I hate to even say this, but I hate it when female all star cheerleaders have visible tattoos on their stomach, side and/or back. I don't think they should be visible in your all star, crop top uniform. I don't particularly care if you have one on your ankle that I can see, and that probably makes me sound crazier. I just know that if we are trying to have our sport respected, having a giant tattoo down your side from boob to hip bone doesn't necessarily scream All-American athlete.
All that to say, I could care less if you have tattoos as long as you are a good coach and not wearing a half top on an Open team.
This, of course, is just my personal preference and I wouldn't pull my kid from a gym that had great coaches - tattoos or not.
