John was known throughout his life as a loyal and dependable man. He loved a good cup of coffee and meaningful conversation with those he cherished most. Gifted with his hands, John could fix nearly anything and worked hard his entire life. He deeply loved his country and was proud of his military service. Never too proud to admit when he was wrong, John lived with humility and a strong faith, always relying on Jesus as his guide. Together, he and Connie made a wonderful team. John would often say with pride, “I’m a Veteran.”
