A Bain Capital executive is now on the board of directors at Eastern Bank.

The company yesterday appointed Greg A. Shell, managing director of the Bain Capital Double Impact Fund to the board, as well as a member of the bank’s board of trustees.

Shell has been a member of Eastern’s board of corporators since 2011 and is currently on the bank’s Investment Advisory and Trustee-Corporator Nominating committees.

He also leads the Investment Committee for the Business Equity Fund, which Eastern recently launched in partnership with the Boston Foundation.

“For more than 200 years, Eastern has been dedicated to strong financial returns and measurable social good in communities across Greater Boston and beyond,” Shell said in a statement. “I am honored to join Eastern’s board of directors and look forward to continuing to advance Eastern’s work and mission.”

Prior to joining Bain Capital, Shell was a portfolio manager at Grantham, Mayo, Van Otterloo, and before that a senior equity analyst in the global equity research group at Columbia Management Group. Shell is involved with many business and civic organizations, including the Boston Foundation, the Boys & Girls Clubs of Boston, Massachusetts General Hospital and MassChallenge.

“We are delighted to have Greg join Eastern’s board of directors,” Deborah Jackson, lead director of Eastern Bank, said in a statement. “He operates at the nexus of economics and local and world events, and pivots easily among finance, philanthropy and other sectors. We look forward to continuing to benefit from his many insights.”

“Over the past seven years, Greg has been a terrific thought partner who has had an increasingly significant impact upon Eastern within multiple dimensions of our work,” Bob Rivers, chairman and CEO of Eastern Bank, said in a statement. “He is one of the most thoughtful contributors in Greater Boston’s business and philanthropic communities with the professional experience and deep community engagement that make him an excellent addition to our board.”
