What experiences have you had that have prepared you to work with underserved populations? for example: community service, internships, and federally funded health programs; or work in rural, frontier or tribal settings?

You can start writing your experiences of how you gained masters in medicine and worked in health programs which protected undeserved communities.

Your write up can be of emotional appeal and avoid sentimentality or platitudes which sounds monotonous.

You can also write on how you simple and down to earth in order to serve the people who are different than you. The interaction with new people and what type of access you gained can also be expressed.
