Sam Hart, Islands regional director at the Trustees of Reservations, will leave his position to start a new job at the Martha’s Vineyard Regional High School, Mr. Hart confirmed Tuesday.

Mr. Hart said his last day at the Trustees would be July 30.

“It was a tough decision, because I really enjoyed my time at the Trustees,” he said. “But for my family and me, it’s the right decision.”

Born on Martha’s Vineyard and educated at the regional high school, Mr. Hart previously served as the executive director of ACE MV, an adult higher education program based at the high school. Prior to his role with ACE MV, Mr. Hart had worked with human rights groups at the United Nations in New York city. He returned to the Island in 2011.

Mr. Hart was hired to head the Trustees Island operation in May of 2019, taking over after the departure of Eunice Yeomans.

The Trustees Islands director oversees Trustees properties on Martha’s Vineyard and Nantucket, including Menemsha Hills Reservation in Chilmark and miles of pristine, sandy shoreline around Cape Pogue Wildlife Refuge and Wasque Reservation on Chappaquiddick.

A nonprofit land conservancy, the Trustees of Reservations own and manage land, estates and properties throughout Massachusetts, including eight properties on the Vineyard.

Speaking by phone Thursday, Mr. Hart said he would be working for the high school in an administrative role for special projects, specifically workforce development. Mr. Hart, who has one child, said another was on the way.

He expressed enthusiasm about the transition.

“I’m very excited to be joining the high school for workforce development,” Mr. Hart said. “That has been a passion of mine for years.”

In a statement sent by email Tuesday, the Trustees praised Mr. Hart for his work.

“We congratulate Sam Hart on his new role at the regional high school. We will miss him at The Trustees,” said Christine Morin, chief of places and engagement at the Trustees.

“For the last two years, Sam Hart has played a critical role in advancing our mission on the Islands during a critical time. His knowledge of this community, commitment to preserving special Island places and sharing the beauty of the island with others and his positive attitude has been invaluable.”

Meanwhile, an interim will be named and a search will begin for Mr. Hart’s replacement, the statement said.

Mr. Hart said he would be available to assist the Trustees in the transition as they seek a new regional director.

According to high school principal Sara Dingledy, Mr. Hart’s official role will be coordinator of pathways and special projects. In an email to staff, Ms. Dingledy said Mr. Hart would support the high schools’ technical education program, forge partnerships with the community and help develop alternate pathways to graduation for students.

He is expected to start at the end of August, according to Ms. Dingledy.

In a brief phone interview, Ms. Dingledy said the decision to hire Mr. Hart came after the departure of assistant principal and CTE director Barbara-Jean Chauvin.

“While Sam’s hiring isn’t a direct fit into what Barbara-Jean had been doing, we’re excited because Sam can bring a lot of capacity to these roles.”

Ms. Dingledy added on the phone that Mr. Hart’s experience with the Trustees in facility management, and his role on the original high school building committee, would provide energy and leadership for the school’s upcoming building renovation project.

“Sam can really help lead with vision, and help guide the high school toward a renovation project in hopefully a couple of years,” she said.

Ms. Dingledy also said Mr. Hart’s hiring is one of more than a dozen staffing changes at the high school for the upcoming year, including new band, PE and special education teachers, a new nurse, Michael Savoy, a student intervention coordinator and the addition of an early childhood education teacher as part of the CTE program.

Although she said the role was administrative, Ms. Dingledy added that Mr. Hart would also be working closely with students.

“We’re going to build the role around him,” she said.
