Yuanna Benjamin

Hi, my name is Yuanna Benjamin and I am going into my third and final year as a Biomedical Sciences Major. I am on the pre-dental track and am passionate about equitable healthcare access. During my study abroad with the Honors College to the Dominican Republic, I got to serve in underserved Haitian and Dominican communities where I met the nicest people and learned so much, which ignited my passion in promoting equitable healthcare access to all. 
I love to spend time with family and friends, go to the beach and try new foods. I also serve as a Sunday school servant at my church. I am super excited to participate as secretary of Medi-Futures USF and look forward to an awesome semester!
