Steve Tinsley
Clerk
Steve grew up in the military, traveling around the world. He followed in his father’s footsteps in serving our country through a long and distinguished career in the United States Navy. After retiring from the military, he entered the private sector for a few years before starting his second career as a missionary. During those years, he was active in the Officers’ Christian Fellowship, a parachurch organization whose mission is to engage military leaders in biblical fellowship and growth to equip them for Christlike service. Joan used her musical gifts to serve the Lord in local churches and pursued a personal desire to study Russian, little realizing how God would use both her singing and her Russian in later years. Steve and Joan joined Kontakt Mission, where they served for many years as missionaries in Orenburg, Russia. Steve used his gifts in teaching, and Joan used her voice to impact many young people for Christ and to help plant a church deep in the heart of Russia. After leaving Russia, they continue to serve in member care for Kontakt Mission, traveling to visit missionaries around the world to encourage them in the work of the Lord. Steve and Joan live in Cape Elizabeth, Maine, and are active members of Galilee Baptist Church. They enjoy spending time with their four children and numerous grandchildren.
