Sunnyvale, CA is located within the confines of Silicon Valley, attracting high tech employees and entrepreneurs from all around the world. Incorporated during WWII in 1912, it is the seventh most populous city within the greater bay area. Near both San Francisco and San Jose, Sunnyvale has the high real estate prices expected for its’ proximity to Silicon Valley.

High Tech is not the only draw for the city. Baylands Park offers hiking trails and a wetlands area, drawing people from all over the bay area. Located near the Great America theme park, there are also many friendly dog parks for canine lovers.

Once home to the famous Onikuza Air Forces station (named after Shuttle astronaut Ellison Onikuza) it was affectionately known as the Blue Cube because of its’ windowless architecture.

Sunnyvale today is one of the few U.S. cities to have a single Department of Public Safety where all police officers, fire fighters and EMTs are trained together so they can respond to any public emergency.

Being located in the heart of Silicon Valley assures Sunnyvale of a bright and prosperous future
