Our Story
TSL has served the Watertown community since 1977 providing a Christ-centered education focused on Excellence. The continuing purpose of Trinity-St. Luke’s Lutheran School is to serve as a tool for the Holy Spirit to “…make disciples of all nations." TSL prepares children to live lives that “thank and praise, serve and obey Him,” and assists parents in the spiritual training of their children.
In 2024 the mission of TSL expanded to include TSL Roots Early Learning Center. This early childhood ministry aids TSL in serving the families in our community with very young children.
