Katharine Vincent

Aesthetic Nurse Practitioner

Katharine, a Bethesda native, became an aesthetic Nurse Practitioner because this career combined two of her favorite passions: art and medicine. After attending Villanova University where she received her undergraduate degree in nursing, Katharine started working as a Registered Nurse in the Neonatal ICU at Georgetown University Hospital. After 3 years in the NICU, she left that position to pursue her dream of becoming a Nurse Practitioner. Enrolling in Columbia University’s Family Nurse Practitioner program, she also obtained a subspecialty in Women’s Health. While living in New York City, Katharine was able to work along side a very reputable Plastic Surgeon off of 5th Avenue. This experience helped to spark her love for aesthetic medicine.

Katharine is certified through Sciton to perform BBL/Halo laser treatments, acne treatments, and laser hair removal. She also provides micro-needling with platelet rich plasma (PRP) and chemical peels, which are both great ways to help improve skin tone and texture. She has experience with injectables such as Botox, Juvederm, Voluma, Kybella, Restylane and Dysport. Her aesthetic eye in combination with her belief that injectables should always look natural, leaves clients very satisfied with their results.

With her knowledge of medicine and intensive care background, Katharine strives to provide the best experience possible for her client. Her goal is to help people to exude the best possible version of themselves because she believes that “if you look your best, you feel your best”.

Outside of the office, Katharine enjoys staying as active as possible. She loves to go for long hikes, lift weights, and participate in various exercise classes. Katharine was a previous Pilates instructor and now coaches classes at F45 Training in her spare time. She also enjoys cooking, traveling and spending time with her friends and family.
