In 1984, Carol Butler began the process of recruiting 12 registered nurses to form a chapter of Chi Eta Phi Sorority, in San Antonio, Texas. The National Organizer contacted the Regional Director, Soror Watkins, who in turn contacted Carol Butler and offered assistance from the two chapters in the region ( Zeta Chi and Rho Chi Chapters). On December 8, 1984, Theta Eta was chartered. In attendance were the Supreme Basileus Essie Rouser, the National Organizer, and members from Zeta Chi and Rho Chi Chapters. 

Charter members in 1984 were Carol Jean Butler (Organizer/Basileus), Charla Jean Hutchens, Margaret King, Kathleen Andrews Lindo (Epistoleus), Patricia Ann Osborn (Grammateus), Rosie Lee Palmore (Dean of Pledges), Vivian Whiteside Pankey (Tamias), Sharlene Elizabeth Prescott (Anti-Basileus), Elizabeth Jones Scott (Historian), Rochelle LaVerne Staten, Wanda Lee Sykes and Sheila D. Thomas (Tamiochous).

Our first line included Garletta Steen, Mary Horton, and Lieutenant Lucinda Gibbs. Our first National and Regional officer was Garletta Steen. Carol Butler was first to serve on the National Nominating Committee. Currently, we have over 60 active members and continues to grow.
