This brings up the interesting question of how coaches break into the field and move up. Someone like Orser had an unusual amount of luck: YuNa pulled him up the ladder quite a few rungs by "proposing" to him and then becoming one of the best skaters ever. What he gave her was impressive, but she also advanced his career with some uncanny idea that this was the coach who would get her through the Olympics.
Sato and Dunjen are also relatively new coaches, though I gather that Dunjen became a coach before Yuka did. (In fact, he coached Yuka.) I'm sure her record as a world champion, and maybe her father's position in the coaching world, were great selling points that made her attractive to skaters.
As for coaches who made it to the top ranks because (as bebevia says) they had a "random baby" who remained with them even when great talent revealed itself, I'd put Robin Wagner (Sarah Hughes' coach but not, interestingly, Emily's) and Linda Leaver, who coached no one else but Brian Boitano from his childhood through his pro career.
