Tess Aberg, FNP-BC is a San Diego native and nurse practitioner with over 15 years of nursing experience. She currently serves as both a certified wound care nurse and family nurse practitioner in the Rehabilitation and Physiatry Department at Rady Children’s Hospital. Her passion for skin health is deeply personal—shaped by her own experiences with acne, skin cancer, and years of clinical practice in wound care—which ultimately inspired her dedication to aesthetic medicine and skincare.

Tess has continued to expand her expertise in aesthetics over the last several years, offering evidence-based treatments that emphasize natural, long-lasting results. She has a particular love for microneedling, a treatment she often highlights for its ability to deliver impressive results across a variety of skin concerns, especially when combined with regenerative options. She also specializes in biostimulators such as Sculptra, HD Radiesse, and PRF/EZ Gel—treatments that go beyond volume to restore structure, improve skin texture, and enhance elasticity for subtle yet transformative rejuvenation.

Her philosophy is simple yet powerful: to help her clients look like themselves—refreshed, confident, and naturally radiant.

Outside of her clinical practice, Tess enjoys exploring San Diego with her husband and their three dogs. She finds joy in hiking, reading, discovering new restaurants, and attending live music events that keep her connected to the vibrant energy of her hometown.
