At UnitedHealth Group, our mission is to help people live healthier lives and make the health system work better for everyone.

We believe everyone–of every race, gender, sexuality, age, location and income–deserves the opportunity to live their healthiest life.

Today, however, there are still far too many barriers to good health which are disproportionately experienced by people of color, historically marginalized groups and those with lower incomes.

We are committed to mitigating our impact on the environment and enabling and delivering equitable care that addresses health disparities and improves health outcomes — an enterprise priority reflected in our mission.
