About Theta Omicron Chapter
Theta Omicron was founded on February 13, 1966 at University of Texas/Rio Grande Valley in Edinburg, TX. We've been around 54 years and going strong!

National History
Delta Zeta Sorority was founded at Miami University in Oxford, Ohio. These outstanding women were not even given the full status as students until 1902. When six young women came together to form a social sorority, they had a vision of a lifetime sisterhood fostered by ideals that they cherished. These friends bonded quickly as they faced the challenges of starting a sorority on the male-dominated campus that was known as the “Mother of Fraternities.”

Our six founders, Alfa Lloyd, Mary Collins, Anna Keen, Julia Bishop, Mabelle Minton, and Anne Simmons met with the then-president of the University, Dr. Guy Potter Benton. During their meeting, they put their words into actions and created the sorority they had dreamed about and in fact created the first sorority at Miami University.

Once they received the Articles of Incorporation from the State of Ohio on October 24th, it has been known to Delta Zeta as our Founder's Day. The Founders then went on to lay the foundation for the sorority, which would have a nation reach.

Today, Delta Zeta has enriched the lives of over 260,000 alumnae and collegiate members in the United States and Canada.

Zoom + Sisters = Zisterhood

Zoom meetings would not be as fun, if it weren’t for our sisters.

Our Philanthropy

We raise funds through HEART FOR HEARING AND SPEECH

Our members know how to care. We simply created a program to channel their compassion and direct their energies toward a shared ideal – make life better for others. Heart for Hearing and Speech is the theme for our personal philanthropy and chapter events designed to raise money and awareness in support of our philanthropy partners who are making a difference the world over.

Starkey Hearing Foundation

In 2015, Delta Zeta named Starkey Hearing Foundation our National Philanthropy Partner in an effort to extend our impact throughout the world. We pledged to raise $5 million over the next five years for hearing and speech, and to donate that amount to Starkey Hearing Foundation. In 2020, Delta Zeta successfully completed the pledge! Since the partnership began, Delta Zeta has raised over $5.5 million dollars for Starkey!


We raise awareness
Heart for Hearing and Speech Day coincides with the start of Better Hearing and Speech Month in May, which is a national effort to raise awareness about communications disorders and the need for improved global hearing health. We spend the first Tuesday in May telling our friends and family about the world’s most prevalent chronic health condition and asking for their support in addressing it.

Seriousfun Children’s Network

As our Global Service Project, SeriousFun’s mission is to create opportunities for children and their families to reach beyond serious illness and discover joy, confidence and a new world of possibilities, always free of charge.

American Society for Deaf Children

To broaden our domestic impact through awareness and education and provide more ways for members to connect with our philanthropy, in 2020 Delta Zeta announced a partnership with the American Society for Deaf Children.
