In a world increasingly connected yet divided by countless challenges, the imperative for robust professional networks has never been more critical. This session unveils the transformative potential of international dialogue and exchange through the lens of distinguished sector leaders. Drawing from their enriching experiences as Harkness Fellows in Health Care Policy and Practice across Europe and the United States, our speakers will delve into the myriad ways professional networks serve as the backbone for innovation and systemic improvement in healthcare. They will share insights on the dynamics of participating in a diverse cohort united by a shared mission to enhance health care, the impact of mentorship from luminaries in health policy, the significance of self-reflection in leadership, and the creation of a collaborative learning environment for knowledge exchange.
