In Their Words

Voices From Our Family

"He's personally invested in the success of those he trains — for us he's family."

We have been working with Master Welch for a number of years. His passion for his craft is unambiguously clear! Our Northwood classes are something we never miss. I've seen that passion come across in all his training sessions. His versatility allows him to work with people of all ages and capabilities sometimes simultaneously! His personable approach makes sessions enjoyable and myself and the kids always look forward to our sessions with him.

For me I have seen continual tangible progress in my own journey, having eclipsed my personal best in lifting weights a number of times over the last year. I have seen the positive difference in my son too. His qualification and knowledge in mixed martial arts is also unparalleled. As well as technique, he frequently delves in to the technical detail so I can understand the what and the why and helps me really uplift myself holistically.

He's personally invested in the success of those he trains and that extends beyond the training sessions we have. For us he's family!

"Every child is recognised and part of the Diamond Kickboxing Family."

For over a year now, my two children, Jonah and Tamara, have been attending Diamond Kickboxing classes in Southall, and without hesitation, I cannot recommend them highly enough. From the very first session, Sam built a great rapport with all families, making them feel beyond welcome and supported. We can proudly say we are one of those lucky families. My children have grown so much — besides the fact that they have moved from belt to belt in their kickboxing gradings, but in their confidence, their discipline and their self-belief. Sam and his team have helped my children flourish in more ways than one.

The coaching across the entire team is incredibly well organised, engaging, and delivered by experienced coaches. The class teaches a perfect mix of self-defence, competitive fighting, and fitness. It is so clear that Sam puts so much thought and passion into every class he teaches, and this passion radiates into every child he teaches. All the instructors are experienced, approachable, and eager to help every child reach their full potential.

What I love most about Sam is his enthusiasm for encouraging the kids and his attention to detail when teaching all the children in his class. Every child is recognised and part of the Diamond Kickboxing Family. He knows exactly how to motivate them, celebrate them, and push them to do their absolute best!

As a mum, I have watched my children flourish not only in their kickboxing skills but also in qualities they can take into everyday life. They have learnt respect, resilience, determination, discipline, and focus. Jonah and Tamara leave each class with a big smile and come home to practice all their skills. I was thrilled when Sam started the adult classes, so I could join in on all the fun and, most importantly, learn how to defend myself from the kids!

The atmosphere is incredible, the training is second to none, and it is clear that the children are always the priority. Knowing my children are learning from Sam and his team tells me they are lucky to have such dedicated, professional, and caring coaches. Every time they step into a class, it is unquestionable that they are in the best hands.

All of us look forward to many more years of training at Diamond Kickboxing!

"My self-confidence has grown so much — I now feel calm and capable, rather than anxious or unsure."

My two boys and I have been attending these kickboxing classes in Northwood right from the very start, and we couldn't be happier — they are absolutely fantastic.

For my sons, aged 8 and 4, it has been such a positive experience. It has built their confidence no end, taught them to respect others, and given them skills to keep themselves safe. They get so excited for every class, and are so proud to be working towards their next belts. The training keeps them active and teaches them real discipline — lessons go far beyond kickboxing moves, covering important life skills too. The instructors are brilliant: they pay close attention to every child, adapt to their individual needs, and work closely with us as parents to make sure the boys feel seen, and their strengths are celebrated.

I joined the adult classes as well, and I've seen huge changes in myself too. At first I felt shy, and would hold back in my shell — but after over a year of training, my self-confidence has grown so much. I now feel calm and capable when facing difficult situations, rather than anxious or unsure. We learn practical, realistic self-defence, and have clear options for how to stay safe if ever we need it.

I would 100% recommend these classes to anyone — whether you want to get fit, build your confidence, or just take some valuable time out from everyday life.

"I always leave feeling stronger, fitter, and more confident."

Sam is an explosive, enthusiastic, and inspiring kickboxing teacher at our Northwood classes. He has real heart and a true passion for what he does, making him a fantastic role model. His lessons are fun, funny, and engaging.

He hasn't just taught my 9-year-old daughter, Jessie, the physical skills of the sport; he has also built her confidence over the last year and a half. What I appreciate most is how he inspires his students to apply the discipline, hard work, and focus of kickboxing to everyday life — which is precisely what our young people need today.

"I come away from each session feeling stronger, fitter, and more sure of myself."

Signing up to the adult classes at Diamond Kickboxing Northwood is genuinely one of the best decisions I've made. Every session is challenging but genuinely good fun, and they're set up to suit absolutely anyone — whether you're stepping onto the mats for the first time or you've trained before.

The coaches are fantastic — they really know their stuff, and they're endlessly supportive, always pushing you to go that little bit further and keep improving. They've built such a welcoming atmosphere that every class is a pleasure to be part of.

I come away from each session feeling stronger, fitter, and more sure of myself. I honestly couldn't recommend Diamond Kickboxing highly enough.
