The tatoos really say nothing about the counselor's character. Truly. And what you what for your son is a caring, fun, gentle counselor. Talk to the counselor first, and if you have a reason to be concerned with him AS A PERSON, then ask for a change. But not based on tatoos. You may deny your son the counselor he really needs this summer if you do.
