Andrew C. Tuecke, CFP®
Drew was introduced to Jesus Christ in the summer of 1990 in his hometown of Marion, Iowa. His older sister invited him to a local Baptist church, where he first heard the Gospel. That summer marked the beginning of Drew’s life in Christ. Upon returning to college at the University of Northern Iowa, he connected with a group of young men at a newly planted assembly near campus. After graduating with a bachelor’s degree in finance, Drew packed up and set out to study the Bible for three years at Bob Jones University (BJU).
In 1994 while at BJU, Drew met Beth (Schoeppe), and the next year, they were married at North Ridge Bible Chapel in Raleigh, North Carolina. Shortly after, they moved to Dubuque, Iowa, where Drew served as a Trust Officer at Believers Stewardship Services for over 20 years. During this time, Drew and Beth raised and homeschooled their six children—three sons and three daughters.
Today, they live outside Cedar Rapids, Iowa, enjoying their growing number of grandchildren. Alongside his role as an operating owner of Stewards Advisory Services, Drew also manages a small sheep farm on 15 acres of pasture and woodland surrounding the family home.
Drew serves as an elder at Cedar Rapids Bible Chapel, where he ministers through preaching, counseling believers, and evangelizing in the community.

Robert C. Sullivan
Rob has a heart for the advancement of the Gospel around the world. This is in large part owing to the influence of Bethany Chapel (Yonkers, New York) on his life. At the age of 11, he came to know Christ as his Savior while attending Daily Vacation Bible School at Bethany Chapel in Yonkers. Shortly thereafter, he joined the meeting and has been in fellowship ever since, also serving as an elder.
In 2019, Rob married Susie Henderson. Prior to their marriage Susie was a professor of elementary education at Emmaus Bible College. The two are dedicated to ministry and often travel when Rob speaks at assemblies/conferences and Susie speaks at ladies conferences. Rob sits on a number of boards in various capacities, including serving as board chairman for Christian Missions in Many Lands, Associates for Biblical Research, and School Ministries.
Rob is a graduate of Emmaus Bible College (Biblical Studies) and the University of Notre Dame (Finance and Business Economics). From 1996 through 2014, he worked at Morgan Stanley, achieving the title of Executive Director. Rob left Morgan Stanley at the end of 2014 to join the staff of Believers Stewardship Services (today known as Legacy Ministry Services) where he serves as President.
