No, the instructor I had the longest was fine but I found out she would talk behind my back saying how bad I was, and how she didn't want to teach me anything new because I was nervous. No kidding I was nervous her horses are tanks that pull, buck, rear and bolt! Plus isn't everyone nervous to learn to jump or after a serious accident?
Looking bad I was stupid for trusting her judgement as much as I did, all the preventable injuries, lame horses, never learned anything new.
After a fun day kind of clinic thing the guest instructor picked at me the whole time, you can't post, your no good at this not once did she say how to fix it. I was just couldn't do anything right (well that's putting it nicely, as she used a few different words). I got off the horse, untacked her, told them I wasn't there to be belitted and I wanted my money back.
Never went back, I still talk to her and we're on good terms but I don't trust her judgement with horses in care, tack choices, in horses period. Too many trips to the ER say, years of ownership don't mean you know whats best. (This doesn't mean I know better, it means I have other people that I trust their opinions a lot more, such as vet, farrier, and more)
