Paragon gym, deceptive in the sense that it's not only a gym but so much more. I was at this gym for just under a year on/off, leaving due to personal reasons. The teaching is second to none, the community and atmosphere ensure your learning is effortless. The coaches are diverse and orientated in such a way that they'll identify any issues you have before you do.
For kickboxing, Stuart Lawson's not only a master but an inspiring instructor who gives himself to his students without question, a sensei who is honest, loyal and truely gifted.
Also, John Lawson (founder), Hazel Gale, Lisa Kent, Mark Walker, Lorraine Strudwick and Rob Waran are equally equipped to give you the best tuition and bring the best out of you, whether it be in a class or on a one to one basis.
For boxing, Keith Morris can take you from novice to anywhere your capability dictates. He's generous with his time and knowledge as well as his superb technical skills. If you've done any boxing before, this is the coach you wish you'd had, he encapsulates the sweet science.
If you spend enough time at the gym, the people will look after you, you won't realise this place is a gem until you leave.
