About Us Banner


Nelson\Nygaard was founded in 1987 as  a partnership by two former San Francisco Municipal Railway managers, Bonnie Nelson and Diane Nygaard.  Together, they believed it was possible to create a transportation planning firm that fosters a fun, egalitarian and creative work environment, and that provides high quality, principled work for its clients. Starting in Diane’s basement, their company has grown to over 90 planners and engineers, with offices across the United States and a work base that covers five continents.
