Philip Dwyer officially assumed his duties as the interim chief executive officer of the Westport Weston Family Y on Monday.

Dwyer takes the helm from Rob Reeves, who announced his resignation on Oct. 20 after a six-year tenure overseeing the planning and construction of the Y's $38.5 million complex on its 32-acre Mahackeno campus. The 54,000-square-foot complex, known officially as the Bedford Family Center, opened to members early this month.

"I'm very excited about the future of our Y and know that this changing of the guard will be seamless under Phil's direction," Reeves told a meeting of Y staff directors Monday morning, according to a press release from the Y. The meeting was also attended by Dwyer and Bonnie Strittmatter, president of the Y's Board of Directors.

Reeves will remain an active Y member and will assist with the executive transition through the end of the year, according to the release.

Dwyer, retired CEO of the Central Connecticut Coast YMCA and current chairman of the Board of Education in Fairfield, will lead the organization until a permanent replacement is named. That process, which will be overseen by the Y's Board of Directors in consultation with executives from Y-USA, is expected to take about six months.

"I came to the Y at the age of 9, and I've never left," Dwyer told the Y staff.

"We extend ourselves to the community in whatever way we can. We're here to serve," said Dwyer. "If the community asks, then there's a need, and it's up to us to make it happen."
