USA Southwest

The Tsaile Church is located in the heart of Navajoland in northeast Arizona. The church has an effective ministry to the Dine’ (Navajo) College campus. Everett & Mary Teller are the first Native American pastors of the church. Hooghan Nizhoni Church is located on the Navajo Reservation between Window Rock, AZ and Gallup, NM. John & Toni Thumma began their pastoral ministry there in August 2006 and John is currently the Senior Pastor.

The Gamerco Church of God is on the north side of Gallup, NM. This multi-cultural congregation is financially self-supporting. John Thumma also serves as the Senior Pastor of this congregation and is assisted by Jacob & Haley Day.

Each year, work teams from various churches throughout the CGGC visit and serve at Tsaile, Hooghan Nizhoni, and Gamerco, providing assistance with construction projects and Vacation Bible Schools.
