Meet Our Staff


Pastor Leslie O’Callaghan

Lead Pastor

Originally from the plains of northeastern Colorado, Pastor Leslie has enjoyed meeting the people of God all over the country. A 2004 grad of Concordia University River Forest and Lutheran Theological Southern Seminary (2011) in South Carolina, she served her first call in Sacramento, CA after serving as a chaplain for a large Lutheran school in Florida. In 2017 she moved back to Colorado where she served as Assistant to the Bishop for Faith Formation and Candidacy in the Rocky Mountain Synod. She is delighted to join the pastoral staff at Saint Andrew and looks forward to getting to know the congregation and what excited them about following Jesus in these bizarre days.  Pr Leslie enjoys coffee, her piano and banjo, reading, learning new hobbies without really mastering them, and anything JRR Tolkien related.

Pastor Leslie and her spouse Asher live in Marathon with their pup Francis and three cats, Agnes, Tillie, and Jack. They love the outdoors and are excited to explore this area of Wisconsin, especially when water is involved.

Pastor Jeff Martinson

Visitation Pastor

I am grateful to be part of the ministry team at Saint Andrew. It is a great blessing to share your faith and life stories as I have been privileged to do as a pastor for over 30 years. I see that as an amazing grace. I am also an occasional on-call hospital chaplain in which it is humbling to share in God’s care and compassion.
