For 25 years, Dr. Tim LaHaye pastored one of the nation's outstanding churches in San Diego, Calif., which grew to three locations. It was during this time he also founded two accredited Christian high schools, a school system of 10 Christian schools, San Diego Christian College (formerly Christian Heritage College), and assisted Dr. Henry Morris in the founding of the Institute for Creation Research, the nation's foremost exponent of creationist materials.

Tim LaHaye has written more than 50 non-fiction books on a wide range of subjects such as: family life, temperaments, sexual adjustment, Bible prophecy, the will of God, Jesus Christ, and secular humanism with over 13 million in print, some of which have been translated into thirty-two foreign languages. His writings are best noted for their easy-to-understand and scripturally based application of biblical principles that assist in facing and handling the challenges of life. He designed the LaHaye Temperament Analysis that has been used by over 30,000 people; many have found it to be a life-changing tool for self-improvement.

LaHaye and his wife Beverly, who is chairman of the board and founder of Concerned Women for America, have been married for over 55 years and live in southern California. They have four grown children, nine grandchildren, and seven great grandchildren.
