HMKillMolly Kozlowski, PA-C, although new to Advanced Dermatology Care, is not new to the field. Molly comes to us with over 10 years of experience as a board-certified Physician Associate in Dermatology. Molly, a native of northeastern Indiana, graduated from DePauw University in 2005 with a Bachelor’s degree in Psychology and concentration of studies in Chemistry. She later matriculated from the University of Saint Francis in Fort Wayne, Indiana with a Master’s in Physician Associate Studies in 2009.

Molly prides herself on building long-lasting relationships with her patients, founded on trust and communication. She emphasizes the importance of educating patients on disease states and exploring treatment options with each patient to fit their lifestyle. “An understanding of disease leads to an understanding of it’s treatment, and an increase in successful treatment.” Treating both children and adults, Molly provides medical, surgical, and cosmetic dermatological care. Molly also enjoys non-surgical facial rejuvenation – she believes that the most ideal outcome in any cosmetic procedure is a ‘natural’ and ‘refreshed’ appearance. “The best compliment someone can give to my work is that no one noticed drastic changes; they just noticed I looked better, and couldn’t put their finger on it.”

Outside of work, Molly enjoys spending time outdoors, and taking advantage of the diverse activities Minnesota has to offer. She’s fond of hiking with her family, and frequents many of the local dog parks with her two dogs (Ajax and Freya). She has a growing family with one young daughter and one on the way.
