Nancy Serafini

Nancy Serafini has spent the past 35 summers on Nantucket with her husband Joe, while raising two children. Their family of four has expanded to 12 with two weddings and six healthy grandchildren.
Nancy graduated from Cedar Crest College and received a masters in urban affairs from Boston University. Having been derailed by poor advice from her middle school guidance counselor to pursue interior design, her father’s sudden death when she was 24 brought her back to Chamberlayne Junior College where she started to study design. In 1976, she started her own business HOMEWORKS with a $500 capitalization from her husband and with every intention of running a very small business from their Brookline townhouse.

Fast forward and HOMEWORKS grew to a staff of 1O, an allied membership in ASID, induction into the New England Design Hall of Fame and inclusion in over 30 magazines and newspapers. Nancy’s work was featured on 5 magazine covers and she received two awards from ASID - one for her work and the other for her volunteer efforts at Children’s Hospital Boston. Most recently she was honored to be the recipient of the Alumnae of the Year award from her alma mater Cedar Crest College. Her business has been rebranded to Nancy Serafini Interior Design, and Nancy continues to practice on Nantucket, Boston and Spring Island, South Carolina.

In 1998, her volunteer work with the Children’s Hospital League in Boston serendipitously lead her to start the Art for Kool Kidz program, along with two nurses, one of whom Kathy Malloy lived on Nantucket for a period and is a friend forever. They never conceived that their tiny project with a budget of $35,000 would be the kernel that ignited the hospital to recognize that the arts are an integral part of the healing process. The program is now valued at over $10 million and has artists in residence in music, poetry, dance and the visual arts. 

Most recently, Nancy has replaced her volunteer work at Children’s with the Reading Power program in South Carolina. This program initiated her interest in Nantucket Lighthouse School whose mission she applauds. “You recognize each child individually and spur them onto greatness. I am proud and honored to have been asked to join your board.”
