The Voice and Advocates for Business in our community The Weslaco Area Chamber of Commerce was established in 1935. We are a business organization consisting of local businesses, organizations, professionals and individuals. The Chamber is not a civic club, charitable organization or department of government. We’re a private, nonprofit entity. The strength of the Chamber lies in attracting the greatest number of members, creating a pool of resources for ideas, energy and finances. It is a coalition committed to building a healthy economy and improving the quality of life within the local community.
