Chamberlain Manufacturing Corporation

  • Overview

The only thing this family of companies has in common is the Duchossois family, the third-generation owners of The Duchossois Group, Inc. The holding company, pronounced "deshy-swa," focuses its investment interests in the consumer products, technology and services sectors. 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.


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

Other portfolio companies include Milestone AV Technologies (audio visual mounting equipment and metal racks); Brivo (Internet control systems); and HeathCo (motion-activated lighting and door chimes). 

Geographic Reach

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


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. It holds a purchased company for a longer period than most strategic buyers; it tries to preserve the culture and staff of the companies it acquires; it is able to provide operating resources; and it allows sellers to remain invested in their businesses.

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 acquisiton AMX is looking to address the issues of lower funding and higher demand for innovative use of technologywithout increasing costs or compromising technology.

Company Background

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