Gateway Community Development Corporation
Gateway CDC is a nonprofit membership planning and development organization formed in 1998 by the residents of North Brentwood, Brentwood, and Mount Rainier - three diverse municipalities bordering northeast Washington, D.C., in Prince George's County, Maryland. Recognizing that they are more effective in directing change with combined resources and a shared vision, these municipalities devised a joint revitalization strategy that promotes their strongest asset - the high number of artists and art organizations in the community. To launch their vision, the Gateway Arts Summit was convened in 1998, bringing together a coalition of artists, residents, business owners, government agencies, and elected officials and laying the groundwork for the development of the Gateway Arts District.
