Encouraging creativity in our youth

We believe critical thinking is essential to solving our world’s most pressing problems, and there’s no better way to develop those skills than through an arts education. Marsh & McLennan Companies CEO Dan Glaser was acknowledged for that conviction by Young Audiences New York.

In today’s increasingly complex and uncertain world, one of the few certainties is the currency of critical thinking, a byproduct of an arts education that encourages restless imagination and refined reasoning skills.  This philosophy of our CEO is shared by Young Audiences New York, which honored Glaser and two other leaders for their commitment to arts education at the 2015 Children’s Arts Awards.  Young Audiences New York  is dedicated to providing children from all walks of life with an arts education to nurture their creativity and help develop important life skills. This year’s benefit raised nearly $1.2M, the largest amount in the organizations’s history.

The Pursuit of a Smarter Way

Clients bring us their most challenging problems. One of our most vital roles is to imagine what the future could be — and make it present.

We challenge ourselves every day to change what is possible.

THe Sustainability Imperative

Much of our work involves helping our clients analyze, reduce, and reverse the environmental impacts of business activities. And we try to lead the way ourselves.

We help turn sustainability from a distant goal into everyday practice.
Here’s what some of our colleagues are doing right now.


Oliver Wyman consultants advise our clients on how environmental factors affect location, operational, and strategic decisions; while our “people” experts at Mercer transform client organizations to make sustainable practices part of the culture. Specialists at Guy Carpenter and Marsh help our clients quantify the impacts of climate risk and identify issues around the world.

Before we advise clients, we lead the way ourselves. Marsh & McLennan Companies has been named to the CDP S&P 500 Climate Disclosure Leadership Index for climate change transparency, scoring in the top 10% of the 2014 index.


At Marsh & McLennan Companies

  • Energy and materials conservation
  • Waste reduction
