Her career as a planner started just after 9/11 when she was tasked by the Service Employees International Union (SEIU) to organize a memorial service at St. Patrick’s Cathedral in New York for members killed in the 9/11 attacks.

With a strong desire to work internationally, Sarah found her way to the Pharmaceutical Research and Manufacturers Association (PhRMA), where she focused on meetings and events in Asia and Latin America.
