Born on December 31, 1995, Jon grew into a man defined by his profound sense of duty to his country, family, and the people he loved.  A proud United States Air Force veteran, Jon served with honor and distinction in Air Traffic Control. His commitment to service continued after his military career, working for the Department of War with the Air Force USAFE in Germany, again in Air Traffic Control. Whether in uniform or as a civilian, Jon approached his work with dedication, precision, and a deep respect for those who served alongside him.

Jon embraced life with curiosity and enthusiasm. He loved traveling the world, exploring new places, experiencing different cultures, and visiting historical sites. He had a special passion for cars, especially Volkswagens, and more recently, his Audis. Above all, he loved being a father. His greatest joy was spending time with his daughter, helping on the farm, or relaxing by a campfire. Jon carried a natural warmth into every room he entered, his charm and kindness leaving a lasting impression on everyone who knew him.

Jon is survived by his beloved daughter, Erin Taylor Sisson; his parents, Aaron and Kerri Delp; and his brothers, Jarod Lamont and Levi Delp; Tom and Georgina young, Shirley Gradert, Roger Delp, Chris (Sisson) Ohrt, Heather Oliver, Lloyd Oliver, Kelan and Tonya Wells, Erik and Shrhonda Delp, James and Brianna Lamont, Joe Sisson, Matt and Grace Sisson, many beloved cousins, nieces, and nephews.

We will forever cherish his memory and carry forward the values he lived by - dedication, kindness, and devotion to something greater than himself.

Jonathan was preceded in death by his grandfather’s, Jerry Sisson and Louis Oliver.

He will be deeply missed and forever remembered.
