1960's
The 1960's were active and rewarding years for Theta. Within the biennium of '61-'63, '63-'65, and '67-'69 Theta received national recognition for being one of the "Top Ten" Chapters. In March of 1964, Theta and Upsilon hosted the District VII Convention on the campus of the University of Cincinnati. In 1969, the two chapters of Theta and Upsilon established the Delta Epsilon chapter at Miami University in Oxford, Ohio.
1970's
In 1979, Cindy Claypool and Sandy Drake founded the Cincinnati Alumni Association.
1980's
At the District VII Convention hosted by Michigan State University in April of 1980, Theta was awarded the TBΣ Chapter Participation Award for bringing the greatest number of members the farthest distance. During the spring of 1981, Theta installed the Zeta Rho chapter at Kentucky State University and the Zeta Sigma chapter at Xavier University. After months of hard work by chairpersons Robin Roush Bierschenk, Paul Wesolowski, and Louis Barone, and members of Theta and Upsilon, the University of Cincinnati hosted the 1981 National Convention, from August 2 to 7, 1981. A few years later, in 1984, Theta established the Eta Eta Chapter at Central State University.
The '80's ended with one of the most rewarding years Theta has experienced; 1989 was a true "banner year." It began as both Theta and Upsilon were nominated as "Top Ten" Chapters in the Nation for the biennium of '87-'89. At the 1989 North Central District Convention, Theta and Upsilon were awarded the Most Outstanding Display Award and the right to host the 1990 North Central District Convention. Theta also received the Counselor's Cup Award. At the 1989 National Convention hosted by Oklahoma State University, Theta and Upsilon received the J. Lee Burke Display Award for the most outstanding convention display. Also, in 1989, some alumni reformed the Alumni Association after several years of being inactive.
