We have 2 coaches, who are also the head coaches/owners, that only coach the level 10s. It's possible they work with the 9's sometimes, but my dd is far from that level so I'm not sure, but I know they are considered the level 10 coaches. We have 1 bars and vault coach that coaches the 7-9s. He also sometimes works with the lower levels, although that has been less and less. We have 1 beam and floor coach that only works with the 7-9s. We also have another beam and floor coach that is a new, just out of college, former gymnast that has been working with the 7s, So, I guess 5 coaches that work with the optionals. We also have 2 coaches that do levels 3-5, although they sometimes help with the 7s and another coach that does the level 2s. I think we have in the neighborhood of 45-50 total optionals.
