We are Sophisticated Women of Sigma Gamma Rho Sorority, Inc.  The Oak Park chapter, Theta Chi Sigma (TCS), answered the call by being chartered on Saturday, March 6, 1999, in Oak Park, IL by 30 professional women.  This eclectic pool of women with an array of talents set community service goals to better serve the westside of Chicago and the surrounding communities and Sigma Gamma Rho Sorority, Inc. In only a short time, TCS has developed civic, social, educational, and economic programs within the community with an emphasis on the positive development of women and their families.
