What Our People Are Saying

“The vision and values of our company are exemplary. We have a culture that offers mutual support, promotes trust, rewards efforts, and endeavors to ensure colleagues know their contribution is meaningful. My role excites me because I feel challenged, and this enables me to continually grow and learn new skills, and I feel respected and valued for what I bring to the business. Marsh McLennan is a company where clients receive exceptional service and colleagues are given the opportunity to excel and advance. I love being a part of an organization that strives to make a difference in our industry.”
Yvonne Ehinmoti
Client Advisory Leader, Marsh UK
“My favorite part about working at Marsh McLennan is the people. We're a hodgepodge of different backgrounds, personalities, and interaction styles and we blend so well. I've never worked with a group of people that genuinely get along as well as our team does, from my peers to our leadership. Before I'd received my formal offer after interviewing, our practice leader reached out directly to ask me to join. That remains one of the single most impactful things that has happened in my career. I'm also very involved in our Racial & Ethnic Diversity (R&ED) and Women at Mercer groups. As a former Marine, I am interested in the intersectionality of veterans and other historically marginalized and underrepresented groups.”

“I’m part of the leadership for Gays, Lesbians, Bisexuals, Trans* & Allies (GLOW) Colleague Resource Group at Oliver Wyman and am continuously helping to create new I&D campaigns for our LGBTQ+ colleagues. This year we launched our mentoring program with close to 50 participants around the world. Mentees are learning about how they can thrive in the workplace and use their diversity to their advantage. Having someone to aspire to be like is extremely powerful for some of these mentees as well; I’ve experienced this firsthand. I’m grateful to be able to spread empathy and collaboration across our firm in everything I do.”
Mark Jeyaraj
Senior Consultant, Oliver Wyman Australia
“I approach each day with constant passion and devotion to my career. Five years ago, I came in as an intern with pure hope and aspiration to ultimately walk away with industry knowledge and expertise. What I have found, is far beyond that. I am grateful to have amazing leadership and mentors that represent my Hispanic/Latin culture and prove that we have a voice in all fields, all departments, and all roles. Marsh McLennan has supported my personal development in not only succeeding in my position, but also aligning my skillset to a career path that can move horizontally and vertically within our company.”
