Oliver Wyman For Society: CommunityOliver Wyman employees serve and strengthen local communities by volunteering and fundraising, mentoring to nonprofit organizations, and through sustainability efforts. Improving a neighborhood community center, raising money for disaster relief research, or cleaning up graffiti laden walls are just some of the ways employees get involved. We also have a “Green Champions” program that focuses efforts on energy reduction campaigns, recycling programs, eco-themed volunteer events, and the promotion of Marsh & McLennan’s award-winning Green Traveler Program.
