R.K. Castillo began traveling as a Missionary/Evangelist when he was 18 years old. For over a decade he ministered to crowds in stadiums around the world. This brought him to every continent (except Antarctica) where he was able to not only lead people to Jesus but train up local believers to find their part in God's plan to transform the nations. After nearly ten years pastoring a church among the homeless in Waikiki, Hawaii, he moved to Paraguay to help pioneer YWAM Asunción. Today he serves as the Training Director, equipping young people to share the gospel, heal the sick, and disciple the nations.
