Working with Geoffrey is like training with Olympic athlete: you will get stronger. Whether it is in the audacity of the scale of your vision, the subtlety of your strategy, or the meticulous care of your execution, the quality of his leadership will improve your own performance beyond what you thought possible.

He’s strong in the day-to-day work that keeps an organization healthy, but Geoffrey is downright epic in a hard fight. The $50 million in funding he has raised is just one marker for his ability to find patterns in chaos, rally communities, and get work done.

As a team leader, he is honest, direct, and quick to share credit. He creates an atmosphere of shared goals and mutual support that makes for deep collaboration with very little drama—rare and delightful qualities in a work environment.
