About the Practice

In 2007, Dr. Stanley Poulos and Dr. Yngvar Hvistendahl founded Plastic Surgery Specialists, now known simply as PSS. Dr. Hvistendahl and Dr. Poulos share a unique passion for plastic and reconstructive surgery and believe that the individual surgical talent and years of experience they bring can be extended to the entire PSS staff to ensure excellence of service to all individuals.

PSS has grown over the years to a team of 20+ staff members. We are one of the most recognized and respected plastic surgery practices in Marin County and the greater San Francisco Bay Area. Dr Hvistendahl received the honor of being voted again “The Best Plastic Surgeon in Marin” by both Marin Magazine and The Pacific Sun.

The addition of our very active medical spa on-site in our 6,000-square-foot clinic allows us to provide nearly every surgical and non-surgical aesthetic option for our patients. Our team is dedicated to innovation and results and constantly adding new technologies in skin tightening, weight loss, women’s intimate health, hair restoration, injectables, and more.

We pride ourselves on providing safety and comfort without compromise and hold each practitioner to the highest standards for surgical and non-surgical procedures. If you are considering surgical or non-surgical cosmetic procedures, we invite you to request a consultation online or call (415) 925-2880 to make an appointment with one of our board-certified plastic surgeons. People in all parts of Marin County and the San Francisco Bay Area travel to our Greenbrae clinic for the superior care we provide our patients.

A Team Approach

Our experienced team of providers, who approach aesthetics from extensive personal experiences, combine a unique individual cosmetic perspective, and through attentive discussion and collaboration with each patient, each provider gives a unique approach and applies these skills to achieve each patient’s desires.

Our team of versatile and individual plastic surgeons are all board-certified with extensive training in both aesthetic and reconstructive plastic surgery. Selecting the right provider for each individual ensures a good match resulting in a transparent and serene relationship starting from the initial consultation, the procedure itself, and the post-op care.


Our on-site medical spa, SpaPSS, supports our surgical practice by providing aesthetic, non-surgical treatments in a discreet and tranquil atmosphere. We offer a wide variety of injectable dermal fillers and Botox to maintain a youthful and confident look. We offer a full range of non-invasive body treatments as well including body contouring, skin tightening, skin resurfacing, laser hair removal treatments, and hair restoration. We take great pride in using the most advanced technologies for our patients including CoolSculpting, Emsculpt, the radio frequency-based Venus Legacy and Accent-Prime, Skin Tyte infrared laser, the state-of-the-art Halo Hybrid Fractional laser system, Venus Viva, Microchanneling with PRP, Soprano Ice hair removal laser, Hydrafacial® treatments as well as treatments for women’s intimate health.

We’ve also added the NeoGraft hair restoration system – a wonderful option for both men and women. NeoGraft produces dramatic natural results and permanent hair restoration without the need for a linear scar across the back of the scalp. When combined with a series of PRP treatments and our Nutrafol Vitamins, our patients see incredible results.

We’re also excited to assist patients working to lose significant weight (30-70 lbs) with the PSS Health & Wellness Weight Loss Program. This program combines a well-designed health and wellness plan with the technology of the Orbera®  Gastric Balloon. This treatment consists of inserting a saline-filled balloon endoscopically to occupy space in the stomach, preventing overeating and allowing for sustained weight loss while being supported by nutrition and exercise specialists.

Lastly, we offer convenient payment options to make either a big surgical procedure or regular maintenance affordable.
