Highly recommend David. He is incredibly patient, respectful, and professional. The way he works with my son, focusing on technique, discipline, and confidence, really stands out. My son has been doing boxing for 4 years and has finally found the right trainer—someone who shows respect in return. After a past experience where that level of respect wasn’t always reciprocated, training with David has been a very welcoming and positive change. You can already see the difference, not just in skill but in confidence as well from my son.Posted on Google![]()

David is a dedicated and experienced trainer. I have been training with David for the last 9 months and found that very effective and helpful. David tailors his training to suit client needs and what works best for them. The best thing is he comes to you to train in your own environment which makes it easier to complete scheduled training. The boxing classes are beneficial and improve fitness and I would definitely recommend Goliath for your training sessions.Posted on Google![]()

My child has been doing PT sessions with David from Goliath Performance and the results have been fantastic. Not only have they been improving their fitness and boxing skills, but I’ve also noticed a huge boost in their confidence. David is patient, motivating, and really knows how to connect with young people. He keeps the sessions fun while still pushing them to improve, which has made a big difference in their progress. The mobile training setup is also really convenient and takes away the pressure of a gym environment. It’s been great seeing the positive impact the sessions are having — both physically and mentally. Highly recommend Goliath Performance to anyone looking for a supportive and professional boxing coach.Posted on Google![]()

My experience has been great. David is punctual and friendly, he easily engages you during the session and is very knowledgeable. David also incorporated my 11 year old son and helped with his functional strength and confidence building with boxing.Posted on Google![]()

Brilliant trainer. My 11-year-old son plays football at a high level and David understands exactly how to push young athletes while keeping sessions positive and motivating. Fantastic experience.
