Most coaches who have joined J4K at one time already had their own GK schools going, however they realised the importance of being part of an International team. Not only to tap into our collective goalkeeping knowledge but to also tap into our International contact base.
Most goalkeeper students are now educated and want to be a part of a GK school that can offer them career opportunities, either to get scholarships or trials with professional clubs. If you cannot offer this and a competitor opens in your area who can offer these services for their students you will be in big trouble. So coaches also join J4K because of our PROVEN track record in helping our students.
And lastly credibility. Even if you have a great name as a GK coach but you are only based locally in your area, this limits you as a coach. But if you join J4K, you become part of an International team, so you go from being a local GK Schools, to an International GK Schools with International connections. It does not matter who you are, this adds serious credibility to you, your GK Schools and your CV.
