It is with bitter sweetness that we say an earthly goodbye to Kay Halladay Peterson. We’re certain that she had a joyous reunion on the other side with her son, her parents, her brothers, sister and many other family and friends. She passed away peacefully after lingering health issues.\n\nKay was born on March 14, 1937 to Wilford Meeks and Vilate Jacobson Halladay while they were serving a mission in Gilmer, Texas. She spent her childhood in Provo, Lake Shore and Spanish Fork graduating from Spanish Fork High School. She continued her education at BYU earning a BS degree in Medical Technology and later a MS degree from the University of Utah in the same field.\n\nShe married her eternal companion Robert Lynn Peterson in the Manti temple on August 2, 1958. Together they recently celebrated their 65th wedding anniversary. During their life together they lived in Olympia, WA, Salt Lake City and then to their home in Pleasant Grove, Utah. She worked in many hospital settings in the Salt Lake area in laboratory medicine. In 1975 she began teaching clinical microbiology at BYU. She loved her students, remaining in friendships with many of them until the time of her passing. She taught at BYU for many years and then for a short time at the University of Utah and then to Red Cross. \n\nKay and Lynn served faithfully in many church callings through the years. Their favorite calling being that of Mount Timpanogos Utah Temple service in the Baptistry where they served for 11 years. Temple service was always a priority throughout their lives together. \n\nKay loved to cook and bake. So many friends and family have been the beneficiaries of her special “treats”! Her love of baking will live on through her daughter and granddaughters. She was a talented seamstress and loved to read. Kay and Lynn were avid BYU fans braving the traffic to travel to many, many football and basketball games. She was a huge cheerleader for her grandchildren and great-grandchildren. 22 years of baseball, softball, basketball, volleyball, soccer, wrestling and dance performances. Her cheering voice will be sorely missed.\n\nKay and Lynn were blessed with 2 children, 8 grandchildren and 21 ½ great-grandchildren. She was fiercely devoted to this posterity. Her life was spent serving them in too many ways to count. We all knew of her testimony, devotion and love to the gospel, to our Savior Jesus Christ, and to our Heavenly Parents. We await our happy and bright reunion with her. \n\nShe is survived by her sweetheart Lynn Peterson, daughter Keri (Tracy) Byington, daughter-in-law Star Peterson, grandchildren Lindsie (Scott) Giles, Joey Byington, Taylor (Elora) Byington, Andy (Anna) Byington, Alex (Kale) Darling, Rylan Peterson, Zach (Syd) Peterson and Peyton Peterson.
