Ollila was born to
Finnish parents in Gratiot Location,
Houghton County, Michigan, a copper-mining company town in the
Upper Peninsula. At the time, Gratiot was a rough-and-tumble place where drinking was the "main problem." Ollila became an outstanding athlete on the
Calumet High School football and track teams and was devoted to hunting, trapping, and heavy machinery. During his high school years, Ollila experienced a religious conversion under the mentoring of Pastor Charles Hart of the First Baptist Church of Calumet. After graduating from high school in 1961, Ollila worked in the logging industry and as a tree topper; but moving to Detroit, he "surrendered his life…to be a preacher." Following his future wife to
Bob Jones University, he overcame a speech impediment and gained the respect of his work supervisors as a hard worker and natural leader. Ollila served as an interim minister at a Baptist mission church in an area of Greenville known as Bootleg Corner. After graduation, he became youth pastor at Calvary Baptist Church,
Roseville, Michigan (1968–75), where he proved to be charismatic youth counselor and evangelist. He later served as an evangelist with Life Action Ministries. In 1984, having impressed inventor and businessman, Paul Patz (1911–2000), the founder of
Northland Baptist Bible College,
Dunbar, Wisconsin, Ollila was offered the presidency of the small school. During his term of office (1984–2002), the school grew from 125 to over 600 students. In 2013, Ollila began "Building Great Leaders," a "ministry emphasizing servant leadership to pastors, churches, colleges and other Christian ministries both in the U.S. and overseas." ==Books==
