After her discharge, Williamson returned to Kansas City and acquired a job as the public relations director for the Kansas City Tuberculosis Society. Through this position, she was offered an opportunity to further her education, and eventually went on to obtain her master's degree from Columbia University in New York. After graduating, Williamson moved to Washington D.C., and took a job as an editor. However, wanting to be closer to her home, Williamson returned to St. Louis and accepted a position in broadcasting. Williamson began teaching in the Department of Speech and Mass communication at the University of Nebraska Omaha in 1969. Her first year at UNO Williamson taught courses such as Speech 101, Introduction to Mass Communications, Television Production and Radio Production. Williamson also served as PanHellenic advisor to the Greek communities on campus. Williamson finished her doctoral program in 1973 with the publication of her thesis "An Inquiry into Excellence in Commercial Broadcasting". Williamson incorporated work experience with the Nebraska Business Development Center in many of her courses, so that students were able to provide services and advice to small business owners in the Omaha area.
Throughout her time at UNO, Williamson served in various roles across campus. She was elected to Faculty Senate and served her second term as Vice President in 1977 and then as President in 1978. During this service, she successfully removed gendered language from UNO's diploma despite some strong opposition. Williamson served as the executive assistant to UNO Chancellor Del Weber from 1980 until 1986. Also in this time period, she was appointed Interim Dean for the College of Fine Arts for two years and later as the Interim University Relations Director, where she was responsible for public outreach for the university. After her interim stints in both departments, Williamson returned to the Communications Department as acting department chair. She took partial retirement shortly after and began working closely with NBDC as a business consultant. Williamson retired in 2004 after 35 years of teaching at UNO. In 1981, Williamson became an associate of the Women's Institute for Freedom of the Press. WIFP is an American nonprofit publishing organization. The organization works to increase communication between women and connect the public with forms of women-based media.
Community service
Williamson also worked as the Vice President of Nebraska Cable Television and was later appointed by the mayor of Omaha to the community's Cable Television Advisory Committee for two terms.
After retirement she remained active around Omaha by filling a volunteer capacity in various organizations. Williamson served as an ombudsman at the Ambassador Rehabilitation Center, a counselor at the Service Corps of Retired Executives, and assisted the Hearts United for Animals shelter.
