Posie Constable

Posie Constable has island living in her blood. She is a twelfth-generation descendant of Hawaiian natives and Boston missionaries to the Hawaiian Islands. Posie grew up on Oahu, loving the ocean, but also spending endless afternoons getting her hands dirty while trailing both grandmothers around their gardens.

After spending a year abroad in Kobe, Japan and graduating from the University of Colorado, Posie earned an MBA and settled into a successful finance career in Manhattan. She finished a 30-year investment banking run as a Managing Director in Debt Capital Markets at Merrill Lynch before transitioning to the not-for-profit world.

Posie spent the past eight years as Director of Business Development in the nation’s first municipal green bank, the New York City Energy Efficiency Corporation. Working with local governments, community leaders, clean energy non-profits, as well as building owners, managers and contractors, Posie helped to fund all manner of clean energy projects, helping clients increase energy efficiency and reduce carbon emissions.

Posie joined her husband’s family in Nantucket beginning in mid-1980’s, and has been here for every season since then, finally buying a home in 2012. She is a past board member of Nantucket Community Sailing, served as co-chair of Nantucket Race Week in 2012, and currently sits on their Advisory Board. She is a former governor of the Nantucket Yacht Club, and served on the Town’s Neighborhood First Advisory Committee.

An avid sailor and kiteboarder, Posie and her husband Bobby Constable are also fond of the bees in their four hives and riding motorcycles to new places across the US and beyond.
