Clare De Graaf is a follower of Jesus, an elder, a Bible teacher, and for more than thirty years a full-time spiritual mentor of men, from college students to other would-be servant/leaders. A successful businessman and Christian all his life, at age thirty-one he found himself at a spiritual crossroads – a crisis of faith triggered by cancer. Surrendering himself to Christ, he sold his manufacturing company in 1984, at age thirty-five, to devote the balance of his life serving wherever God called.

Since then, De Graaf has been deeply involved in US and international church planting, microeconomic development in Haiti, and orphanage and hospital reconstruction in Albania. He is also the founding chairman of DOOR International, a ministry committed to translating the Bible into sign language for the Deaf of the world. In 2013, Clare’s book, The 10 Second Rule was published by Simon and Schuster (Howard Books).

Clare and his wife, Susan life in Grand Rapids, Michigan, and are the parents of six children and proud grandparents of twenty.
