She started her medical aesthetics journey in 2001 as co-owner and Medical Esthetician of a day spa. In 2008, she began an extensive career in aesthetic injectables using Botox and dermal fillers, which combined her love of clinical nursing and her artistic eye for facial balance, harmony and proportion.

She was recognized as one of the Top 15 Injectors by the Medical Aesthetic Associates (MAA) network, a group of over 100+ nurses who work under a core Plastic Surgeon as the Medical Director.

Kristen specializes in all injectable treatments including neorotoxins (Botox and Dysport), dermal fillers (Juvederm and Restylane products), Kybella, Sculptra, Radiesse (for neck lines and crepiness), PRP/PRF, Botox for axillary hyperhidrosis (sweating) and Botox for TMJ symptoms (jaw clenching).

Kristen is a member of the International Society of Plastic and Aesthetic Nurses (ISPAN), the Massachusetts Nursing Association (MNA) and the American Med Spa Association (AMSPA).
