Dr. Kallgren has been our dermatologist for 15 years. She is an exceptional doctor who treats patients with respect, somehow managing to be attentive and thorough but also always punctual.

This clinic is compassionate and friendly! Nice assistant, nice doctor and a great outcome with a problem that is painful and embarrassing. Another doctor didn’t even try. Many thanks to Kallgren in Boulder.

After going to several other dermatologists for a seemingly unsolvable problem, this place was recommended to me by one of my physicians. They did a painless and quick biopsy, prescribed me a steroid cream without hydrocortisone in it (finally), and the problem went away in 2 weeks, after two years of struggling. All the while, they were very easy to work with, professional, and kind.
