Aztalan Engineering

Our History

Our company is built upon a foundation of leadership and commitment. Our founder, Jim Brey, started his venture in leadership by enlisting in the Army infantry after graduating from high school, where he served as a mortar observer and was promoted to Staff Sergeant in his first year. He served in the Korean War where he earned a field commission to Second Lieutenant. When he returned home he discovered aviation, and he served out the remainder of his military career as a pilot of both fixed-wing planes and helicopters, retiring as a Major.

Jim graduated from the University of Wisconsin School of Engineering with a degree in mechanical engineering and spent the next 19 years as a mechanical engineer with McDonnell-Douglas, AC Delco, and Hamlin Electronics. But, Jim had a dream to own his own company, so in July, 1978, Aztalan Engineering was incorporated as an engineering and manufacturing company. Housed in Jim’s two-car garage with two part-time employees, a few Bridgeport’s and a Macintosh computer, under Jim’s leadership, Aztalan Engineering grew rapidly, and within a decade moved to a new 30,000 square foot facility in the Lake Mills Business Park.

Today we’ve expanded even further, but remain faithful to our foundation of leadership and committment. No client, no part, no problem and no opportunity is too small to escape our undivided attention – and our commitment to excellence and the needs and welfare of our customers is legendary.

Aztalan Engineering is an Employee Owned Stock Ownership Plan (ESOP) Company. An ESOP is similar to a 401(k) retirement plan but where the investments are primarily made in company stock. Aztalan Engineering’s ESOP was formed in 2009 and became a 100% ESOP company in 2014. Employees of AEI have the opportunity to become stakeholders and grow their percentage vested based on their years of service.
