HSA Bank is a division of Webster Bank, N.A., Member FDIC, a subsidiary of Webster Financial Corporation.

HSA Bank began as the State Bank of Howards Grove, which opened in January 1913 in northern Sheboygan County. This rural, community bank would become HSA Bank decades later.

In 1997, State Bank of Howards Grove entered the consumer-driven healthcare market by providing MSAs.

In May 2002, the bank acquired approximately 7,000 accounts and $20 million in balances from Citizens Bank, which was in the process of merging Mellon Bank’s retail business.

State Bank of Howards Grove also began using the trade name MSA Bank in 2002.

After the advent of health savings accounts in 2004, MSA Bank redirected its energy and resources on HSAs and changed its name to HSA Bank.
