Sarah Schlemeier Henke attended the University of Missouri from 2010-2014, where she graduated Cum Laude with her Bachelor of Health Sciences and minors in Psychology and Service Learning. After working in the nonprofit sector in grant-funded positions, Sarah was hired by a lobbying firm before transitioning to the Gamble & Schlemeier team. Seeing a need in advocacy, Sarah started her own company, Advocacy360. Advocacy360 helps with the development and building of coalitions and grassroots networks. She splits her time between the two companies, as Advocacy360 is housed in the same office as Gamble & Schlemeier. Advocacy360's clients include some of the largest trade associations in Missouri. Recently, Sarah completed a graduate program through the University of Missouri, obtaining her master's in Public Affairs from the Truman School of Public Affairs. She currently resides in Columbia, MO, with her husband, Hayden; her sons, Wallace and Graham; and their dogs, Teddy and Ziggy.
