Buck spent the first 15 years of his life on a farm in Missouri, but moved to Wichita, Kansas, where he graduated from high school and from Wichita State University. He married his college sweetheart, Lynn Trombold, and was married to her for 47 years before losing her to a four-year battle with cancer. After they were married, Buck went back to school and received his MA in Christian Education from Wheaton College. A few years later he earned his D.Min from Drew Theological Seminary. In the meantime, he and Lynn produced seven tricycle motors (aka kids). He and Lynn realized that it was easier to produce them than to raise them. Nevertheless, they realized that each child was a wonderful gift from God and they thoroughly enjoyed being parents. Buck served as a Young Life staff person in Wichita, Dallas and Seattle for several years. He also taught high school and coached for five years in Dallas and Wichita. His next move was to become a youth director at a Presbyterian church because they offered him more money. He likes to claim that he became an"Economic Presbyterian." They moved to Houston First Presbyterian Church in 1984 where he became the Director of Christian Education. He was with the group which broke away from First Pres in 1991 to plant CEPC. Shortly after the formation of CEPC, Buck became ordained in the EPC, and in 1993 he moved to Katy to pastor Cornerstone EPC for 11 years. He retired from the pulpit, but not from the ministry. He came back to CEPC in 2004 as Associate Pastor but retired from full-time work when his wife became ill. Buck has continued to work part-time and very much enjoys being involved with the church family at CEPC. He currently has 21 grandkids. Buck is engaged to be married November 11, 2017, to Diane Mayne, who lives in Burton, Texas. He and Diane met on one of Buck's bicycle trips.
