Dr. Harsh was originally drawn to GAC because of its people and mission, and those reasons keep him here today. "I get to do meaningful and interesting work each day, and I have an opportunity to invest in the lives of our students and to create value for our families. GAC does this by providing an engaging and nurturing environment for students to explore broad interests, develop their passions, advance in their intellect and skills, practice leadership, and cultivate their faith."
