Organized in 1957, the Darien Chamber of Commerce (COC) supports the business community and quality of life in Darien. The COC is a non-profit business, which relies on membership dues for financial support.
There are a number of ways the COC works with its members to better the business community. These include: providing legal information and networking opportunities, promoting and broadening awareness of Darien's business community, and the coordination of the sidewalk sales. The Chamber also works with the citizens of Darien to address their requests for specific products or services.
The Darien COC President is Carol Wilder-Tamme.
