Since joining Major League Soccer, Beckham has been a very public advocate in the United States for related charities such as "MLS W.O.R.K.S." On 17 August 2007, he conducted a youth clinic in Harlem, along with other current and former MLS players. This was in advance of his first New York City area match the following day against the New York Red Bulls. That team's Jozy Altidore and Juan Pablo Ángel were also with Beckham, teaching skills to disadvantaged youth to benefit FC Harlem Lions.
