Our Location

We are located in the heart of the historic village of New Preston, CT, the quintessential New England town, easily accessible from all neighboring towns in Litchfield county and beyond and only 90 miles north of New York City.

Our Philosophy

As fellowship-trained dermatologic surgeons we understand the importance of practicing precise and evidence-based medicine, thoughtfully applying core concepts of science to each procedure and decision we make to treat our patients.

From an esthetic standpoint, it is our belief that beauty is unique and can be expressed in different ways. We are therefore passionate about achieving personalized standards of beauty for everyone, with results that are effective yet understated and age-appropriate. Our belief in an uncompromising natural sense of aesthetic allows our patients to reflect who they are through a new-found radiance and confidence of their skin without ever looking obvious or “overdone”.

About Dr. Andreas Boker

Dr. Boker is a Board-certified dermatologist with specialized fellowship training in surgical, procedural and cosmetic dermatology. He has been a practicing dermatologist in New York City for over 10 years and divides his time between an active private practice in Manhattan and teaching at the Ronald O. Perleman Department of Dermatology at NYU Langone Medical Center. In his role as attending physician at NYU, he oversees the teaching of procedural and cosmetic dermatology to senior dermatology residents.

He has been recognized as a “Top Doctor in the New York Metro Area” by Castle Connolly for the last 5 years in a row and was named as one of New York Magazine’s Top Doctors in 2021.

He completed his general surgery internship at Tufts New England Medical Center, followed by a fellowship at the Department of Dermatology at Harvard’s Brigham and Women’s Hospital. During his time at Harvard, he spearheaded research studies investigating groundbreaking dermatologic treatments and devices, including innovative biologic drugs for psoriasis.

He then completed his dermatology residency at the University of Texas Southwestern, one of the most rigorous and renowned dermatology residency programs in the country. There he was elected chief resident and was honored to receive the Phil Eichorn award in recognition of his outstanding academic performance and commitment to patient care.

Following his residency, Dr. Boker went on to complete his fellowship training in Procedural Dermatology and Mohs Surgery at the Department of Dermatology of the University of California San Francisco.

He has extensive experience in the treatment of skin cancers. Using Mohs micrographic surgery, a highly specialized, minimally invasive procedure, he is skilled in removing skin cancers from critical anatomical sites which he then reconstructs with advanced plastic surgery techniques.

He also has vast expertise in the field of cosmetic dermatology. He conducted many of the key clinical trials that led to FDA-approval of a variety of injectables including Botox, Restylane and Sculptra.

He has published widely in both the medical and cosmetic dermatology literature, authoring multiple peer-reviewed articles and textbook chapters on topics in both areas of dermatology.
