A 107 Year History in Chicago
The West Central Association - Chamber of Commerce (WCA) is dedicated to enhancing the well-being of its member businesses, institutions, and organizations.
Since 1918, the WCA has advocated for business and property owners on legislation, taxation, transportation, architectural treatment and model plans for the area.
The Chamber’s growing membership works together to encourage a healthy business environment by providing a unified voice for our members, supporting thoughtful development, encouraging mutual support, and attracting new businesses, institutions, and residents to the area. WCA is a City of Chicago Delegate Agency and sole service provider for Greektown Special Service Area #16.
We are a representative in the community for the Department of Planning and Development and offer one stop shopping for City programs to help start or grow your business. Please contact us today.

Thank you for an amazing year as we celebrate 2025 successes: record networking attendance (over 400), the new Business Builder education series, member growth, successful fundraisers (Beers & Bites), community events (Madison Row Fest, West Loop Art Festival), and its role as the SSA #16 service provider for Greektown. Plans for 2026 include expanding Business Builder, introducing new networking formats, launching new member tiers/benefits, and debuting an online member portal. Your member involvement is crucial for the future vision and we look forward to collaborating in 2026.
