High Adventure Ministries began serving in the Middle East in the early 1970s. 

Founder George Otis was one of the first evangelical leaders to realize the significance of Israel's role in the end times, and the importance of the church's relationship to God's chosen people.

As Chief Executive officer of High Adventure Ministries, Jacqueline Yockey has expanded the reach of the ministry into Africa, Iraq, Afghanistan, Haiti, Indonesia, and many other countries who are in desperate need of the message of Jesus Christ.
