Before his term, he was city councilor for Ward 2 and worked for Buzzards Bay National Estuary Program in toxics reduction. After leaving office, he led the Parents Alliance for Catholic Education, earned degrees in law and public policy, guest lectured at local universities, volunteered at the city's Polish church and took on the role of register of deeds for Bristol County's southern district in 2017. His brother, Michael Kalisz, shared the news in a Facebook post that brought hundreds of comments in just a few hours, many of which recalled personal memories with the former mayor. "Fred was just such a remarkable man, a remarkable brother, a caring son, a loving husband and father," said Michael Kalisz, 57. "He was always there whatever the need and tried to do whatever he could for whoever it was... It feels so unfair he was taken away before we could enjoy more time together."
