Founded in March of 1983, the Massachusetts Sheriffs’ Association (MSA) supports, promotes, and advocates for each of the 14 Sheriffs' Offices in the Commonwealth. The MSA facilitates cooperative and collaborative relationships among the Sheriffs for the purpose of developing standardized training, reporting, providing governance over shared projects, discussing operational best practices, and providing research and data on matters of mutual interest and concern. The MSA improves public safety by promoting greater understanding of issues impacting the Massachusetts Sheriffs and by bringing together law enforcement and criminal justice professionals.
