The Leading Good Podcast: Rod Arnold hosts Jonathan Halperin

When I began to unhook from SustainAbility in 2008, after 20+ years, to co-found Volans, Jonathan was working with the US end of SustainAbility — and sent the London end of the Volans team a large cardboard box of multi-colored felt rocks, which initially I couldn't make head nor tail of. I thought he was mad, or overly American.

But I have to say that, over time, those felt rocks have become a central feature of the Volans culture, thrown by team members at other team members (or guests) on the slightest provocation. That aside, he's a consummate professional, creative collaborator, skilled communicator, and keen intellect—and I am delighted both to have had Jonathan as a colleague and to now count him as a friend.
