Nancy Popp

Developmental Psychologist and Coach

Kegan's developmental perspective has always been an integral part of my coaching-as a powerful support for my clients in navigating the challenges of their life and work. It provides a road map, if you will, to help them understand where they are, where they want to be, and, most importantly, how to get there. Like embarking on any journey, we cannot figure out our route without knowing where we are starting from. Paradoxically, being grounded in where we are actually gives us the stability, confidence, resilience, and vision to move forward. For me, this work has always been about understanding the importance of being understood. It is about being fully grounded exactly where we are. After 35 years of using this developmental perspective, it is still my gold standard.
