Welcome to the T.S.I. Junior Section

Fun and Learning all in one
Our teaching methods include a variety of games and goal-oriented tasks that allow for kids to keep their focus for as long as possible while learning and enjoying the game. The early stages of child’s learning process are crucial to their development and future potential. Having incorrect technique can be detrimental to their tennis game and can increase the risk of injury. At Tennis School International we put our best efforts into making sure that the proper balance of technique and tactics is being trained while the kids have fun and enjoy the game of tennis.

About our High Performance & Accelerator
Programs
This training is specialized for players wanting to compete or already competing in tournaments and/or leagues. Coach Sebastian Zapata will be overseeing all the trainings, with Rudi Visser- a former ATP/WTA Coach and ITF travelling coach, contributing as a mentor, offering guidance and sharing international experience to enhance the coaching program. The goal of TSI in its simplest terms, is to help players become the best player they can be, while fostering a set of core values that will not only help them on the tennis court, but in any of their future endeavours.
Special attention will also be placed on developing optimal Biomechanics (technique) and tactical elements. We believe finding the right balance of these two elements is key. Benefits of optimal biomechanics include: Reducing the risk of injury and better performance by improving power, consistency and efficiency – from a technical point of view.
