In September 2000, Jason and his family would relocate to Tacoma, Washington. He then moved back to South Dakota, where he would attend Timberlake Elementary School. He continued to attend Timberlake School even after moving to the country near Whitehorse in 2005. In 2008, Jason and his family moved to Mobridge, where he met his best friends–Eric, Donte, Sam, and Killian–at Mobridge Junior High School. In 2010, he moved to Rock Creek and attended McIntosh High School until his senior year. He transferred to McLaughlin High School his last year and graduated from there in 2015.

After high school, Jason held various jobs. In 2019, he worked at Prairie Knights Casino, where he would meet Marissa Kills In Water. Jason then started working at Grand River Casino as a Dealer and later as a Pit Boss. In 2021, he reunited with Marissa. In June of that following year, his favorite person came into the world, his son Atreus. Jason continued working at Grand River Casino until his passing in 2026.

Jason engaged in various hobbies throughout his life. When his friends were around, he would run around town skating and taking part in many adventures. Family time was often spent playing Yahtzee, going on long road trips, and gambling. He spent much of his time with Atreus teaching him to play video games, watching cartoons, and being the best dad in the world. In his alone time, he would read, listen to music, and draw. He thoroughly enjoyed interacting with customers and coworkers at his job.
