Becca McCaskell, CNP, FNP-C
Nurse Practitioner in Aberdeen, SD
Aberdeen Dermatology Associates
Becca earned her Bachelor of Science in Nursing from the University of South Dakota and became a board-certified Registered Nurse in 2016. She later completed her Master of Science in Nursing at South Dakota State University, becoming a board-certified Nurse Practitioner in 2019.
After graduation, Becca began her nurse practitioner career in hospital medicine before transitioning into wound care. While she loved serving patients in both roles, she felt called to build something more personal. She watched women in Huron drive more than 75 miles for advanced aesthetic care and realized her community deserved that level of expertise close to home. She did not need to leave to build something meaningful. She just needed to believe it could be built here.
That belief led to the founding of Luxe Med Spa, where Becca provides elevated, natural first aesthetic care to Huron and the surrounding communities. Her philosophy is simple. You should walk in feeling nervous and walk out feeling like yourself, just more rested and refreshed. No overdone results. No pressure. Just thoughtful care, education, and expertise you can trust.
Becca has pursued extensive advanced training in aesthetic medicine. Her education includes neurotoxin and dermal filler training through the American Academy of Facial Esthetics, advanced filler coursework with Revive Academy, and mentorship in full facial balancing with Amie Martin. She has completed advanced neurotoxin and filler training through GAIN Training with Shelby Sanders and is certified in Radiesse biostimulator treatments through Ellen’s Aesthetics PACE program. She is an active member of the American Association of Nurse Practitioners and supports local initiatives, especially those that empower women owned businesses.
Originally from Huron, Becca is proud to serve the community she still calls home. Outside the clinic, she spends time with her daughter Haelyn, stays active with workout classes, and is always planning her next trip somewhere warm. She is passionate about helping women feel confident in their skin and values the long-term relationships she builds with each patient.
