Why partner organisations choose the 359 system
When tennis quality depends on individual coaches, growth is fragile. The 359 Method delivers a shared coaching language, a unified development logic and predictable quality — across courts, coaches and seasons.
Shared method — every coach works from the same Fit · Fun · Focus framework, so quality doesn't depend on personality.
Visible progression — players, parents and partners see structured development — not just lessons.
Operational continuity — when a coach changes, the system stays. Members keep their development path.
Many organisations think they have it covered
There are coaches. There's a schedule. Lessons are being taught. But that's not the same as a system.
Quality varies per coach — and nobody notices until the wrong one leaves
Growth depends on individuals, not on structure
There is no uniform method, no quality framework, no development logic
Differentiation is temporary — because it's based on people, not on a system
What happens if this continues
Quality keeps fluctuating — depending on who happens to be coaching
Growth remains fragile. One departing coach can disrupt an entire season
Scalability stays limited, because there's no transferable system underneath
Competitors who do build structurally create an advantage that becomes harder to close
This isn't failure. It's the result of growth without a system.
The choice isn't whether to develop
Every organisation develops — consciously or not. The question is whether you do it structurally, or leave it to chance.
If you're responsible for the quality of your tennis offering, the growth of your coaches, or the positioning of your organisation — this is the moment to choose a system that makes that possible.
We develop people. Sport is the vehicle.
The 359 Method is not a lesson package. It is a complete development system — with a uniform way of working, coach education pathway, quality framework and proven structure. Developed and refined since 2005 at the National Tennis Centre in Amstelveen.

Developed and proven at NTC Amstelveen
359.tennis is the birthplace of the 359® Method — the environment where the system has been developed, tested and refined in daily practice since 2005. What works here is transferable to your organisation.
Partner of the ABN AMRO OPEN
For the ABN AMRO OPEN, 359 developed a scalable clinic concept that works for public audiences, corporates, and VIP relations. We have been executing this programme ourselves for over 10 years. From 10 to 120 participants per session. A new group every 30 minutes. This is not a one-off clinic — it's a proven system for impact at scale.
Work with the 359 MethodOrganisations without a system remain dependent on people. People leave, change, differ. Without a system, quality stays vulnerable — and growth becomes a matter of luck.
This page is an application of Fit · Fun · Focus for organisations. The 359 Method stays the same; the application changes by audience.
Learn more about the 359 MethodAdministrative support for tennis coaches and academies
As a freelance tennis coach or tennis academy owner, you likely spend more time on administration than on coaching. Student registration, scheduling, invoicing, parent communication — it takes hours every week that you'd rather spend on court.
Through the Operator Model, 359.tennis provides complete operational support for tennis coaches and academies. We handle the business operations — from planning and administration to billing and parent communication. You focus on what you do best: coaching and developing players.
Whether you're an independent tennis instructor looking to outsource scheduling and bookkeeping, a tennis school without dedicated office staff, or a club looking to professionalise its tennis programme — 359.tennis has a partnership model that fits.
