Central Parking Systems, Baltimore

Though they keep an eye on more than one million parking spots around the country, the staff of Central Parking System is trained to do more than just oversee parking facilities; they also execute shuttle services, provide valet and special-event parking, and consult on parking-facility design. They manage parking and vehicular operations in 60 cities around the country in venues ranging from residential and office buildings to airports, hospitals, hotels, and stadiums.

In addition to maintaining streamlined parking environments, Central Parking System also devises creative solutions to modern planning dilemmas, such as whether or not to give discounts to clowns carpooling in a compact sedan. The company donates part of its profits to a range of local and national charities, such as The United Way and The American Diabetes Association.
