Marc Miller

Marc Miller has a Ph.D. in clinical psychology from Adelphi University (1978) and also received a Postdoctoral Diploma in Psychotherapy and Psychoanalysis from Adelphi (1983).

After many years practicing psychotherapy, Marc shifted to the related field of professional/executive coaching by earning a Professional Coaching Certificate from the Professional Coaching Program at the Zicklin School of Business, Baruch College, CUNY and iCoachNewYork (now iCoachGlobal), where he currently serves as a faculty member and coaching supervisor. He has earmed the prestigious credential of Professional Certified Coach (PCC) awarded by the International Coaching Federation (ICF).

In addition to his training in individual coaching, Marc has completed the Foundations in Team Coaching Certification from the Global Team Coaching Institute (GTCI) and then acquired GTCI’s Practitioner Certification in Team Coaching (2022).

Marc’s professional practice focuses primarily on executive-organizational coaching, working with individual business leaders, managers, and professionals, and with organizational teams. His expertise is in understanding how each individual’s unique personality, including their strengths and sensitivities, influence their behavior and communication effectiveness in the workplace, in business, and in relationships. His coaching style provides a psychologically safe space for leaders and teams to gain greater self-awareness, which leads to their greater ability to avoid interpersonal misunderstandings and to promote greater alignment with others, to foster personal, professional, and organizational/team success.
