I’m honored to be the Press Director for BRAMUN 2025. I’m thrilled to be able to contribute to the conference's mission of fostering global understanding and diplomacy through the art of journalism. My goal is to show all of the tears and laughs that come along with a model UN conference, as it truly is a one-of-a-kind experience for me and for everyone who has been a part of it. Nevertheless, let's seize this opportunity not only as an incredible learning experience but also to create lasting memories and friendships!
