Director of Programs & Administration

Prior to joining WorldDenver in 2017, Matt Britton served as a Foreign Service Officer with the U.S. Department of State. He also worked as a Health Education Volunteer with the US Peace Corps and as a volunteer with the Rio 2016 Olympics. His 12+ years of living abroad (United Kingdom, Mauritania, Papua New Guinea, El Salvador, Burundi, & Brazil) make him feel right at home with WorldDenver members and fellow "citizen diplomats" working to build bridges that span cultural, linguistic, and geographic divides in our increasingly globalized world. His diplomatic career included assignments in embassy administration and management, immigration services, communications and media relations, and management of international exchange programs. Matt holds a BFA in Graphic Design from the University of Tulsa and speaks French, Spanish, and Portuguese (as well as a smattering of Tok Pisin and Hassaniya, but you would be hard-pressed to find individuals who understand either of those languages!). Outside of the office, he enjoys spending time with his family, snowboarding, being out in nature, and collecting coins from around the world.
