The first "Grey's" spinoff to hit the air in 2007, "Private Practice" took neonatal surgeon Addison Montgomery out of Seattle. After her ex-husband Derek had found new love with Meredith Grey, Addison decides to leave Seattle and head down the coast to Los Angeles to restart her life. Reuniting with some old friends, Addison joins their medical practice and begins pursuing her own dreams, from new surgical pursuits to her hopes of having a family of her own. It ran for six seasons, ending in 2013.
