about
Miguel Coelho
I have been coaching tennis since 1997, across clubs, academies, and national programs in Portugal, Spain, and the United States. In that time I have worked with players at every stage of development, from children picking up a racket for the first time to professionals competing on the ATP, WTA, and ITF tours.
What changed over more than two decades was not my commitment to the work but my understanding of it. The more I saw at the highest levels of the game, the clearer it became that most of what drives decision-making in junior tennis has very little to do with how athletes actually develop. I went back to study that gap formally.
I hold a master’s degree in high-performance tennis and a PhD from the University of Arizona, and my current research focuses on the science of long-term athletic development.
I am a member of the USTA Southwest Coaches Commission and contribute to coach education at the national level. Junior Elite Tennis is the direct expression of everything that work has taught me: that players develop best when every part of their preparation is connected, honest, and built around who they actually are rather than a program template.
The most dangerous assumption in junior tennis is that more is better. More practice. More tournaments. More hours on the court. The research says otherwise. Experience says otherwise. And yet it remains the default.
What I believe
Convictions earned
over more than two decades
on specialization
Early specialization is one of the most reliably documented paths to burnout and overuse injury in young athletes. The research on this is consistent. The practice inside most junior programs is not.
on integration
Tennis, physical preparation, mental performance, and injury prevention interact in ways that determine a player’s ceiling. Treating them as separate subjects is one of the most common and costly mistakes in junior development.
on competition
Most junior players compete too often and reflect too little. A competition calendar should serve the development plan. When it is the other way around, the player pays for it over time.
on honesty
Families invest a great deal in their player’s development. That investment deserves a straight answer. I tell you what I actually see, including when something is not working and when a different path would serve the player better.
on player agency
Before I work with any player, I speak with them directly. Development without genuine buy-in from the player is just management. That is not what this is.
who is this for
I work with serious junior players aged 12 to 18 and the families behind them. My clients compete at sectional, national, or ITF level. They are not looking for another training program. They are looking for a coherent system, an outside perspective, and someone willing to be honest about where things stand. I take on a small number of clients each year, in the United States and internationally.
The best place to start is an honest look.
The development audit gives you a clear, outside perspective on where your player actually stands. A written report, a 90-minute debrief, and a concrete roadmap. No strings attached.
