Tess is a board-certified nurse practitioner bringing over a decade of training and professional experience in the areas of internal medicine, clinical research, plastic surgery, dermatology, and her true passion, aesthetic medicine.

She received her BA in French from Wellesley College, and a combined BSN/MSN with academic honors in advanced nursing from Harvard's teaching hospital, Massachusetts General.

Tess is a proud San Francisco native. As the daughter of a UCSF physician-scientist and a Stanford documentary filmmaker, she inherited not only a passion for healthcare and the arts, but also an exceptional personal standard of excellence. 

Tess lives with her husband, young son, and rescue chihuahua, Leeloo. She enjoys all things French, gluten-free baking, family time, international travel, and ballroom dancing.

my philosophy

My practice is centered around the individual, emphasizing each client’s natural beauty, treatment goals, and lifestyle.

I view each consultation as a partnership. You bring the intimate knowledge of yourself - your concerns, your goals, your values. I bring medical expertise, aesthetic training, and honest feedback. Together, we create a treatment plan that achieves results that feel authentically you.

I  use a multimodal, yet practical approach to my care combining skin-priming and preventive topicals with evidence-based, customized injectable and biostimulating treatments.

My ultimate goal is for every patient to be inspired, confident, and feel genuinely cared for.
