Dunn-Edwards, National City

Most people have seen the work of Dunn-Edwards, even if they don't realize it. That's because Dunn-Edwards has been covering the Southwestern United States in vibrant interior and exterior paints since 1925. The company's long-lasting colors have been used in architectural projects from Albuquerque International Sunport, to the Los Angeles County Museum of Art, to your neighbor's new rumpus room.

Despite that storied history, the Dunn-Edwards team is keeping an eye on the future. In 2011, they opened a new 336,000-square-foot manufacturing facility that's LEED Gold certified, specifically designed to be the most eco-friendly paint-making plant around.
