The renovated Marine Mammal Center in the Marin Headlands of Sausalito averages more than 100,000 visitors annually, including tourists and local students. The renovations, performed by architectural design firm HGA Architects and Engineers, mark the first renovations of the visitor center since its grand opening in 2009 when the number of annual visitors averaged less than 30,000. The center's new touch-screen exhibit will allow visitors to look behind-the scenes through photos, s and live-stream feeds of various places throughout the hospital.
