From the ICU to aesthetic medicine
Lia Yoon began her career as an Intensive Care Unit Registered Nurse, where precision, calm decision-making and patient trust were essential every day. She went on to earn her Doctor of Nursing Practice degree and has over 11 years of experience as a Nurse Practitioner in settings including dermatology, family medicine, pediatrics and orthopedics.
Her approach to aesthetic care is grounded in that clinical experience and guided by a deep respect for skin health and overall well-being. She explains every option clearly, recommends only what fits, and favors gradual, natural results over dramatic change.
Lia also holds certifications in homeopathy and as a lactation educator, nutrition coach, personal trainer and women's fitness specialist — a background that shapes how she thinks about the whole body, not just the concern in front of her. With roots in both ballet and martial arts, she understands firsthand how fitness and nutrition support how you look and feel.
Outside the treatment room, you'll find Lia with her family, trying a new recipe, or at a local barre class.
