Who We Are

Relentlessly focused on the constant quest for better performance. 

As a team, we are collectively dedicated to the notion that optimal human performance is the most powerful driver of positive outcomes. And at the risk of sounding grandiose, we truly believe that better leaders beget not only better organizations but a better world.

Our team is composed of curious, energetic, humane individuals with diverse backgrounds who are always seeking to bring out the best in ourselves and each other. So we go to work every day helping senior leaders across all sectors to push their limits and find pockets of opportunity.

For us, being the best — being your best — isn’t a destination, and it doesn’t mean there’s no room for improvement. On the contrary, like elite performers in everything from business and technology to academia and sports, we believe that an integral aspect of being the best  is the understanding that there are always opportunities to elevate your game.


At Pennington, we believe that the effects of our work should ripple outward, but mostly forward.

Our Origin Story

How it started

Pennington Human Dynamics began as a lumber company — before the invention of color photography.

Not really, but it sure seems as though we were a bunch younger then, compared to now. It was 2002 when we joined forces and began our quest to help organizations get the most out of their leaders, teams, and unique cultures.

Our global team of coaches, consultants, and subject matter experts enables us to adapt quickly to client needs and deliver solutions efficiently, at the right scope, scale, and speed.

Our Impact

“Having experienced many leadership programs in my career, Pennington Human Dynamics is truly an innovative intersection of leadership development and executive mindfulness. The backdrop to this experience is a supportive environment that provides perspective that simply cannot be gained in a traditional learning context. The program was an experience I will never forget, providing me unattainable clarity in a moment when I needed it most in my career and life.”   

"When teams partner with Pennington and get into the team performance work, it’s an epiphany, because 99 out of 100 teams haven’t seen this. Getting that epiphany, that buy-in, is part of the secret sauce of Pennington because not everyone can do it."

"They bring authenticity, plain language, and a deeper insight. They see the world with uncommonly perceptive eyes. Pennington has the guts to take the conversation forward to where it needs to get. They’re a force multiplier for teams because of their ability to be there and be deeply relatable and deeply expert at once."

"What makes Pennington unique to me is they connect with you on a very real level, very human level. It’s not theoretical, academic, lecturing. It’s just real. In their very direct and understanding way, they get to the core of the issue quickly and dispense information that’s highly usable. Their insight is remarkable."
