His early civilian career included several engineering positions in the utility industry in New York and on Plum Island.

Michael began his association with the Shelter Island Library as a volunteer consultant to the Board during the lower level renovation where he evaluated the building’s energy usage, analyzed the adequacy of the HVAC system, and made several recommendations for improving the building’s energy efficiency. Since joining the Board, he developed a Risk Management Plan and recently chaired the committee that developed the Library’s 5-year Strategic Plan.

Michael and Trish, his wife of 46 years first came to Shelter Island in 1987 and after years of weekends and vacations on the island, bought a home in South Ferry Hills in 2002. They became full-time residents in 2015. Their home is often filled with the joyous chaos of their three daughters and families, including their six grandchildren.


William G. Martens has been a Shelter Island homeowner since 2001. After retiring from a distinguished career in international banking, he now makes his home here and in Darien, Connecticut, where he spends the winter. His familiarity and affection for the East End reach back to his and his wife’s grandparents, both of whom bought homes in Sag Harbor in the 1920s. His four children and many grandchildren love visiting him and his wife, Virginia, a retired English Teacher. William and Jini share a passion for travel, read voraciously and are avid book group members.

A native of Chatham, New Jersey, William is a graduate of Dartmouth College and served in the U.S. Navy for four years as an officer on a destroyer.
