On working at FSG

“The complexity and magnitude of the social challenges we face today require collective solutions, involving all key stakeholders. That is what has always driven my work, from my Davos years to the present day at FSG. I have been fortunate to collaborate with leaders in all sectors on an incredible variety of initiatives to advance social change. As the son of two refugees, with my own family spread across three continents, I find FSG’s work in the global arena both professionally and personally meaningful.”
