Dermatology is a fantastic specialty for so many different reasons! My favorite part however, is getting to meet the diverse and wonderful group of people who live here in Bozeman, MT. Getting to know my patients over the years since opening my first office in May of 2009 has been my joy and privilege. The people in our community are truly unique, and I am proud to serve you. We have a wonderful team of people at Big Sky Dermatology designed to meet any dermatologic needs, including general dermatology issues like rashes or routine skin exams where our focus is on the earliest detection of skin cancers; skilled surgical management including Mohs surgery and excisions, and many Cosmetic options. I enjoy being involved in the creativity of selecting an approach to someone’s care that embodies the medical diagnosis, treatments available and every person’s unique needs and desires. For example, a skin cancer can involve Mohs surgery for complete margin control of a tumor and then the planning of a closure that will allow for the best surgical outcome for that person’s unique anatomy. Additionally, a person may need a more thorough workup or complete explanation of their diagnosis and treatment options in order to create a plan that will work for them. Aesthetics are very important, and we work hard to tailor our treatment plans taking into account any medical dermatologic needs while creating a personalized plan for whatever a person’s aesthetic goals might be. We all endeavor to give our patients an experience where they feel cared for, listened to and treated with respect. As a Montana native, I am so thrilled to be part of the Bozeman community. I couldn’t ask for a better location to raise my two daughters. When I’m not at the office, you might see us out and about in town, or on a bike ride, hiking, goofing off with the dog or just hanging out at home.

"This appointment was my first ever visit with a dermatologist. I wanted to get a couple of spots looked at and get a baseline on my overall skin health. Dr. Shannon was very gentle and explained everything she was doing. She answered my questions to my satisfaction."
