Providing our clients with quality materials and mobile crushing solutions
In 1975, Bob Nannini started his own construction company with the hopes of one day expanding. His “one man band,” with a mere three pieces of excavating equipment, has now grown into Callahan and Nannini Quarry, a family owned and operated business spanning multiple generations. The principle that guides our company’s growth remains constant: hard work equals customer satisfaction.
Calling with one of the most unique requests we’ve heard, Honeybee Robotics contacted us seeking a place to test their latest creation – a drill with the capability of traveling to Mars. The production, which took place in late 2001, was truly an experience and caught the eye of local media.
