Andrea Pien

Ryan Coffey Keaton

Associate Director of College Counseling

Swarthmore College - BA
Stanford University - MA

Andrea believes that the anxiety around applying to college is in part rooted in our lack of a social safety net under late-stage capitalism. She believes that researching and applying to college can be a joyful and affirming experience, and she enjoys working with students and families throughout the process. Prior to working at Friends' Central, she worked as a college counselor in San Francisco and in China. She has also worked in the Swarthmore College admissions office and read applications for Stanford University, Wesleyan University, and the QuestBridge scholarship program. She loves trying new food in college towns. Outside of college counseling, Andrea is the Asian Students Association advisor at FCS. She is also on the Board of Directors at the Bread and Roses Community Fund, the leading funder of racial, social, and economic justice in the Philadelphia region.
