Jason A. Graves

July 28, 1999 — August 27, 2023

Grand Junction, Colorado and Lee's Summit

Jason Allen Graves, 24, of Grand Junction, Colorado, formerly of Lee’s Summit, Missouri, was born July 28th, 1999, to Roger A. and Kathryn D. (Miller) Graves. He departed this life Sunday, August 27th, 2023, after summiting Ganette Peak, in Fremont County, Wyoming. 

Jason had recently left a job he loved at Teton Science School (TSS) to start his new life with his girlfriend Kasey Ervin in Grand Junction, Colorado. Jason returned to Wyoming to say goodbye to a place near to his heart; sadly he fell while descending the summit. Jason was a cautious, experienced and accomplished mountain climber, having summited 30+ 14K foot mountains in Colorado, all of the Grand Tetons in Wyoming, and Mt. Hood in Oregon. Jason loved open water swimming and standup paddle boarding on mountain lakes. He especially enjoyed his group of pickup basketball friends. Jason lived a full life and gave and received joy every day. 

Jason graduated from Lee’s Summit High School in 2018 and attended the University of Missouri and Longview Community College. Jason participated in basketball and swimming in high school, culminating in three state swimming medals and earning All State Honors his senior year. The spring of 2020 Jason started his mountain adventure in Estes Park then Winter Park, both in Colorado. He returned home for a short period before leaving for Jackson, Wyoming and Grand Teton National Park to work at TSS. He enjoyed his time living in Colorado; Wilson, Wyoming; and Victor, Idaho and made friends wherever life took him. He also completed the Kansas City Marathon in October 2021. 

He met Kasey (our daughter-in-law, Bailey’s roommate) at University of Missouri in 2018; their friendship continued to grow after Jason left for the mountains, and they became a couple shortly after Bailey and Eric’s wedding in June 2022. Within a few weeks they made plans to start their lives together, which they had just begun when Jason passed. It was a storybook romance that we were all happy to see. Kasey was great for Jason! Our hearts break for Kasey and all she’s lost. 

Jason was preceded in death by his paternal grandparents, Ed and Fern Graves of Strasburg, Missouri, and his maternal grandmother, Jean Miller of Lee’s Summit. 

He is survived by his partner, Kasey Ervin of Grand Junction; his parents, Roger and Kathy Graves of Lee’s Summit; his brother and sister-in-law, Eric and Bailey Graves of Indianapolis, Indiana; many aunts, uncles and cousins, all who love him dearly; and a host of many friends.

After Kasey, his family, and outdoor adventures, Jason loved the Chiefs and Patrick Mahomes. In honor of Jason, the family encouraged visitation and funeral attendees to wear Chiefs gear.

Visitation was held Wednesday, September 6, 2023, at the Grace United Methodist Church, Lee's Summit.

Funeral services were held Thursday, September 7, 2023, at the Grace United Methodist Church. Reverend David Hackett officiated. Interment was in the Strasburg Cemetery, Strasburg, Missouri.  Casket bearers were Eric Graves, Brad Graves, Chad Payne, Cameron Payne, Royse Miller, Chase Kozar, Jordan Ben-Hanania and Ian O'Brien. Honorary casket bearers were Lindsey Graves and Renetta Kinny.

In lieu of flowers, the family requests donations to the Jason Graves GoFundMe, the proceeds to be used to establish a scholarship in Jason’s name at the Teton Science School and to help Kasey start her life without Jason.
