Thomas White, the long-time leader of Rockland Federal Credit Union, plans to retire next year.

White has been RFCU’s president and CEO since 1994. The credit union said in a statement that White would retire on May 31.

RFCU has about $2.5 billion in assets and is the state’s third-largest credit union behind Digital Federal Credit Union and Metro Credit Union.

“Tom’s retirement is the culmination of a distinguished credit union career, including almost 30-years as the leader of our organization,” RFCU said in the statement. “During his tenure RFCU became one of the most successful credit unions in the Northeast serving more than 200,000 members in Eastern Massachusetts.”

The credit union’s board of directors has started a search for White’s successor and has hired an executive recruiting firm to assist with the search, the statement said. White will continue to lead the organization during the search and will have a role in the transition to new leadership.

“While Tom’s retirement represents the fulfillment of his personal life plan, the organization will miss his leadership and dedication,” the statement said. “Thankfully he will leave behind a legacy of success, a strong leadership team, and 190 dedicated employees who can carry on the work of serving our members and fulfilling our mission statement.”
