Hi there, I normally play with the 4.5 men league and guess I would consider myself a strong 4.0 or low 4.5. I'm interested in doing some coaching either on the side or perhaps as a full time job. I wonder what certification is required, how to get that, and any other pertinent info on how to become a tennis coach. I have about 12 books on tennis I've read cover to cover and have taken private lessons from about 6 different coaches so I have a feel for the coaching style and how it's usually done, but I want to step that up and do some workshops, get some certificates/documentation and the other licenses and such. Thanks.
