Mark earned his BA from Williams College and his M.Ed. from the University of Pennsylvania. Mark began teaching at a Quaker school in Philadelphia after graduating from Williams College, with the idea that he would teach for a year and then move on to a “real” career. That was 30 years ago. Mark is blessed with a talent for motivating middle school students and respecting them as thinkers and writers. He returned to his roots on the East End in 2000.
