Faculty & Staff

Sarah Ostermueller comes to us after five years at the Fay School in Southborough, MA, where she served as the Head of Upper School (grades 7-9), overseeing a program of 270 students, including 150 boarding students. 

Sarah holds a BA in Biology and Women’s Studies from Colby College, an MA in Teaching from the College of New Jersey as well as a certificate in Advanced Graduate Study in school leadership from the University of New England. Prior to her time at Fay, Sarah has held various faculty and leadership roles at the Greens Farms Academy in CT, Northfield Mount Hermon School in MA, the Hun School of Princeton in NJ, and St. Mary’s School in NC. Throughout her career, she has taught mathematics and science as well as coached softball, lacrosse, and field hockey. In 2001 she was named Field Hockey Coach of the Year after coaching the team in back-to-back state championship wins! 

Sarah writes, “I am excited to join the Sacramento Country Day School community as the next Head of Middle School. When I visited campus, I was impressed by the expertise and dedication of the faculty and the curiosity and openness of the students. It is clear that Country Day is dedicated to its mission to inspire and engage students and that it is committed to honoring and celebrating its diverse community. I can’t wait to move to California this summer and start leading the amazing Middle School in the fall.”
