Catherine Marie McClellan (Davison) went home to be with her Lord and Savior, on July 7, 2022, after a hard fought and courageous battle against cancer. Catherine was born May 27, 1970, in El Paso, Texas to Robert and Sharon Davison. She married Michael McClellan on April 23, 1994, and the two shared their homes, hearts, and lives with their loving and loyal pets. Catherine graduated from Rock Island High School, Illinois and completed her bachelor's degree at the University of Wisconsin-Madison. She received her master's and doctorate in marine ecology from Duke University in Raleigh, North Carolina. She did her post-doctoral fellowship at the University of Exeter in Cornwall, England. Catherine had a passion for environmental conservation and modeled a love for nature that will live on in those that knew her. Her research was centered on the behavior and conservation of sea turtles. Catherine knew Jesus as her personal savior and she walked in the spirit throughout her life as a testimony of His love. The simplest pleasures in life brought her the greatest joy. She loved the outdoors and quiet evenings at home with her husband and pets. Catherine was blessed to have visited and explored many amazing places throughout the world and found beauty in God's creation. Her heart was especially touched by the coastal region and people of Gabon, Africa, which hosts the largest leatherback sea turtle population in the world. She strove for excellence in her work and wanted to make a difference in the world of ecology and in the hearts of the people she met. In the past year, she was blessed to be part of a team that welcomed a wonderful Afghan refugee family to Wausau, and they quickly became just like family. She loved her family, friends, and animals with the same tenacity that she approached everything else in her life. Catherine will be missed by her loving husband Michael McClellan, her parents Robert Davison and Sharon Davison, her sister Lizabeth Bjarnarson, brother in-law Robert Bjarnarson, niece Jessica (Dan) Linehan, niece Rebecca (Chris) Arnesen, nephew Robert Bies, Angel (parrot), Polar (dog), aunts, uncles, cousins, friends and colleagues. She was preceded in death by her fur babies Spice, Sparky, and Tinker, and her brother-in-law Edward Bies.
