In 1986 a group of students felt that TKE would fill a void in the Saint Leo College Greek Community. That year the group of men received colony status. Through this group of men and many others hard work the Sigma –Theta Chapter of Tau Kappa Epsilon was established on September 16, 1989. In 1997 the Sigma – Theta Chapter of Saint Leo College closed do to issues still not specifically known. The Sigma-Theta chapter transitioned to a local fraternity named Sigma Chi Omega. The organization was short lived. The brothers decided to restructure their fraternity to symbolize something they believed in, and represented the values that they felt were important.
On February 29, 2000 Sigma Chi Omega fraternity transitioned to Kappa Lambda Local Fraternity. The colors chosen were Forest Green and Pearl White. The characteristics the organization based itself on were pride, dedication, and honesty. The symbols chosen were the sword, skull, and sledge hammer. The God chosen as the idol of Kappa Lambda was Thor, while the mascot chosen was the wolf. Kappa Lambda was the recipient of the SGU Fraternity of the Year award two years in a row but were named Greek Week Champions in 2000, 2001, 2002, and 2004.
In the spring semester of 2004 the active and new members of Kappa Lambda decided that although they were a great local fraternity there brotherhood would have stronger representation if they chose to transition back to their national roots as Tau Kappa Epsilon. With the help of Dr. Dadez, Vice President of Student Affairs, Kappa Lambda was able to meet with national representative Louie Correa. Following the presentation the brothers of Kappa Lambda voted unanimously to transition back to Tau Kappa Epsilon. Through the hard work of the active members of Kappa Lambda they were able to achieve a membership of 20 members and officially became the Sigma-Theta Colony of Tau Kappa Epsilon.
On January 9th 2005, the men of the Sigma – Theta Colony at Saint Leo University were initiated into the bond of Tau Kappa Epsilon. In February the Sigma – Theta took part in a successful formal recruitment hosted by IFC. The colony had the most men accept bids for new membership. In early April of 2005, the Sigma-Theta colony initiated 11 more men into the bond, bringing the chapter total to 30. Although they did not meet the 35 member requirement for a chapter, they were pleased with the amazing growth they made that year.
From then on, the colony continued to grow in membership and strength until it reached a total of 42 active members in the spring of 2007. After petitioning to the national office of Tau Kappa Epsilon, the current Grand Epiprytanis (National Vice President) traveled to Saint Leo University on April 27, 2007 to formally install the Sigma-Theta Colony into the Sigma-Theta Chapter once again. Since that date, the chapter has continued to develop as the best fraternity in the world - Tau Kappa Epsilon.
