As a company, we are defined by mutuality and our vision to put customers first. It's more than our company structure - it's our way of life. We are a company of people protecting people. Our company exists because people are willing to share risk and resources, and rely on each other when it counts. At MassMutual, we Live Mutual.  

We're focused on fostering new technology ideas and developing longer term business solutions.  As we expand our operations in Boston we are committed to strengthening our community involvement through business, civic, cultural and corporate responsibility initiatives.
