About Us

Dermatology Associates signDermatology Associates was founded by Marcos Sastre, M.D. In 1981. At that time Dr. Sastre took over a large practice in Quincy, MA from a dermatologist who decided to move to Florida.

Over the years new offices were opened in the towns of Marshfield and Sandwich thus covering
the South Shore and expanding into Cape Cod.

In 2006, a new building with 3,600 square feet of office space was built from the ground up to accommodate the rapidly expanding patient population.

Our staff of thirteen health care professionals includes a registered nurse, 3 medical assistants, medical secretaries, record keepers and a health care coding specialist.

We are, in sum, like a family dedicated to the service of our patients for almost 30 years. When you visit our office, you will see that our practice is very different from that of any
dermatologists that you might have had experience with in the past.

Our European ambience with a central fountain, Greek statues, interior gardens and friendly
staff is intended to define a new way of service to our patient community. With thirty years of
experience in dermatology we are in an unique position to understand your needs and solve
your very personal skin problems.

Chances are that some of your friends or family members already come to us, for state of the
art dermatology service.
