Upon his Honorable Discharge in 1970, John continued classes at the University of Nebraska at Omaha focusing in Biology.
John’s love of science and discovery lead him to a Botany course where he met his greatest love, Diana Krogstrand.
They were married in Omaha on Jan. 24, 1970, and remained there until hearing of a high school position in Nebraska City.
