McKenna earned her B.S. in Human Biology, Health, and Society from Cornell University in 2020, where her studies took her to India, South Africa, and Brazil to explore reproductive health challenges in diverse communities. These experiences solidified her passion for improving healthcare in low-resource settings, leading her to a post-graduate role as a program coordinator with CureCervicalCancer (CCC), a nonprofit dedicated to cervical cancer elimination. There, she spent four years working with her team to expand access to cervical cancer screening and treatment in low and middle-income countries, including designing and implementing a fully mobile HPV testing and treatment clinic in rural Kenya. Now a class of 2028 M.D. candidate at the University of Colorado School of Medicine, McKenna continues her HPV-related advocacy work as Vice Chair of the Global Initiative Against HPV & Cervical Cancer (GIAHC) Young Leaders program. She is passionate about mobilizing young leaders to drive change in HPV prevention and cervical cancer elimination.
