About Us

---

Mission 633 exists to make Jesus known in some of the hardest and most unreached places in the world.

Founded by Keith Mitzel and his wife Gayle, Mission 633 is driven by a deep conviction: the Gospel of the Kingdom is for every nation, every people group, and every heart — even where it comes at great personal cost.

Keith’s life is a living testimony of the redemptive power of Jesus. Having been rescued from a life of sin, and later walking through unimaginable loss after a tragic accident in 2014 that took the life of his son Sam, Keith encountered Jesus not only as Savior — but as Healer, Redeemer, and Restorer. Out of pain, God birthed purpose. Out of loss, a call to the nations.

Mission 633 (Formerly Keith Mitzel Ministries) was born from that call.

Mission 633 operates at the intersection of obedience, presence, and action.

We don’t simply preach the Gospel — we walk it out alongside people in real situations, real suffering, and real need. Our mission takes us into Muslim communities, persecuted regions, and places where Christianity is restricted or illegal.

We believe the Gospel is most powerful when it is both proclaimed and demonstrated.

Through mission trips, house visits, prayer, discipleship, and practical support, we step into lives and communities with the love of Jesus — trusting God to bring transformation.
