According to this article...
SO SHARP. | Extol Magazine
The trainer is a friend of his that is married to an ex-Ladybird he introduced him to. He also coached Marissa and Michelle from the age of 3, through Dazzlers, and into UofL. I think the article also talks about the % of Dazzlers that end up being Ladybirds.
I do respect the fact that he doesn't cut girls during tryouts (which would explain why Gabi is there). In either the Extol article or somewhere else he talks about how girls are hard enough on each other so if he sees a girl that works hard but doesn't have technique, he will take her anyway because of her ethic.
We literally count down the days until the next episode is on.
