I
Quiet Doubt
You don't ask for help. You don't show uncertainty. On the outside, you're decisive. No one sees it — but your confidence isn't as solid as it looks.
The Winning Mix
Leadership is decidedin the moments under pressure.
Two ways to work with us — a one-day Leadership Performance Lab at Queen’s Club in London, and a series of Friday-to-Sunday retreats — led by a high-performance tennis coach to ATP, WTA and Olympic players and a former senior executive at some of the world’s leading companies.
You don’t need to play tennis. The court is the mirror, not the test.
Start with reality
The gaps you knowyou have.
Most leaders know the theory. The gap is in the moment — when the data is incomplete, the room is watching, and the call is yours to make.
II
Fading Alignment
In the board meeting, the direction is accepted with little pushback. Afterwards, questions resurface in side conversations and follow through weakens, slowing progress without a clear challenge.
III
The Careful Team
Your team is good. Reliable. But they don't really push you. Meetings are smooth. Too smooth. You're not sure you're hearing the full story.
IV
The Recovery Gap
You're always on. Even when you stop working, your mind doesn't. You're not properly resting — but not thinking clearly either. You show up the next day already a bit drained.
We help you spot what’s really going on — and where to put your attention.
From the room
What participants sayafter the experience.
We protect the privacy of the people in the room. Quotes are shared with permission and lightly anonymized.
“I came expecting a workshop. I left with a clearer picture of how I actually behave when it matters — and what to do about it.”
“The court does in two hours what most off-sites cannot do in a weekend. There is nowhere to hide, and the feedback is exact.”
“David and Stefanie hold a very high standard without ever making it personal. That combination is rare.”
The method
Why we usea tennis court.
We don’t do roleplays. We use a court because it is an objective, physical test of decision making under pressure.
Research shows that when the pressure rises, people tend to fall back on established habits rather than conscious intentions. The court makes those habits visible.
You cannot bluff on a court. If you panic, the ball hits the fence. If you lose focus, the point ends.
The pressure is immediate. It reveals how you handle setbacks, project authority, regulate emotion, and sustain focus.
You leave with a clearer understanding of how you perform under pressure and some specific things to work on.
