Katelyn has received international acclaim for her advocacy work regarding sexuality education. In April 2013, she rose to prominence within the social justice community after retaliating against her high school principal, who solicited private religious donations to bring speaker Pam Stenzel to her public school. She has since appeared on BBC, CNN, ABC's 20/20, the Young Turks, and in the New York Times, Jezebel, 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.
