About Us - Omicron Delta


Omicron Delta - Today

Omicron Delta is a virtual chapter that supports members across the globe. Due to our size and geographical nature, the chapter hosts at least one meeting online each year so any member may attend.  Additionally the chapter holds one or two education conferences per year.  The location of these events is different each time in an attempt to involve as many members as possible.  New member inductions are often held one to two times per year in locations where there is a nursing campus with the University of Phoenix.  The chapter also hosts one virtual induction each year.  

Due to limitations to be able to meet face to face, members of Omicron Delta are encouraged to get involved in the chapter through one of our member events or by joining n discussions that are being held by the chapter through social media such as STTI's The Circle. 


Sigma Theta Tau was founded in 1922 by six nurses at Indiana University. The founders chose the name from the initials of three Greek words: 'storage,' meaning love, 'tharos,' meaning courage, and 'tima,' meaning honor--sigma, theta, tau. In 1985 the society was incorporated as Sigma Theta Tau International Honor Society of Nursing, a not-for-profit organization with 501(c)(3) status. The mission of STTI and its chapters is to provide leadership and scholarship in nursing practice, education, and research to enhance the health of all people and to support the learning and professional development of its members who strive to improve nursing care worldwide. STTI's vision is to create a global community of nurses who lead using scholarship, knowledge, and technology to improve the health of the world's people.

In 1995 the University of Phoenix Nursing Honor Society was formed by Dr. Ela-Joy Lehrman who served as President, and 166 members were inducted. The Chapter received its charter and Greek name--Omicron Delta--from STTI on April 3, 1998, and it has grown to over 5000 active members. The Chapter has been actively involved in numerous community activities as well as national research conferences.
