There, he spent many years as Plant Manager, then as the Director of North Dakota Generation. John was appreciated for his kind and respectful leadership, inspiring others to work together to succeed. He enjoyed providing personal tours of the plant, always with a twinkle in his eye, to many family members, grandchildren and friends.
