The surviving chapters of Theta Kappa Psi followed diverse courses. "Beta Epsilon chapter" at Ohio State University continued as independent local fraternity until 1964 when poor finances caused it to fold. "Psi chapter" at University of Texas Southwestern Medical Center in Dallas pledged members up until 1968 as a local independent fraternity. "Gamma Tau chapter" at the University of Manitoba continued as an independent local fraternity until it became inactive in 1968. "Beta Eta chapter" at Jefferson Medical College in Philadelphia was an active chapter in Phi Beta Pi until 1966. At that time the chapter lost all formal structure when it allowed non-members to live in its fraternity house. In the 1960s "Beta Phi chapter" at the University of Texas Medical Branch, functioning as a local independent fraternity, emerged as the largest medical fraternity chapter in the nation with 130 members. The ritual, revised from the previous national initiation ceremony, was strictly followed. "Gamma Kappa chapter" at the Medical College of Georgia affiliated with Phi Beta Pi after the merger. This chapter was extremely successful in the 1960s building a new fraternity house in 1966. Although listed as a chapter of Phi Beta Pi, the group considered itself a member of Theta Kappa Psi.
