Nantucket Cottage Hospital is a not-for-profit regional medical center located in Nantucket, Massachusetts and is the only hospital on the island. Founded in 1911 and conceived by the visions of Dr. John S. Grouard and Dr. Benjamin Sharp. The original small Cottage Hospital on West Chester Street grew apace with the island community's needs. In 1957, the hospital opened new facilities at its current site, 57 Prospect Street. In the 1960s, when that building was deemed too small, a wing was added to accommodate the growing need for comprehensive medical care. In 2006, the hospital became an affiliate of Massachusetts General Hospital.[1] A brand new 106,000 square foot hospital building completely replaced the 1957 facility in 2019. Thanks to an unprecedented $120 million capital campaign, the largest in Nantucket history, the new hospital was built entirely through private donations, debt-free, and with no taxpayer dollars.[2] The chairman of the Board of Trustees is Craig Muhlhauser, the hospital CEO is Amy E. Lee.[3]
