About us

Desert Witness is an international music and evangelism ministry founded by Sam and Jessica Cyiza — husband and wife, united in marriage and mission — with one aim: to point hearts to Jesus Christ through music and scripture.

We partner with churches and conferences to provide music, concerts, divine service programs, and evangelism seminars. We minister to congregations of all sizes across the United States, bringing Christ-centered messages of hope for worship services, evangelistic events, conventions, and retreats.

We don’t just perform — we disciple. Every platform we stand on ends with a three-part appeal: for those ready to surrender to Christ for the first time, for those who need spiritual revival, and for those who desire to recommit their lives entirely to God.

Desert Witness works with the Arizona Conference and partners with its ministerial department in reaching underserved remote churches across the conference. Our reach extends well beyond the local church, spanning conferences, unions, and the North American Division.

Desert Witness has also been featured on the Holy Spirit Broadcast Network (HSBN), a Christian television network reaching over 86 million viewers across 135 countries.
