Beta Omicron was installed at St. Lawrence University as the fifth NPC sorority on campus. The chapter began as local Phi Omega Phi, which was organized in 1934, and was outstanding in scholarship and leadership. In the 1930s and '40s, Beta Omicrons achieved many "firsts" including Grace Nilsson as the first female editor of the then 50-year-old campus magazine; Betty Greenleaf as the first female managing editor of the college newspaper; Betty Leonard as the first woman president of the student governing society and Frances L. Cotter as the first woman secretary of the university. A new chapter house was built in 1938 and the group was consistently highest in scholarship. Alice B. Caldwell served as housemother for 22 years and was initiated upon her retirement in 1971. The chapter closed in 1983 due to lack of faculty and campus support of the Greek system.
