Just after her 15th birthday, Brown joined Premier League National Division team Liverpool Ladies. She was scouted at an Easter holidays goalkeeping camp run by Bob Wilson in London, where Brown was the only female of 48 attendees. After applying for the camp through "Match" magazine, Brown was presented with the Player of the Camp award by David Seaman. Having expected to understudy Liverpool's experienced former England goalkeeper Tracey Davidson, Brown became first choice when Davidson quit football approximately three weeks later.
