There are predators like this throughout the elite levels of sports like gymnastics, soccer, volleyball, softball, swimming and figure skating. So many parents and athletes trust these elite coaches and trainers so much that they are easily convinced that mental, verbal, physical and sexual abuse is part of the process.
Dear parents, if a coach or trainer tries to convince you that what they need to do with your athlete needs to be done where it is only the two of them then you need to figure out WTF is really going on. Underage kids should NEVER be sharing a hotel room with their students. Underage kids should NEVER be undergoing any type of medical procedure that you are not explicitly informed of prior to it happening. Yes, there are a ton of meddling parents that interrupt and make things more difficult but you need to be diligent in understanding what is happening with your kid.
