This past year UCSF’s Program in Medical Education for the Urban Underserved (PRIME-US) had the pleasure of working with EXLI. Our collaboration focused on introducing the concept of Emotional Intelligence to our learners and identifying ways they can incorporate that into their professional development. They are a very creative and energetic team. They worked with us to develop a robust training for the students, faculty and staff which proved to be thought provoking and valuable for us all!
