Citizens Bank in Hartford celebrated its 100th anniversary this afternoon by grilling for customers. Bank President Colleen Lewis says her great grandfather helped start the bank in 1914 and her family has always owned it. The bank became a member of the Federal Reserve in 1933. "Several of our customers we've served for several generations obviously when you cover 100 years. We have a few people left who knew my grandpa Riley who died in 1953, " said Colleen Lewis.
