Les Ollila

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."

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.

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.

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."

Leslie John Ollila (born March 22, 1943) is an evangelist who served as the second president (1984-2002) and then chancellor (2002-2013) of Northland Baptist Bible College (1976-2015), later Northland International University.
