Nasco was started in 1941 by a vocational agriculture teacher. He developed several teaching aids to use in his vocational agriculture classes…teaching aids that were not readily available from any other source. This simple act of filling a classroom need with an appropriate product was to become a way of life for Nasco in years to come.
Located in Fort Atkinson, Wisconsin, Nasco is comprised of a central office, warehouse facilities, production facility (biologicals and educational kits), and plastics manufacturing plant.
