This might be a long post …
In general I agree with scribbler about his evaluation of the trainer. But as I tried to say before there are so many things which need to be right to make it to the top and this evaluation only looks at one aspect.
I have no experience in bringing up kids to the top in riding but two of my kids were ranked internationally in tennis and I do believe a lot of things I learned during this trip might be useful for riding too….
I personally believe that in order to make it to the top you need to keep horse and rider healthy until they are ready to perform at the top. I have seen a lot of very talented tennis players who were worn out (health wise and mentally) when they were 16 or 17.
In order to achieve that the parent needs to protect the child (and the horse) in my experience kids with protecting parents lasted longer.
The really most important thing!!! The child (and the horse) need a very very solid foundation. It doesn’t make sense to put a child on a schoolmaster if the foundations and the knowledge of the foundation are not solid, because it’s easy to cheat and it will catch you at one point in your career. But still she will need a schoolmaster to learn to feel how it’s done right!
You need to know what you are doing and why you are doing it in order to avoid huge problems in the future… My children were extremly lucky because the owner of the tennis facility had big dreams for his daughter and had found a Russian coach who had moved to Hamburg and who was a Davis cup coach for Russia at one point.
And to keep the cost down he offered clinics with him for other kids as well. This coach was really into the right technique and I still believe without him my kids would not have gone anywhere….
so my advice even if you train with this trainer who is pretty unknown try to organize clinics with big names in your barn. And I mean real big names…. Think about Joh Hinneman ( I adore him) maybe Sabine Shut Kerry (She seems to be really nice) Maybe Kelly Layne. ( she is really really nice ) Of course I would prefer the German trainers because both of them know the right foundation.
And please if you read books stick with the Richtlinien für Reiten und Fahren. It tells you everything you need and if you simply do what it says you will be fine…
Then try to connect and develope a relationship with these famous trainers but be a bit careful though because their main business will be to sell you a horse…keep this in mind…
But they can help you in many many ways if they like you…. They know everybody and they can maybe recommend your daughter to somebody who might help her to develope her riding skills. Like an internship in her school vacations…
Not sure from which country you are (maybe Great Britain) but there are always amazing possibilities in Europe so you could spend some time there…
Regarding this trainer…. If the location is convenient for you and if your daughter likes her and if she is experienced with young horses (at this point the most important factor) go for it. you could train with her for a while and see how it goes….
But you need to be prepared to watch any progress and evaluate all the time whether you are on your way towards your goal….
With a goal as high as yours you have to be extra careful…
And just saying my kids were the reason why I moved to the US. At one point we decided to move them to Nick Bollitieri in Bradenton. So you need to keep a potential move in mind.
During the journey you will learn a lot and it will be fun to do things with your daughter !! But you need to learn first that you are the only person who acts in the interest of your daughter and your horse. everybody else is only interested in the money. so you do need to protect them like crazy!!!
Oh and some information for you, I have no idea whether it’s useful for you but remember I told you collect as much information as possible because at one point you might need the info or the connection.
Not sure whether you know but Joh Hinneman has family in the US and I believe his granddaughter is only a couple of years older than your daughter and she is riding very successful. I believe they just moved from California to somewhere like the Carolina’s (not sure about it but you can find out) his daughter in Law runs a dressage barn.
So maybe you could inquire about clinics or something like an extended stay at their facility. Maybe I am horrible but I would take this as a opportunity to learn how they manage their daughter, to see different high level horses and maybe even create a relationship with the Hinneman family…
Riding is a hands on sport online classes are only second best way to learn… nothing beats to be in the middle of a professional setting…
Oh and something else stay organized about everything you learn, maybe keep a diary where you write down good and bad experiences and connections. Also write down your goals and stations you need to reach in order to reach your final goal and check regularly whether you are on the right path.
I assume some people would take money for this advice . but I wish you the best of luck for your daughter and your family. Remember don’t ruin yourself financially because sport is not worth it, but otherwise have fun on the journey
