I've found the web courses offered are pretty good, on your time schedule and inexpensive if you are disciplined.\n\nFor coaching I've done The Coach Training Institute.\n\nCan't help you on the substance abuse because I believe that's a therapy issue and outside of the scope of coaching.\n\nYou could specialize in post-substance abuse coaching without an issue.\n\nI'd be happy to answer any other questions you may have.
