Mdjst5,
I like your attitude. I am a mental skills coach in Texas. The idea that good coaches don't need help is like saying that parents don't want someone their kids like and respect to reiterate (in different words) the lessons they're teaching at home.
That said, the extent to which you'll want to use the school's consultant is dependent on her skill level and her time to spend with you to figure out your needs.
Great coaches are indeed great mental skills coaches, so if she's good, having this person on staff can be a great benefit to coaches and student-athletes.
I often hear people say "if only we could afford you" but the reality is they don't want to invest the time. At the college level, I am amazed that so many schools can afford to NOT have someone either full-time or consulting on a regular basis.
Best wishes, and let me know if I may be of any service to you.
