Meet the
Keepers of the Flame

It takes a lot of dedicated folks—running on bottomless reserves of energy—to produce over 50 innovation camps. Our crew is talented and diverse, encompassing educators, economists, scientists, artists, refugees from the corporate world, and at least one surf instructor.

Practicing what we preach, Galileo is a highly collaborative operation. Here you can meet some of our leaders and key players. We’ve grouped them into two categories: those who manage the teams at our headquarters—handling curriculum development, forging strategic partnerships, delivering signature customer service—and those who oversee the total camp experience, from building relationships in our communities and schools to hiring and mentoring camp directors and staff.
