No need to shut anything down here. Alanna's reputation will grow and flourish as her students excel during school and tournament ball. This is how it works, IMHO: you watch a game, there is a pitcher out on the mound who has confidence, throws well, frustrates hitters, and most of all "looks strong". So you ask around, " who is that girl's pitching coach?" Then someone will say, "Oh, she is another one of those "******" students, or, "she goes to "**********".
This scenario repeats itself. That's how my DD ended up with the coach she has now. It sounds like Alanna has or will get that reputation too. It won't take long.
