For just over a decade, Middleton High School Social Studies teacher Andy Hartman has led students on study tours across Europe, Asia and the Caribbean. These trips have given hundreds of MHS students the chance to learn social studies and world history not just in classrooms, but through real life experience. But since the first tour in 2009, the opportunity has been exclusive — with steep price tags, limited scholarship options and destinations restricted by travel safety guidelines. Hartman is on a mission to change that.
