Hi there! My name is Rylee Stephenson (she/her) and I am currently pursuing my MPH in Global Environmental Health here at Rollins. I received a B.S. in International Health and Spanish with an emphasis in community development from Clemson University in South Carolina. After graduation, my deployment to Peace Corps Rwanda was delayed so I returned home to Cincinnati, OH to work for the local non-profit Healthy Moms and Babes. I made the difficult decision to defer my Peace Corps deployment and come back to graduate school, which turned out to be the best decision! When I’m not studying, I enjoy spending time with friends, going for walks and exploring all that Atlanta has to offer.
