Greg was selected as an NAIA academic all-American in 1981.

He was instrumental in transitioning the Ninth Grade Center into a grades nine through 12 high school with its own activities and sports teams. Sheyenne fully became a high school in 2015, with the first senior class graduating in 2016. Greg is a lasting legacy and he will be remembered as the guide and architect of the exciting, but difficult, transition from one high school to two high schools,”Flowers said. “It was obvious in watching him work that he loved his job, loved West Fargo Public Schools and loved kids. He will be missed.”
