Katy Duffy, PA-C

Katy Duffy is a native of Mason City, IA. She graduated cum laude with her bachelor’s degree from the University of St. Thomas in St. Paul, MN. She then earned her Master of Science in Physician Assistant Studies at Des Moines University in 2014 and has specialized in dermatology ever since. She completed the Society of Dermatology Physician Assistants’ Diplomate Fellowship program in 2020.

Katy enjoys seeing patients of all ages and is passionate about helping them achieve confidence in their skin. Her practice mainly consists of medical dermatology including full body skin exams and mole checks for skin cancer detection, as well as treatment and management of various dermatologic conditions including acne, psoriasis, eczema, rosacea, warts, hair loss, vitiligo and more. She is also trained and administers Botox. Katy believes the most important part of patient care is making her patients feel comfortable while building a relationship based on trust and mutual respect.

Outside of work, Katy enjoys spending time with her husband and three young kids. When she’s not busy chasing her kids around, she likes to read, do yoga and go for walks with her labradoodle, Lucy.
