Great! Thank you for the prompt and clear reply.Entering it as non clinical volunteering is the best choice, assuming you were not paid extra after taking on Head Coach duties, if you do not already have a lot of hours in that category. It could also be entered as Teaching (of which coaching is a form, in general, or Extracurricular). Leadership would apply only for the time you were in charge of other coaches. If that was the case, and you were not paid, you can add that designation to the title of the Volunteer space, to make clear the experience covers more than one category.
