"I was helping a friend write a business letter when, after she grasped a concept in one of those ‘aha’ moments, gushed that I should teach at the college level. ‘You know what it takes in business, and the profs I’ve had don’t’, she said. Little did she know what she started: During the ensuing twenty years I’ve taught at the University of Pittsburgh, Carnegie Mellon University, and, now, at The Graduate School of Environmental Science and Management, Duquesne University. Here are a few of the comments from my students." —Pete Geissler

"The most beneficial course in my career... course content was broad and practical... the most helpful instructor in Duquesne’s ESM program... very helpful... very exhausting, but I learned a lot... great class! Best course I have taken at Duquesne."
