William Meckley
Marketing Manager

William Meckley graduated cum laude from Fordham College at Lincoln Center in 2016 with a BA in International Studies and Communications. As an undergraduate, William spent a year supporting the work of Justice Rapid Response, LLC. JRR is a non-profit entity which partners with national governments to deploy legal, cultural, and forensic experts to investigate gross human rights violations. As an intern there, he spearheaded a variety of high-profile research and administrative projects.

Through Fordham’s Global Outreach program, William traveled to Nicaragua and Colorado on service projects centered on social justice issues. Through this organization, he was humbled by the opportunity to lead a team of volunteers to support low-income housing renovation in western Pennsylvania in his final year at Fordham. It is these experiences which initially inspired him to pursue work benefitting non-profits. He is eager to continue supporting a broad range of non-profit organizations and their causes at Crowdster.
