The JSTA Philosophy

Many athletes train hard for years without seeing proportional progress. The issue is rarely effort. It is decision-making, structure, and understanding what to develop and why. JSTA exists to solve that gap.”


JOAO SILVERIO - HEAD COACH, JSTA

A system built on four pillars

Real progress doesn't come from isolated drills. It comes from a structured, intentional approach to every dimension of the game.

01

Technical

Precision mechanics built to hold under pressure — not just in practice.

02

Tactical

Pattern recognition and decision-making that translates directly to match play.

03

Mental

Emotional resilience and focus built into every session, not treated as an afterthought.

04

Physical

Movement, athleticism, and endurance developed in full context with the game.

Joao Silverio

High-Performance Tennis Coach

Meet the coach

No. 1 junior in Portugal. National Team representative. ATP and ITF professional circuit competitor. Joao Silverio combines elite playing experience with international coaching exposure at the highest levels of the sport — including professional players Gastão Elias (ATP 57), Pedro Sousa (ATP 99), and João Domingues (ATP 150), both Olympians — and travel to Grand Slam and ATP tournaments as a coach.

Over the last decade, he led high-performance programs across Europe and Asia, guiding athletes to NCAA scholarships, ITF rankings, and national titles. He now brings that methodology to Boca Raton, Florida — working with juniors and adults who seek real, measurable progress through a personalized development plan.

What Players & Families Are Saying

Results speak for themselves

"Trusting Joao with my daughter's tennis development has been one of the best decisions we've made as a family. He pays attention to her mindset, her decision-making, and her confidence. Every session has a clear purpose, and the progress is visible — not just in technique, but in how she carries herself on court."

— Camilla • Parent, Junior Development

"He didn't just tell me how to fix my shots — he taught me why things happen under pressure and how to stay calm, think clearly, and trust my game. Now, when I compete, I feel prepared."

— Alex • Competitive Junior

"He immediately identified the habits that were holding me back and created a plan tailored specifically to my game and goals. Each session feels intentional, challenging, and smarter than anything I've experienced before."

— Vincent • Adult, Elite Performance

These are great when you need a little boost in the afternoon. These make me feel alert and revived but not jittery.
