John came highly recommended by the trainer at my club. I had a sports injury from weight lifting. Basically I had damaged my back. I could barely function, but following one intensive session with John he had me back in good shape. Following on from this John has coached me on sports nutrition and advised on the correct supplementation to achieve my goals. I could not recommend John and the Dublin Performance Institute highly enough.

I had chronic back pain/sciatica for over 5 years and John was able to relieve the pain and prescribe an exercise regimen that strengthened me to the point where I am now pain free for the past four years. I recommend him to anyone in a similar situation.

I have visited John on a number of occasions with ailments such as back pains, tight hamstrings and groin injuries etc. John has sorted me out after a few visits and I have recommended him to my friends. He is also the right man if you are looking for tips on healthy eating and losing weight.
