Meet The Team

Austin worked 5 years in church ministry before joining Navigator staff in 2023. After working on 3 different college campuses, he feels strongly that there is no more influential time in students' lives than on campus. Austin believes that ministry happens in the context of relationship.  He has been married to his wife Ashley for six years. They have two beautiful children.

Ashley is on part-time staff with the Navigators. Before having kids, she was an English-second-language teacher. Ashley is passionate about mentoring women.  She loves spending time with her family, reading, and being in nature.
