About Ace of Clubs Trampolining

aoc logo 2.jpg

The aim of Ace of Clubs is to make classes enjoyable, fun, and educational, enabling the performer to get the most out of their sessions with us, and to most of their talents and abilities. We strive to make our students believe in themselves and gain confidence and skill which will benefit them in all aspects of life and not just the sport. We have gained our ClubMark and GymMark quality assurance status, meaning that your child will be in the safest of hands and be taught to the highest standard. We work with schools assisting their GCSE students as well as those working towards their Duke of Edinburgh Awards. We have worked with Team GB Aerial skiers, Olympic divers, those working towards the stunt register to name but a few .
