“Our lives are richer when we support one another” is Main Street Bank’s guiding principle. Wally firmly believes that the value our employees bring to a partnership with our customers has made us a strong community bank. From a customer’s first checking account to a financial plan that will carry them through their life and their family’s lives, Main Street Bank offers a commitment of stability, strength and exceptional customer service. Advice, options, assistance and a friendly approach are what come from having a banking relationship with us.

As CEO of Main Street Bank, Wally’s goal is to continue to develop the bank and all its employees to stay abreast of changes in both technology and the economy. Main Street Bank continues to serve our clients the way only a community bank can – as a financial partner for today and tomorrow, and a leader in guiding our customers and communities to solutions that serve their overall financial wellness.


Wally has been working within the banking industry since 1990. He has held many different roles starting as a Teller leading up to Senior Commercial Loan Officer at North Middlesex Savings Bank in 2010, and bank President and CEO thereafter. He took on the role as Chief Executive Officer of Main Street Bank at the beginning of 2019.


Wally has a long history of community service throughout his career.  He currently serves as Chairman for the Mount Wachusett Community College (MWCC) Foundation Board, on the Board of Directors for the Corridor 9/495 Regional Chamber of Commerce, and the Marlborough Economic Development Corporation.
