Born in Yaoundѐ, Cameroon, Patrick Ada first made his mark on the English game with Redbridge during the 2004-05 season. He signed for Barnet in March 2005 but after a couple of Reserve team appearances had a short spell with Stevenage Borough.
He joined St Albans City, under Colin Lippiatt, for the start of the 2005-06 season and appeared in 37 (ten as a substitute) of our 43 Conference South matches as promotion was secured to the Conference National via a play-off final win over Histon at Stevenage. He left at the end of the season for a full time career with Conference National side Exeter City. Patrick made nine appearances for the Grecians before being loaned back to the Saints in January 2007. At the conclusion of his loan, in March, City were already almost certain of being relegated just twelve months after gaining promotion.
He scored one goal for St Albans, that came during a 2-0 win over promotion rivals Lewes at The Dripping Pan in February 2005. Earlier that season he was one of three City players dismissed during a 4-0 F.A. Cup 3rd Round Qualifying defeat away to Kettering Town.
He signed for Histon in the summer of 2007 and was ever present in the Cambridgeshire club’s first season in the Conference National. In May 2009 he moved north to sign for Crewe Alexandra and spent two years at Gresty Road. Kilmarnock offered him a two-year contract at the start of the 2011-12 season but he was released in the February of that season. After a short spell, three games, with Burton Albion, he joined Ebbsfleet United. He made 19 appearances for the Stonebridge Road outfit but his career ended in December 2012 when he was convicted and sentenced to five years for a rape carried out the previous March.
