Ralph Drollinger, president and founder of Capitol Ministries, leads Bible studies every week on the Hill for U.S senators and representatives. He also leads a Bible study remotely for former White House Cabinet members and senior staff.

Capitol Ministries was founded by Drollinger and his wife Danielle in 1996 with the mission of making disciples of Jesus Christ in the political arena throughout the world. To date, the ministry has established Bible study ministries to legislators in 43 states, to city and county leaders in nine states and in dozens of foreign countries.

Drollinger played basketball at UCLA under coach John Wooden and was the first player in NCAA history to go to the Final Four four times. Drollinger was taken in the NBA draft three times but chose to forgo the NBA to play with Athletes in Action, an evangelistic basketball team that toured the world and preached the gospel at halftime. Drollinger signed with the Dallas Mavericks in 1980 as a free agent, becoming the first Maverick in the history of the franchise.
