    College: Boston College

    Hometown: Mansfield, MA

    Nick grew up in Mansfield, MA, and attended Boston College where he studied biology. His interest in dermatology began during a gap year position before medical school, where he worked in a local dermatology office and began to understand the wide range of dermatologic conditions and the multitude of treatment modalities that can be offered. He later attended UMass Chan where he expanded his exposure to the field through projects specifically focusing on rheumatology-dermatology, pediatric-dermatology, and dermatologic surgery. He currently completed his intern year at Cambridge Health Alliance and is very much looking forward to rejoining the UMass Derm family. Nick is passionate about mentorship and patient care, and is eager to continue building on both early in dermatology residency. In his free time, Nick enjoys being a foodie with his wife Steph, traveling to new areas, and pretty much any outdoor activity.
