorite recipes. I can’t wait to continue my learning as a part of the HealthOne Family Medicine Residency Program!
