She is a graduate of Michigan State University (Go Green!) and studied International Development from the Department of Community Sustainability there (Masters of Science).

Training Designer
Sean first became aware of agroforestry’s potential to transform rural livelihoods while serving as an Agricultural Extension Peace Corps Volunteer in Cameroon. After extending his service for an additional year to help manage an agroforestry demonstration farm, Sean joined Trees to assist in revising and improving our training framework. Since that time, Sean has worked to produce new components and innovations to the Forest Garden Training Program in order to improve the food sovereignty and economic mobility of smallholder farmers. He holds a B.A. in anthropology from Ohio University and is currently a Master’s candidate at American University where he studies rural development, agroecology, and sustainable food systems. Outside of the classroom and the office, Sean can usually be found wandering about DC’s many museums and galleries, playing video and board games with friends, hunting, fishing, and hiking outdoors, and futilely cheering on the Cleveland Browns on game days.

Most recently, Arianna moved from the Chicagoland area to join the TREES team and is eager to begin exploring her new stomping grounds. When not geeking out over all of the possibilities that new media offers to do good in our world, you can find her spending countless hours at used book and thrift stores, devouring book after book, drinking coffee while listening to folk music, going for extremely long walks, doing some kind of art or scouting out as many free events to go to as possible.
