John A. Carroll, the former chief operating officer at East Boston Savings Bank, has been named president and CEO of Winchester Savings Bank. He replaces Peter Segerstrom, who has retired after working at the bank for 43 years.

“After an extensive search, the hiring committee found John to be the ideal candidate,” Deborah Carson, chairman of Winchester Savings Banks’ board of trustees, said in a statement. “His in-depth knowledge of community banking, decades of operational experience, and visionary leadership make him a natural fit for the role and a wonderful asset for Winchester Savings and our customers. At the same time, I’d like to recognize and thank our outgoing President and CEO, Peter Segerstrom, for his service and dedication to the Bank over the past 43 years. We all wish him nothing but the best in retirement.”

Carroll spent 10 years as executive vice president and COO at East Boston Savings Bank, which was acquired in November by Rockland Trust Co. Carroll also worked for more than seven years at Danversbank, which was acquired by People’s United Bank in 2011.

“I’m honored and excited to take the reins of an institution that truly lives up to its promises of strength, service, and community,” Carroll said in the statement. “I recognize the big shoes I’ll be filling, and I look forward to helping shape the future of Winchester Savings. This institution has been around for 150 years, and that is a testament to our customers and our people. My focus will be on continuing that long legacy of excellence.”

Winchester Savings Bank is a mutual bank with about $600 million in assets and four branches in Winchester, Woburn and Arlington.
