Clarence or Clay or “Coach” as many call him, was a teacher, coach, and Athletic Director for Marion Unit 2 for 35 years. He was a Marion Wildcat fan and watched, listened to, and read about Marion Athletics for 65 years.  As a football coach he helped build a winning dynasty at Marion High School.  The members of his undefeated team of 1963 were still in contact with him today.  In his role as Athletic Director, he was instrumental in establishing new sports at Marion High School and helped lead the way for girls’ sports in the 60s and 70s.  In the classroom, he provided his students with skills that they would be able to use for life.  Clarence, Clay, or Coach, he was a legend for Marion Wildcat Athletics.  His efforts did not stop at church, home, and work, he used his skills to help community efforts. He was always generous to people who seemed to be “down on their luck.” Clarence enjoyed teaching, coaching, building houses, woodworking jobs, repairs, sports, yard work, and many collections. For 63 years, he and his wife worked side-by-side to fulfill their dreams.  Besides raising six children and eight grandchildren, together they built or remodeled all of their children’s homes, and spent ten years restoring and preserving their historic Stotlar-De Mattei Home in Marion.  Clarence attended his children’s and grandchildren’s athletic events and other extra-curricular events without fail.  If there was not a local athletic event on a certain day, it was sure that he was watching it on television or listening on the radio. Clarence’s wife, children, grandchildren, and many beloved family, friends, and former students and athletes made his life fulfilling. He will be cherished and his legacy as a Christian, husband, father, grandfather, friend, and coach will live on.
