Originally from Westchester, New York, Sarah moved down south to pursue her undergraduate degree at The University of Maryland, where she received a B.A in Communications with a minor in Leadership Studies.

When Sarah first joined Proof Strategies, she had experience in the nonprofit communications industry and was a perfect fit to help service our nonprofit and foundation clients including The Mastercard Foundation, Active Minds and more. Sarah started out as a Fellow working across many accounts to advance both her earned media and digital skill sets and has since moved up from Fellow to Associate Account Executive and now her current role as Account Executive.
