Hi, my name is Alonso Leon, I’m from Chile and I’m currently working in Spain. I have been working in high performance/competition in different academies in Spain, Chile, and Australia. I have plenty of experience with junior development and high performance.
I’m extremely passionate and professional, I really care about what I do and go above and beyond to help my students improve both on and off the court. I pay a lot of attention to the technical aspects of tennis as well as the mental part of the game.
