Where we serve

Jesus has called my wife, Shelby and I into our fifth year as missionaries. This next year we will continue to serve the students at Colorado State University. In our five years as a FOCUS missionaries in Colorado, we have developed an insatiable desire to lead the other Missionaries on our campus and work with the students that God has placed in our path on and outside of campus. What our world desperately needs is people who love Christ and His Church. Servant leaders who are willing to lay down their life for others. We truly believe that the work of FOCUS on college campuses across our country will have a major impact on the future of our nation. 

Our Story

I grew up in Crofton, NE and attended the University of Nebraska in Lincoln. After graduating, I married my best friend, Shelby, and we now have two daughters, Josie and Gemma. I became a missionary alongside my wife in 2013 and through our work with FOCUS, Shelby and I have had the privilege to see so many lives changed, so many students decide to start a relationship with Christ, study His Word, return to the Church, make a good Confession, begin to ask deep questions about the purpose of their lives, and become fully alive in Christ. 

As a missionaries, our greatest desire is to lead all students to Christ. Our life has been transformed by Jesus and we want nothing more than to bring this joy to others and introduce them to the life-changing message of the Gospel. It is a great joy to minister to college students as a family, inviting them into our lives led by Christ.

Your Impact

Blessed Mother Teresa says, "Some give by going and others go by giving." When we answered the call to join FOCUS, we made the decision to rely on the spiritual and financial support of mission partners to join us in this mission. We've been blessed with the most amazing people who have journeyed with us as we serve on campus. If you are interested in partnering with us, please let us know of the best way to reach you and we will schedule an appointment. We'd be honored to share this mission with you. Jesus is doing amazing things through our work here in Colorado and it would be a great pleasure to welcome you on mission with us!
