For people schooling, this barn may pull you in with the large number of well trained schooling horses and frequent appearances on the unrated show circuit. For boarders, it's often the lower price of board.
I can at the very least say, people who grow up riding with Tam sure do tend to learn how to stay on a horse. That said, people learn to ride well in plenty of other places. Tam is a very unpleasant person to work with and as mentioned by other commenters, can be VERY cruel to both horses and riders. I recall many times in which she made the horse I rode stay in his bridle overnight for picking his head up, which caused sores on his mouth where the bit (a rather sharp double twisted snaffle) had cut into his mouth. Naturally, after the sores were there, he would REALLY pick his head up when anything pulled on his mouth when he wasn't expecting (you know, because he had open sores and was in pain). Her response was to keep the bridle on longer and make him run in the round pin. Not the sort of logic horses understand.
