Thomas "TJ" Arnstad

At just 43 years old, TJ left an indelible mark on the world as a man who gave his heart fully to those he loved. Words alone cannot express the pain our family is feeling right now. Our hearts are broken. Words cannot begin to describe the profound depth of this loss, which is felt by so many. TJ's passing leaves an unimaginable void in our lives and the lives of those who loved him—a space that could only be filled by his unique spirit and presence.

Born (and raised) in Loveland, Colorado, on November 28th, 1982, TJ was the son of Jolene (King) and Charles Arnstad. He was a man of grit and intelligence—a hard worker who never gave up. Whether he was turning a wrench as a mechanic for Anheuser-Busch or lending his talents to real estate and remodeling, he approached every task with a dependable spirit.

On May 6, 2016, TJ married Dayna Lewis in Fort Collins, Colorado. Together, they built a life centered on their two children, Kenneth Leighton and Arrya Linda. TJ was a father who would have done anything for his kids; they were his greatest pride.

TJ was often the "glue" that held his people together. Witty, fun-loving, and fiercely loyal, he found joy in the simple things: a good car, a round of golf, a day on the slopes snowboarding, or playing video games. He loved deeply, worked hard, and was a true friend to many.

He leaves behind his wife, Dayna, and his children, Kenneth and Arrya. TJ is also survived by his dad, Chuck Arnstad and his mom, Jolene Eheart; his brothers, Steven Arnstad and Travis Elijah; and his sisters, Felicia Hernandez and Kelsey Wright. He is preceded in death by his step-dad Kenneth Eheart, who was like a second father to TJ. He will be profoundly missed by his family and all who were lucky enough to call him a friend.

A Celebration of TJ's Life will held from 12pm-5pm on Saturday, February 21st, 2026 at the Venue at 319 in Loveland.
