Kuchnir Dermatology & Dermatologic Surgery

Our dermatologists work closely with primary care physicians, other specialists, and subspecialized dermatologists to ensure teamwork and continuity of care. Each of our clinicians is an expert in diagnosis as well as medical and surgical treatment of all diseases of the skin, hair, and nails. We often perform diagnostic testing on skin in the office at the same visit. When necessary, we can conveniently arrange for prompt surgical treatment, including Mohs micrographic surgery. We can also provide extensive patch testing in our Contact Dermatitis Clinic.
The academic mission of the practice exposes our medical students and residents to scientific and practical approaches to dermatology. Our dermatologists also give several lectures each year to enhance the dermatology component of our training programs. Our dermatologists have contributed over fifty years as faculty of the UMass, Harvard, and Tufts Medical Schools.
Our dermatologists are available for inpatient and emergency consultation at Marlborough Hospital, Milford Regional Medical Center, MetroWest Medical Center, Emerson Hospital, and at each campus of UMassMemorial, Worcester.
