Liberty Bank in Middletown recently closed on its acquisition of Naugatuck Valley Financial Corp. and its subsidiary bank Naugatuck Valley Savings and Loan.

The merger closed at the end of business last Friday, Jan. 15, and it brings Liberty Bank up to $4.5 billion in consolidated assets, $3.4 billion in deposits, $3.3 billion in loans and $610 million in total capital.

“We are very pleased to welcome the Naugatuck Valley Savings and Loan customers to Liberty Bank,” President and CEO Chandler J. Howard said in a statement. “Liberty Bank is committed to providing exceptional customer service and quality products to meet the needs of the consumers, businesses and the communities which we serve. This merger will offer an expanded line of products and services to Naugatuck Valley Savings and Loan customers, and greater convenience to all our customers through our expanded network of 56 banking branches.

All of the former Naugatuck Valley Savings and Loan branches will operate under Liberty Bank’s name, with the exception of its location on Highland Avenue in Cheshire. That branch has been closed, as Liberty Bank already has a branch at 160 Highland Ave.
