Katelyn has received international recognition for her work in advocating for comprehensive, evidence-based sexuality education. In April 2013, a lawsuit she filed against her high school principal, who solicited private religious donations to bring abstinence-only sex ed speaker Pam Stenzel to her public school, made national news. Katelyn has since appeared on BBC, CNN, ABC's 20/20, the Young Turks, and in the New York Times, Jezebel, the Nation, OZY, and Seventeen Magazine. 

Katelyn has delivered remarks at NARAL Pro-Choice Missouri, the Secular Student Alliance National Conference, and Partners in Sex Education's annual conference.
