I started working with Jason when I was 21. I had been playing professionally since I was 17, my ranking was 940 and I really wanted to quit tennis, because it was just not working out for me.

In just a couple of months working with Jason, my ranking went up to 299.

I started to understand how little I knew about tennis before I worked with Jason.

My technique was completely off, I didn’t have a good strategy, and my mental game was very poor too.

But Jason taught all of that to me. The best thing about Jason is that everything he explains and teaches on the tennis court is very simple.

You can see very clearly why it’s going to work, and then it does!

He is always very positive, even if you make mistakes, he makes you feel good about yourself and he will make you remember all your good shots and that will make you stronger.

Jason constantly looks for ways to improve my tennis, and no matter how well I’m playing, he can always find something to work on and always makes me better.

I’ve worked with some of the best coaches in the world, but none of them have helped me improve as much as Jason has.
