I met a 15-year-old in Warsaw and stayed six years, through a Roland Garros title and a World No. 4 ranking. Since then: WTA, ATP, juniors turning professional. What decides it for me is the challenge, not the tour.
Bars mark the exact period I worked with each athlete. Numbers are the best ranking reached inside that window — not lifetime peaks. Recent years are shown at a larger scale than older ones.

The drive stays theirs.
I give players room to genuinely want it. My job is to aim the drive, not supply it — the decisions that hold up under pressure are the ones the athlete owns.
Hire people who know more than you.
Psychology, fitness, physio, analysis — each with a defined role and a real say in their domain. No competing voices, one direction, no ego in the room.
Nothing important is left to a hunch.
Load, recovery, scheduling, the patterns in a match — all of it feeds the plan, so the big calls get made on what is actually happening. The numbers inform the decision. The coach still makes it.
Four ways in.
Strategy call
One focused 60-minute video call on a match, a technical problem or a development decision. You leave with a clear next step and an honest read on where the player stands.
Match video analysis
Send match or practice footage. You get an annotated breakdown: the patterns costing points, ranked by what to fix first, and the strengths worth building the game around.
Monthly remote advisory
A coach in your corner between tournaments — regular calls, schedule and load input, periodization, and someone to call before the decisions that matter.
Coach mentorship
The method first-hand: taking juniors into the pro game, periodization that survives a tour calendar, and how to build a high-performance team around a player.
Scope and fee agreed per engagement. Tell me the problem first.
Every result on that chart has someone else's name on the trophy.
That's the job, and I'd take it again. But the method travels — and it works just as well on your player as it did on mine.
