Our workforce reflects the people we serve

Diversity, equity, and inclusion impact all parts of our work. We stand committed to building a diverse workforce to better meet the needs of all our patients. That means working hard to reflect the communities we serve, across every dimension. We can all learn from each other’s cultures, perspectives, lifestyles, and backgrounds. In this way, we can create a better care experience for all.




The healers of tomorrow

Applied medical education has always been an important part of our identity. And there’s a reason why recent health care graduates from all over the world come to train at Mass General Brigham. Our Harvard Medical School physicians, researchers, and faculty are ready to help the next generation become their best.
