“Our goal is to find the simplest, most straightforward solution to your skin’s needs.”
– Dr. Ellen Marmur


We believe that health and beauty are intimately connected. Your skin’s appearance reveals a great deal about your overall well-being, and taking care of your skin involves a holistic approach to your lifestyle, including exercise, diet, sleep, and even happiness.

Your body is already equipped with the most amazing, sophisticated mechanisms of rejuvenation and repair. Our goal is to support those wonderful systems to optimize your body’s own natural anti-aging efforts, and to step in where needed to treat skin cancer or other areas of concern.

Our approach to both sides of our practice — skin cancer diagnosis and treatment, and cosmetic dermatology — is the same: we work closely with our patients to collect as much information as possible, we discuss and assess possible procedures (including innovative, leading-edge processes), and we proceed with the simplest, most straightforward solution, tailored to the patient’s particular needs and concerns. And in all aspects of treatment, we maintain the respect, compassion, and utmost focus on safety that each of our patients deserves.

Dr. Marmur believes in Preservation Aging®. We want to preserve our healthy skin and prevent the signs of aging and look like our healthiest, best selves–not like anyone else. Cosmetic surgery can be natural and unnoticeable! You might hesitate and say–why wouldn’t I want it to be noticed? Preservation Aging® means you just look great! Somehow, mysteriously, you have a magic trick that makes you not age as fast as you might have otherwise! Utilizing the power of fillers, Thermage, and other laser treatments in your personalized Master Plan in consultation with our team, you will benefit from stealth cosmetic surgery and Preservation Aging®Ultimately, we want to enter into a partnership with each of our patients, with the goal of helping you develop and commit to a lifestyle that makes you healthier, stronger, and more radiant.
