The only thing this family of companies has in common is the Duchossois family, the third-generation owners of The Duchossois Group, Inc.

The Chamberlain Group, a subsidiary, is the world's top maker of residential and commercial door openers and a leading maker of access control products. AMX performs systems integration, while other companies offer AV equipment, Internet-based access control, and lighting products. The Duchossois Group also owns an early-stage IT venture capital fund and holds a minority stake in horse racetrack Churchill Downs.

Geographic Reach

The Duchossois Group has operating facilities in more than 30 countries in North America, Asia, and Europe.


The Duchossois Group has leading brands in the residential security, lighting, and convenience products markets and the commercial control, automation, and digital media markets.

The company’s portfolio companies consist of The Chamberlain Group (residential and commercial access control products), Chamberlain Manufacturing Company (defense products); AMX (command, control and communications products); HeathCo (motion-activated lighting, door chimes and wireless lighting controls); Milestone AV Technologies (audio-visual mounting solutions and projection screens), Brivo (internet based access control systems); Duchossois Capital Partners (private equity); and Duchossois Technology Partners (early stage venture capital).

The Duchossois Group invests in company which have annual revenues  between $100 million to $500 million and EBIT of between $10 million to $75 million. It is seeking to add to and diversity its existing portfolio through complementary and strategic acquisitions and investments.

The Duchossois Group's current strategy is "lifestyle improvements for the home and office." To that end, it is looking to expand the company's existing portfolio of consumer goods, access control, and systems integration companies, as well as diversifying and adding firms that have niche products, strong management teams, and intellectual property. Its venture capital fund, Duchossois Technology Partners, focuses on acquiring communications, information technology, semiconductors, and software businesses.

The company believes it has a competitive edge based on its business philosophy.

Company Background

In 2011 its AMX unit acquired SchoolView Technologies, LLC., a Plano, Texas based company specializing in building comprehensive software that consolidates management and control of diverse school technologies at the district, building and classroom level, on a single, comprehensive platform. Through the acquisition AMX sought to address the issues of lower funding and higher demand for innovative use of technology without increasing costs or compromising technology.

The Duchossois Group was founded in 1916 as a small freight car repair shop.
