Beta Sigma Psi continued to prosper in the 1960s due to its growing membership, its common faith principles, and the strong leadership of alumni such as John Hingst of Beta chapter and Larry Edwards of Zeta chapter. Throughout the decade, new chapters were formed at several new campuses, including Western Michigan University, Eastern Illinois University, and the University of Minnesota. Growth was so rapid that the fraternity decided to add a full-time staff person. Although Del Lienemann had served faithfully as a loyal volunteer in the role of Secretary-Treasurer, the National Council decided in 1965 that in order for Beta Sigma Psi to become a strong national fraternity, it needed to have a full-time employee. Dick Weiss, an alumnus of Epsilon chapter, was named the fraternity's first salaried Secretary-Treasurer, and the National Headquarters office was moved from Omaha, Nebraska, to St. Louis, Missouri.
