I learned NH as kind of a basic model of horse training back in the US (where I'm from) and it's always worked well for me. No one I personally know here uses those methods as a baseline (some of them could use it, but nevermind). There is, however, an NH trainer near where my horse is kept at livery but I've not done more than peruse her website. She has "branded" her method of horse training, given it a silly made-up name, and you can take courses at her barn where you become certified in her special system. That brings out the skeptic in me and puts me off. Can't you just call it training? Why does it need a daft brand name? For all I know, she might be very good and I'm being unreasonably grumpy and judgmental.
There's another NH-style trainer in Fife who has a website that clearly explains his training philosophy and doesn't give it any silly made-up names. I find that far more appealing.
