My first was very average. No specialized attention, group of students a bit too large probably, I don't remember her lessons too well. She moved from the barn.
My second was fantastic. He taught me a lot and really helped my confidence. I learned to groom, tack up, lunge, AND ride from him. He helped my position a little but it still wasn't super good. I moved to a different country.
My longest running instructor was great. She taught me SO much. We worked mostly on Dressage, learned to do Driving, etc. I worked for her for a couple of years. Helped my confidence, my position, my body language on the ground, taught me how to train, put a lot of faith into me. I adored her. I want to go back to her. I might someday. I moved.
Took a couple of lessons with a Dressage instructor with good credentials, but didn't really "click" with her. Moved again.
Took one lesson with a H/J trainer. It was nice to be on a horse again but I didn't like the style of riding. She was okay. Super encouraging but the arena had a bunch of other horses in it which for what I was paying both to her and in gas to get there, I want an arena to myself. Got injured a few days after my first lesson and had to skip two, then just decided not to go back.
The instructor I have now is pretty good.. She's helping me with my position a lot. I have leg issues. I've only had 3 lessons with her. I would like to go back to my other trainer but I feel awkward about it for some reason. This one is young but talented, however doesn't have as much Dressage background as I'd like. I'm going to continue with her for a while, she's super friendly and fun to talk to and I feel like I can continue to learn from her for a while.
