In 2004, Dr. Gage authored a seminal work, still one of the few of its kind, detailing the comprehensive spectrum of interpersonal, commercial, and legal considerations that partners must address in their dialogues, negotiations, and contracts. This pivotal book is titled "The Partnership Charter: How To Start Out Right with Your New Business Partnership (Or Fix the One You’re In)." For more than ten years, Dr. Gage has served as an adjunct professor at American University's Kogod School of Business, where he imparts his wisdom in a course named “Managing Private and Family Businesses.” This course stands out as one of the rare offerings within U.S. business schools, dedicated to guiding both family and non-family partners towards nurturing prosperous and enduring partnerships.
