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.

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.
