Rev. Kevin Lester

Associate Pastor/
Sanctuary Campus Pastor

Rev. Kevin Lester is the campus pastor at our Sanctuary site and has been appointed by the UMC as pastor of that community since 2021. In 2023, he was appointed Associate Pastor for St. Mark’s when Sanctuary and St. Mark’s UMCs merged to become one church. His lifelong dream is to create ways for people to encounter God, so they can enjoy shalom, gratitude and wonder. He works with our outreach and justice ministries since he is always thinking about people in our community who haven’t had this kind of experience with God at church. He loves long board games, loud music, deep conversations, noisy babies, and how bookstores smell. His wife and his son make his heart grow three sizes.
