Joe Fedorko


After completing the GE Apprenticeship, Joe founded Diversified Manufacturing Systems and has guided the company's growth for over 30 years. He serves as the company's chief engineer and still takes time to train and mentor new machinists. He applies that hands-on approach throughout operations, and while he leads the business from the head office, he still keeps an eye on how parts are packed, QC procedures, and all customer relations to maintain the highest standards at every stage of the business. Though serious about performance, he's as likely to crack a joke on the shop floor as he is to spot check parts.
