Lynda Casarella, Interim Chief Financial Officer

Lynda Casarella
Interim Chief Financial Officer

Hailing from Maine, Lynda Casarella started at Poly Prep in 2015 as Associate Director of Summer Programs & External Learning. She began serving as Interim Chief Financial Officer in 2020. Lynda attended George Washington University and Salve Regina University, where she graduated with a BS in accounting. She earned her MBA in 2019 and is working toward her doctorate degree in business administration from William Howard Taft University. Lynda has always considered herself a “numbers person,” so working in accounting and finance is a natural fit. She also accrued business experience and financial acumen having owned and operated two successful small businesses when she lived in Rhode Island. When not balancing the ledgers and crunching numbers, Lynda enjoys keeping fit, sewing, and singing. A talented vocalist, you may have heard her sing at Poly events. One of her favorite quotes is, “The key to success is to focus on goals, not obstacles.”

Organized as a not-for-profit corporation under the laws of the State of New York and granted 501(c)3 status by the IRS, Poly Prep Country Day School is governed by a Board of Trustees, consisting of alumni and parent volunteers, who provide strategic oversight and ensure that Poly Prep fulfills its educational mission.  The Board meets approximately once every two months throughout the school year.  Through Board committees—ranging from Education and Co-Curriculars to Development and Finance—the Board has frequent and regular campus contact with parents, alumni, and school administrators.

Poly Prep also benefits from the active support of a Parents’ Association, and its Alumni Association and its Board of Governors.
