Nyamira West Field was officially organized and launched in 2020 by Dr. Blasius Ruguri, President of the East-Central Africa Division (ECD), in the presence of Dr. Samuel Makori, President of the East Kenya Union Conference (EKUC). This landmark occasion marked a significant milestone in the church's commitment to enhancing mission effectiveness and administrative efficiency within its territory. Since its establishment, the field has experienced steady growth in membership, church development, and community outreach initiatives.
