The late 60’s was a time in American history where segregation existed, even in federally funded programs.  In San Antonio, there were no social services for the elderly Blacks.  As a result, Delores Bradley introduced to Alpha Tau Omega the idea of doing something for as many of this age group as possible in a more tangible way and on a broader scale.  The chapter voted in favor of sponsoring such a project.  As a result of the recommendation made and proposal written by Delores Bradley, funds were allocated from the Economic Opportunities Development Corporation (EODC) of San Antonio and Bexar County.    The funds were awarded in June 1966, to Alpha Tau Omega chapter for the operation of the Eastside Senior Citizens Project located at 715 South Rosary Street.

The services of this center were made available to persons 60 years of age and older whose income indicated that they were within the poverty index, with the purpose of maintaining, supporting, and enhancing the physical, social, emotional and economic well-being of senior citizens.

In 1970, when the Roseville Apartments were constructed, chapter members wanted to extend the services developed and implemented from the Eastside Senior Citizens Project to the senior citizens residing at Roseville.  The original proposal did not allow the extensions to other areas in the city. 

In order to more adequately provide support services for the residents of Roseville and the surrounding community of senior citizens, Alpha Tau Omega Senior Opportunities Services of Texas Incorporated (ATO-SOS) was created as a 501(c)3 in January of 1971 and incorporated on March 15, 1973.  ATO-SOS was able to provide the following services; health care, a day care center, counseling and referrals, social and recreational activities, religious and civic activities, telephone assurance, and transportation.

Over the years quantity of services changed, but the quality of services provided did not.  In 1998, due to the increasing cost of maintaining transportation and a decreased in federal funds, ATO-SOS discontinued this service which led to a loss in part-time employees and a full time Director.  This caused a change in the structure of ATO-SOS.  Board members updated the by-laws, and established an Advisory Council made up of residents of Roseville, members from the San Antonio community and the ATO-SOS board.  ATO-SOS with the financial help and support from Alpha Tau Omega chapter became a self-sufficient functioning board.
