When founder, John Marusiak Jr. first read about Electrical Discharge Machining in 1955, he knew it was the future for manufacturing. A retired Air Force fighter and test pilot with plenty of energy - John, along with his wife - Angie, incorporated Micro-Tronics in December of 1968. Initially running machines during the morning, visiting customers and making deliveries in the afternoon, John nurtured Micro-Tronics' growth in specialized machining

Over the years, their dedication, drive and customer emphasis evolved Micro-Tronics into one of the finest advanced high technology precision machine shops in the Southwest.

MTI combines these capabilities by also manufacturing complex assemblies consisting of rubber and/or composite materials bonded to machined hardware.

Over the course of time, John and Angie's children have joined their parents and expanded the operations to include not only Conventional EDM, but computerized Wire EDM, CNC EDM, Rubber Molding, and Production Machining in an impressive and clean multi-building campus in Tempe, Arizona. The latest growth oriented step forward is the opening of our newest building, adding an additional 17,000 square feet of work area, in fall of 2008. An additional building will be raised on an adjacent lot, which will bring the total square footage to over 100,000 square feet.

On April 19, 2000 - John Marusiak officially stepped down as President and C.E.O. of Micro-Tronics. We thank John for his unselfish, tireless efforts that built Micro-Tronics into the successful company it has become. He will remain as a consultant for an indefinite period of time. The board of directors elected Robert, "Bob" Marusiak as the new C.E.O.

Photographs only show you a small part of our facilities and capabilities. What they don't adequately show is the pride we take in our ability to master difficult projects and our commitment to quality. We think our record speaks for itself - customers keep coming back to us with their toughest problems to solve.
