Leslie Mosteller moved to the DC area from Charleston, SC, in 2014. She holds a Bachelor of Arts in English from Davidson College in North Carolina. Upon graduating from Davidson, she studied global health and communication as a Rotary Ambassadorial Scholar in Australia, earning a Master of Arts in Health Communication from the University of Sydney in 2011.

Leslie worked on several community development and health informatics projects in Charleston before moving to DC for PA school, earning her Master of Science in Physician Assistant Studies from George Washington University in 2016. She loves working with pediatric patients and worked in the Emergency Department at Children’s National for two years prior to joining PAA in 2018. She is board certified through the NCCPA and holds licensure in DC and Virginia.

Leslie has special interest in global and community health and has served on community health projects in the Dominican Republic, Peru, Australasia, and, most recently, in Uganda.
