Jonathan has worked as a speaker with Stand to Reason since 2019. A former atheist, Jonathan used to think belief in God was unwarranted and irresponsible. Then, after examining the evidence for Christianity he was faced with the fact that Jesus is who He says He is and the Christian worldview tells the true story of reality. Since then Jon has been passionate about engaging the culture with honest, well thought-out reasons why people should trust the Christian worldview. Jon has developed a series of passionate talks to do just that.
In 2013 Jonathan earned a master’s degree in Christian Apologetics from Biola University, graduating with honors. Jon brings a unique perspective to his audiences and the Stand to Reason team, having more than ten years' experience in the legal field and serving more than five as a pastor in his local church.

Tripp Almon serves as the Outpost Coordinator and a speaker with Stand to Reason. He is from Newnan, Georgia (just south of Atlanta) and now lives in Colorado with his wife, Megan, and their kids. Tripp’s passion for educating students of all ages in the areas of Christian theology, worldview, and apologetics is driven in large part from growing up in a Christian home and then struggling profoundly with the tidal wave of cultural ideas that engulfed him as he entered a secular university. Thankfully, his experience taught him that Christianity not only stands in the marketplace of ideas — it soars.
Before joining Stand to Reason in 2025, Tripp, a former elite gymnast, coached gymnastics for more than two decades. He served as a pastor for 10 years and was the Director of the Summit Ministries Gap Year program for seven years. Tripp loves when he and his wife, Megan, get to speak and serve at events together.
Megan Almon, a former University of Georgia gymnast, worked as an award-winning journalist until 2008, when she decided to pursue a career speaking and teaching about Christian apologetics — especially in the areas of pro-life apologetics, bioethics and aesthetics. She joined Life Training Institute in 2009 and was awarded an M.A. in Christian apologetics from Biola University in 2011. She worked with Scott Klusendorf at Life Training Institute until 2024 when she began working with the speaking team at Apologetics, Inc. In 2025, she started an exciting new chapter as a Stand to Reason speaker.
