Superintendent Hall believes fervently in diversity and inclusive education. In January 2013, she received the Outstanding Administrator Award from the Missouri State Thespians Association. MRH teachers and students who performed in the High School’s play, The Laramie Project, nominated Hall. Former MRH High School student Cassidy Snyder wrote in the nomination: "Karen Hall has been an adamant supporter from the beginning. Her support was what made the show possible...when protesters from Westboro Baptist Church arrived; she was on the front steps, defending us through a megaphone.”
Hall is committed and passionate about ensuring educational excellence for all MRH students. She is dedicated to developing rich learning experiences in schools so that students develop leadership skills, are actively engaged in the community, have opportunities to explore social justice issues, and have access to artistic self-exploration balanced with academic rigor. In 2012, Karen directed her administrators to implement the Public Education Leadership Project, PELP, from Harvard University. The implementation of the PELP model’s systemic thinking is changing the achievement, alignment, and sustainability within the Maplewood Richmond Heights School District. The work is moving forward to close the achievement gap and ensure that all students achieve at higher levels.
Karen Hall’s passion for educational equity and excellence drives her relationships and leadership. She is committed to continuing the success of the district and building upon the strong foundation the community has created together.
