Oasis is led by a leadership team of seven lay leaders and a pastor. The leaders are committed Christian men and women from around the world, with different denominational backgrounds and a deeply held common faith in Jesus Christ as Lord. Each member of the leadership team is committed to serving the body of Christ in Amman through the congregation at Oasis Church.

John holds an M.Div. and a Th.M. in Church History from Gordon-Conwell Theological Seminary and a B.S. from Georgetown University. He has lived in Jordan, the U.S., South Sudan, South Africa, and Japan.
