There were very few things he couldn’t fix whether it was plumbing, electrical, vehicles, or building something - he could figure it out. He was an avid hunter and fisherman and loved spending time with friends and family in the great outdoors. His life was certainly never boring or dull. His curiosity and knowledge gave him a broad spectrum of interests which inspired him to achieve great things. Greg so enjoyed teaching himself to play his guitar and writing songs then sharing them with others. He had a great sense of humor that he used to lift all around him. He loved to teach and was extremely gifted at it. His students always loved him and he could make even the most boring subject interesting. He loved to work and always had to have a project going that he could work on or tinker with. Greg loved outdoor activities such as hunting, fishing, boating, camping, and riding motorcycles and 4-wheelers. He, also, enjoyed gardening and home improvement projects.\r\n\r\nIt is said that angels cry when we leave heaven to come to earth and then cry for joy upon our return. We are certain that there will be a great celebration in heaven for him. All those who have passed before will be waiting with open arms to greet him upon his return He will be missed more than words can express by those who are left behind We grieve upon losing him and our hearts are heavy but we are grateful to have been a part of his life. He touched the hearts of so many. Greg was preceded in death by his parents, son Kyle and brother-in-law Charles Thayer.\r\n\r\nThe family would like to thank all the nurses and caregivers from Summit Home Health and Hospice, especially Noemi and Hector, for their kind, loving and compassionate service to Greg in his final days.\r\n\r\nA viewing will be held at Jenkins-Soffe Mortuary, 1007 W.
