Sigma Tau Nu fraternity was Heidelberg’s first social fraternity. The Sigs have sought to build a group of men with backbone and strong initiative who will uphold and strengthen the traditions and standards of the university. This goal is apparent through the many different leadership roles the Sigs have assumed in Student Senate, Greek Council, The Kilikilik, Berg Events Council, athletic teams, and countless more organizations. Within our group, bonds are created that can never be broken. Each member believes in the strong vows he has taken and the real brotherhood that has developed throughout his time at Heidelberg. A new member knows he has become a Sig as a result of the personal growth he has developed within the fraternity—acquiring the skills to be brave, self-reliant and ever striving to better himself.The Sigs take pride in giving back to the community; we work with individuals from the Elmwood Assisted Living Center, the Seneca House, and the Humane Society. Also, every fall we perform a Rock-A-Thon at local businesses in the Tiffin community in order to raise money for the American Cancer Society, and in the spring we host a dodgeball tournament for the Alzheimer’s Association. The Sigs can only exist when they are the best in everything they do, with a willingness and determination to always guide the way for all.Our motto is Nulli Secundus, which means “second to none,” a belief that every Sig lives by. Go Greek!
