Denise Michelle Neff

MSNEd, APRN, FNP-C

Nurse Practitioner

Denise Michelle Neff, MSNEd, APRN, FNP-C is a board-certified Family Nurse Practitioner, the founder of The Refinery Medical Spa & Wellness Clinic, and — above all — someone who genuinely loves helping people feel like themselves again. After more than two decades in clinical medicine, including years as a nurse practitioner in gastroenterology and pain management, Denise had a vision: a place where medical-grade care and heartfelt hospitality come together under one roof. Five years ago, she made that vision a reality alongside her daughter, Whitney Sampsell, a talented Certified Aesthetician and the clinic's Practice Manager, whose eye for beauty and passion for skincare make her an irreplaceable part of everything The Refinery is. Behind the scenes and always in her corner is her husband, Dr. Ward Neff, M.D. — a board-certified Internal Medicine physician whose expertise and steadfast support give the practice an added layer of medical depth and collaboration. Together, this family team has built The Refinery into a trusted destination in Newburgh where patients come for GLP-1 weight management, peptide therapy, aesthetic skincare, aesthetic injectables, non invasive body contouring, laser services, and so much more — and our clients keep coming back because they feel truly cared for. At The Refinery, you're not just another person walking through our doors. You're family.
