Our Staff

God’s Work. Our Hands.

God doesn’t need our good works, but our neighbor does. As Lutherans, we are called to use our lives to do God’s work in the world by sharing the wonders of God’s grace with others. Lutherans are known for their outreach programs. 1 in 50 Americans plus many others around the world receive help from the Lutheran church. It could be as simple as tutoring a child in an after-school program, or as complex as working with governments to eradicate hunger throughout the world. In many and various ways, every day members of Trinity are making the world a better place.
