Drawn not only to girls’ education but specifically to Hewitt’s commitment of valuing the individual girl, Amy was thrilled to join the Hewitt admissions team in the fall of 2012. She began at Hewitt as the assistant director of lower school admissions, focusing primarily on kindergarten admissions. She later took over the middle and upper school admissions program and was appointed director of admissions in 2014. Amy feels privileged to work with such a dynamic, passionate, and compassionate admissions team.

Prior to Hewitt, Amy served in the Admissions Office at Blair Academy, her alma mater, where she traveled extensively recruiting a diverse student body, coached field hockey and lacrosse, served as an advisor, and was an assistant house master in a junior and senior girls dormitory.

Amy is a graduate of Barnard College, class of 2003, where she majored in English with a concentration in American literature and where she played lacrosse for the Columbia University Lions. Amy has a deep love of the mountains and is an avid skier in her free time.


Melissa Cassis, Senior Associate Director of Admissions

A member of the class of 2008 at Middlebury College, Melissa received her B.A. in International Studies with a focus in European literature and culture. She began her career in education at the Dexter Southfield Schools in Brookline, MA, where she discovered the wonderful benefits of a girls’ education in her role as assistant director of admissions and coach of Southfield’s JV soccer and middle school basketball teams.

Melissa’s passion for independent school admissions and desire to explore the classroom led her to Greenwich Academy in Greenwich, CT where she assumed exciting new responsibilities as a teacher and advisor. Throughout her seven-year tenure at GA, she worked as associate director of admission, taught middle school computer science and digital art classes, coached JV basketball, and advised eighth grade girls.

Melissa is beyond thrilled to join the vibrant and savvy Admissions team at Hewitt, a distinguished school committed to empowering young scholars to lead meaningful lives. She looks forward to advising a group of seventh grade girls and becoming immersed all aspects of life at Hewitt.
