After making aliyah (moving to Israel) from the US in 2000, Gitler began his food rescue efforts from his car by rescuing meals from catering halls and delivering them to local nonprofits that serve the needy. Eventually, Gitler founded Leket in 2003, working with 200 partners to collect and redistribute more than 28 million pounds of fresh, perishable, quality food that would otherwise be considered waste from farms, hotels, military bases and catering halls.
