Justin Christopher Michael Mattingly entered eternal rest on September 21, 2025, at the age of 36.

A 2007 graduate of Sapulpa High School, Justin was a gifted artist with a true talent for drawing. He was kindhearted, creative, and enjoyed many passions throughout his life, including art, fishing, four-wheeling, motorcycles, and spending time with his friends. Known for his warm smile and loyal nature, he was affectionately called "Smiley" by those closest to him. Though a bit stubborn at times, that quality often gave him strength when he needed it most. Above all, Justin loved his two dogs, Dude and Bowser, who were like children to him.

He is lovingly remembered by his mother, Cindy; his brothers and sisters—Amanda, brother-in-law, Tim, James, Nick, Joe, Jordan, Ashley and Lisa; his brother-in-law, Jimmy; and his nieces and nephews—Ace, Reese, Evan, Alex, Julius, Aylan, and Jimmi-Girl. He was preceded in death by his sister, Angelina, and his nephew, Cash.

A Celebration of Life Service for Justin will be held at 2:00 PM on Saturday, October 4, at Mobley-Groesbeck Funeral Service in Sand Springs, Oklahoma.
