Lisa M. Stewart, who has 25 years of experience in real estate on Martha's Vineyard and previously established Lighthouse Proerties, will join Sandpiper Realty as an associate broker.

Lighthouse will continue to service 2016 summer rentals, and staff members have transitioned to new professional positions.

“Sandpiper Realty is a firm I have long known and admired,” Ms. Stewart said in a press release. “It was time for me to focus more on my client relationships and be relieved of the administrative and management load.”

Ms. Stewart is the former head coach of the high school girls varsity basketball team. She lives in Oak Bluffs with her husband Bruce; they have two college-age children.
