Kirstin is a former English and social studies teacher, education entrepreneur, and art historian. Her work emphasizes elevating student success by building teacher and administrator capacity and skills through professional development. Before joining the HMH team, she taught full inclusion and IB world history, U.S. history, and ELA in several Pittsburgh, PA middle and high schools.
