Dr. Casey Leighton Thomas, DVM

Dr. Casey Leighton Thomas, DVM, born August 7, 1955, to William and Marjorie Thomas, passed away on April 24, 2026, surrounded by the love of his family.

Casey was a devoted husband, father, grandfather, and man of faith whose life was defined by love, service, and compassion for both animals and others. He was preceded in death by his beloved wife, Joyce Thomas, whom he married on June 11, 1982. Casey adored Joyce and the life they built together, and after her passing, he continued to live with purpose and love, especially for his family.

He is survived by his daughter, Natalie Rasco (maiden name Thomas), and his son-in-law, Bryce Rasco, whose love, devotion, and care meant so much to Casey and his family. Casey was a proud and deeply devoted “Pa” to his grandchildren—Grayson, Aubree, Madelyn, and Olivia (Libby)—who meant the world to him and brought him immense joy.

Casey dedicated over three decades of his life to veterinary medicine, practicing in Junction City, Kansas, from 1984 to 2014 as the owner of Flint Hills Veterinary Hospital, which he and his wife Joyce proudly ran together. He was exceptional at what he did and had a genuine love for animals of all kinds. Always eager to learn, Casey expanded his care to include exotic animals and even served the animals at the Milford Nature Center. His passion for wildlife and animals left a legacy, especially in his grandson Grayson, whom he taught to fish, identify snakes, and appreciate the natural world.

He was deeply involved in his community, including his work with Fort Riley, and faithfully served as a deacon at First Christian Church in Junction City, Kansas. His faith in Jesus was a steady and guiding presence in his life.

Casey also valued health and discipline. He loved to exercise and took pride in staying physically fit throughout his life—though he never outgrew his well-known sweet tooth. He will also be remembered for his quick wit, playful sense of humor, and the practical jokes he loved playing on family and friends.

In 2014, Casey and Joyce moved to Texas to be closer to their daughter and her family. Those years spent near his grandchildren were among his most cherished.

Casey bravely battled Parkinson’s disease for many years, facing it with strength, resilience, and a positive spirit. He remained committed to his health and found encouragement and friendship through Rock Steady Boxing, where he built meaningful relationships and a strong support system.

Casey will be deeply missed by all who knew and loved him. His family finds comfort in knowing he is now in heaven, reunited with the love of his life and with Jesus. His legacy lives on in the lives he touched, the family he cherished, and the love he gave so freely.

A small celebration of life for close family and friends will be held on May 12, 2026. The family sincerely appreciates the love, prayers, and condolences of all who knew and loved Casey.
