Mark grew up in New York City but went to college in Bethany, WV - a campus and town with a total of 500 people. After earning a B. S. in physics, he relocated to the Washington DC suburbs where remained until his recent retirement. He spent his first decade professionally developing sophisticated computer models optimizing the allocation of U. S. nuclear weapons to targets. Realizing the evil nature of this work, for the next decade he served as an energy-environmental consultant to the Department of Energy and the Carter White House. He also completed his graduate work in public law and served 2 terms as president of Common Cause Maryland. The third and final phase of his career was spent running his own organization development firm, The Dorlester Consultancy, exclusively helping non-profit national associations serving challenged children and adults.
