Woodrow Kroll served as President and Senior Bible Teacher of the international radio ministry Back to the Bible for 23 years and he has authored more than 50 books. He has traveled to all 7 continents and 112 countries and everywhere he's gone, he's met untrained pastors. Pastors faithfully serving the Lord, but who have no opportunity to have any formal training.

In 2013, God led Wood to take his 50 years of experience and create the HELIOS Projects. Woodrow Kroll Ministries provides this teaching on Helios units to untrained pastors who have little hope of getting formal Bible training any other way.

In 2018, following his father’s retirement, Timothy Kroll answered God’s call and accepted the position of President for the ministry. Tim has served in the pastorate for over 23 years, having served as the Senior Pastor of Northside Baptist Church (St. Petersburg, FL) for 13 years, Senior Associate Pastor at Northside for 3 years and the Missions Pastor at Heritage Baptist Church (Lynchburg, VA) for 7 years. Tim’s passion is to become like Jesus – the goal of a disciple of Jesus Christ. This includes knowing the words of Christ, carrying on the ministry of Christ, imitating the life of Christ and helping others to do the same. It is this pastoral experience and heart that God is using in Tim to see His good blessings come to other pastors around the world.
