Approximately twenty percent of the Heidelberg campus belongs to a fraternity or a society. These Greek organizations have played an important role in Heidelberg's educational and social life. Recruitment of new members occurs each year.
There are eight Greek letter organizations that make the Greek community at the Berg. Alpha Phi Tau ΑΦΤ, Excelsior Men's Society ΕΧ, Nu Sigma Alpha ΝΣΑ and Sigma Tau Nu ΣΤΝ are the fraternities and Delta Sigma Chi ΔΣΧ, Euglossian Society ΕΥΓ, Kappa Psi Omega ΚψΩ and Philalethean Society Φ are the societies.

Each organization strives to promote its unique qualities and characteristics. Established originally as purely literary societies, these societies and fraternities have developed into organizations committed to providing opportunities for character-building, leadership development, campus involvement and scholarship.
