As a senior, Lochhead led UCSB to the finals of the 2004 NCAA Division I Men's Soccer Championship where the team fell in penalty kicks.

Before attending UC Santa Barbara, Lochhead played with Tauranga City United AFC of the New Zealand National Soccer League.

While enrolled in college, he appeared in 10 games for USL Premier Development League team Orange County Blue Star and scored one goal.

On 13 April 2007, the Revolution waived Lochhead to free up a senior roster spot for former UC Santa Barbara teammate Bryan Byrne who was signed the same day.

In January 2014 it was announced that newly appointed head coach, Wilmer Cabrera, had signed Lochhead to Major League Soccer side Chivas USA.

Lochhead continues to play for the New Zealand national team and helped the Kiwis qualify for the 2010 World Cup Finals in South Africa.
