He was part owner in a private consulting firm and worked with many companies in the United States, Europe, Singapore and Australia. His career culminated in a six-year stint living in Montpellier, France, retiring in 2003.

David was a member of First Baptist Church in Sister Bay, where he served as Chairman of the Board of Elders, Chairman of the Missions Committee, and as Director of Bridges of Friendship to International Students for 11 years. He also served on various Boards for Christian ministries, including a homeless shelter, Lazarous House in St. Charles, IL, World Evangelical Fellowship, Mission Chad, and Impact France.  

On August 26, 1960, he married Joyce R. Felten in Sheboygan, Wisconsin. They met while Joyce was attending Wheaton College in Illinois. He is survived by his wife Joyce, two daughters, Christine Lace (Mike), Lisa M, and a son, Jonathan (Lisa J.), six grandchildren: Aimee, Matthew and Katey Lace, and Dane, Evan, and Benjamin Detert, and a brother Douglas Detert (Millie), and two nieces, Rebecca Engstrom (Steve) and Anna Marie Detert.
