Storm Taekwondo boasted four gold medalists from the British National Championships.
More than 900 players from 82 clubs descended on the National Cycling Centre in Manchester.
And a teenage quartet from Edlington-based Storm were among those who came out on top.
Zak Lambert, 12, Jamie Leigh Smith, 11, Faye Bushell, 15, and 16-year-old James Tyler all won gold to become British champions in their respective age and weight class.
Nine-year-old Sam Fairhurst claimed a bronze with Charlotte Bateman, 15, also doing so.
Abbie and Terry Beedham also represented Storm and were unlucky to miss out on medals.
It was the first National Championships for Storm – based on Broom House Lane Industrial Estate – and they finished a creditable 17th of 82 teams.
Storm are currently recruiting new members.
