"The Simi Valley Chamber of Commerce promotes business in Simi Valley, through leadership, political action, and services to increase opportunities for our members" is The Chamber's mission statement, and for 50 years, The Chamber has provided these services to its members. The strength of The Chamber lies in its membership, which creates a pool of resources from which ideas, manpower, and support can be drawn. Members, consisting of small businesses, large companies, home-based businesses, and professional men and women, work together to enhance the quality of life in Simi Valley.

The Chamber functions as the headquarters for the business community by representing member businesses before government bodies and conducting joint promotional activities. It provides an opportunity for members to become directly involved in community issues and to express their views on developments that may affect their business. The Simi Valley Chamber of Commerce is the voice of business in the Simi Valley City Council, Sacramento and Washington, D.C.. Through our Government Review Council, we promote business interests at all levels of government.

Members who serve as Directors and on various committees are business people who volunteer because they believe in the effectiveness of The Chamber. Membership in The Chamber provides opportunities to become involved in areas such as economic development, networking, advertising and legislative representation.
