Kelsey Mason, FNP-BCKelsey Mason, FNP-BC

Kelsey Mason earned her Master of Science in Nursing – Family Nurse Practitioner Degree in 2013 from Cox College in Springfield, Missouri where she graduated at the top of her class. Prior to that, she received her Bachelor of Science in Nursing Degree from Truman State University in Kirksville, Missouri in 2010 where she graduated magna cum laude.

After graduating, she practiced internal medicine/pediatrics as a foundation to her eventual goal of exclusively practicing dermatology. She has always had an interest in dermatology and treated a wide variety of skin conditions within the scope of her internal medicine/pediatrics practice. She was initially drawn to dermatology because of her personal experience as a former acne patient, and the way in which its treatment helped to optimize her overall self-confidence as a teenager.

She later became Southern Illinois University Division of Dermatology’s first mid-level provider and also served as an adjunct faculty member. Kelsey’s clinical interests include skin cancer detection and management, acne, rosacea, eczema, and psoriasis.

The most rewarding part of her job is providing patient education on best skin care practices and developing relationships with her patients in order to customize treatment plans to their specific dermatologic needs. Recognizing the psychosocial impact that dermatological conditions can have on a patient, she seeks every opportunity to improve skin conditions and thereby improve quality of life.

Kelsey is a member of the Sigma Theta Tau International Nursing Honor Society, the Dermatology Nurse Practitioner Society, and the Dermatology Nurses Association.

When not treating patients, Kelsey enjoys lap swimming, traveling, scuba diving, hiking, writing, playing the piano, St. Louis Cardinals baseball, and spending time with friends and family.

Kelsey Mason is accepting new adult and pediatric patients for medical, general, and cosmetic dermatology.
