The Downtown Owners Association was established in 1982 by a group of
property owners who recognized the need for an organized group to
protect their interests in downtown San Antonio.
DTOA was a principle partner with the City of San Antonio and VIA in the TriParty Project streetscape improvements, and created a public improvement district to pay for the private property owners' participation in the successful effort.
In 1994, the membership restructured the organization, broadening their involvement and the categories of
membership to become the Downtown Alliance. In 2013, the name was changed to Centro Alliance, which is part of the family of organizations of Centro San Antonio.
The Alliance is composed of major property and business owners in the downtown area, and others who also are committed to downtown's revitalization.
