Adjunct Instructor in Education

Stephen “Steff” Chortanoff earned degrees at Lycoming College (B.A., History), Pennsylvania State University (M.A., American Studies), Temple University (M.Ed., Educational Administration), and the American Military University (M.A., History).  Over the last dozen years, he served as an AP European History teacher, Dean of Students,  gifted support teacher, and creator and instructor of dual enrollment college history courses (Second World War, American Civil War and Reconstruction, 20th Century America, and the Vietnam War) at Lower Dauphin High School. In addition, he serves as an adjunct faculty member at Gratz College (education) and Ashford University (education, history, military history, and political science).  He created and leads an oral history project, associated with the US Army Heritage and Education Center and Library of Congress, to connect students with 'makers of history,' such as veterans, service members, activists, politicians, and Holocaust survivors.

Whether teaching in person or online, Steff strives to inspire all students with a love of education.  A driving force of Steff’s vision for education comes from Dr. Martin Luther King, Jr., who in 1947 said: “To save man from the morass of propaganda, in my opinion, is one of the chief aims of education. Education must enable one to sift and weigh evidence, to discern the true from the false, the real from the unreal, and the facts from the fiction. The function of education, therefore, is to teach one to think intensively and to think critically.”

Steff resides in Pennsylvania with his wife, Courtney, and two young children.
