Sector 9 was founded in 1993 in the backyard of co-founder Dennis Telfer's house. Living in La Jolla, California, Steve Lake, Dane Klimkiwicz, Dennis Telfer, and Tal O'Ferrell started building boards after their favorite deck was stolen. After a friend nicknamed the house Sector Nine, their unbranded decks became a business over beers, a pool table, and a hand shake. Based in San Diego, California, they produce skateboards, longboards, wheels, and apparel. Decks are produced with maple, bamboo, fiberglass, and/or carbon fiber. Sector Nine supports different board cultures and sponsors 10 downhill skaters, 7 skaters, 7 surfers, and 5 bands. Today, they are one of the largest producers of longboards in the world.
