Derek was raised south of Custer City and attended Custer City Schools until 1994 when they consolidated with Thomas and Fay where he graduated in 1996.

Derek worked at the Burns Flat Coop after graduating college before becoming employed by Western Equipment in Weatherford for the past 11 years. Derek adored his family and would move mountains to be there for them. Derek was a devout Christian man who loved to study and share the word of God. He recently was asked to lead an adult Sunday school class, which he was hesitant but felt it was God's calling to do so. Derek so loved his children and he never thought he would be sporting a cheer dad t-shirt but he did and was so proud to do so for his baby girl. Derek helped his son almost daily learn to play baseball, and the pride on his face to see him step onto the field was evident. Derek enjoyed being with is family whether just being at home, playing pool volleyball, attending an OU football game, traveling, going on vacations, snow skiing, farming and going to the lake with his family. Derek was a member of Kiwanis Club of Weatherford where he loved to serve and give back to the community.
