Family-owned ABCO has remained a Martin family business since its founding in 1972, when it began as a screw-machine shop in Ohio. After surviving an F4 tornado that destroyed its Blue Ash building in 1999, the company rebuilt in less than a week and continued expanding its precision CNC machining work. Now fully owned by Jason Martin, ABCO employs more than 30 people and serves customers with mid- to high-volume production from its Mainville facility.
