We strive to make quality parts, on-time, at a competitive price, while always striving for continual improvement.

Glen-Mac Swiss was founded in 1960 by Glen MacGregor as a Swiss type screw machine shop with just 12 Swiss screw machines. The company was sold to its present owners, The Postajian Family in 1979. The Postajian's expanded the company by purchasing 15 multi-spindle screw machines, 12 more Swiss screw machines and 3 CNC machines.

The secondary operation's department was expanded also and an assembly line was added.

The Postajians expanded the Quality Control of the company to meet the requirements and continually improving to keep up with today's high demand quality requirements.

The Postajian's vision is constantly at work and allows Glen-Mac Swiss Company to grow and compete in the CNC market; while also continuing to improve and grow in the screw machine market as well.
