Greg was preceded in death by his parents, Jay and Virginia Johnston and his brothers, Robert and Randy Johnston.
He is survived by his children, Shannon (Jeff) Sullivan, Brandie Sellers, Judilynn (Richard) Barnes, Cheyenne (Blake) Terry, Jenny (Tanner) Glass, and any others that viewed him as a father figure; his grandchildren, Wesley, Cody, Laken, Wayne, Dustin, Bryan, Rain, Jozlyn, RJ, Bryan Jr., Dakota, Aubbrie, Sarah, Chloe, William, Andrew, Avery, Tate; his brother, Richard (Pat) Johnston; his sisters, Renee Wood and Mary Johnston; his great-grandchildren, and a host of nieces and nephews.
Greg was a talented mechanic and a jack of all trades – if he didn’t know how to fix it, he would figure it out. He was also known for his carpentry skills. He would help others before helping himself. He loved his grandchildren and enjoyed spontaneous road trips with no particular destination.
