Sep 16, 1952 - Oct 28, 2022


Mark John Steinbruecker was born to Glenn and Joyce (Zerger) Steinbruecker on September 16, 1952 in Sheboygan, Wisconsin. He went home to his Lord and Savior on Friday October 28th, 2022 in Sugar Land, Texas, his home since 1992. On October 12, 1952 he became a child of God through his baptism at St. Paul’s Lutheran Church, Sheboygan, Wisconsin. On May 29, 1966 he confirmed those baptismal vows through the Rite of Confirmation at Good Shepherd Lutheran Church in Sheboygan.
Mark attended Sheboygan schools and graduated from South High School in 1970. He went on to earn a Bachelor of Science degree in Business Administration in 1974 from Valparaiso University in Valparaiso, Indiana.

Mark is survived by his daughter Katherine Bustos and son-in-law Aaron Bustos, Houston, Texas.

Mark is also survived by his sister Lisa Steinbruecker and her husband Michael Shallue of Kohler, Wisconsin, as well as his former spouse Susan R. Steinbruecker of Sugar Land, Texas. He was preceded in death by his mother and father Joyce and Glenn Steinbruecker and his grandparents.
