Heh. I didn't even know there were specialty certifications in massage. I really don't know, I just lucked out - my precious LMT doesn't have any that I know of, and he actually told me that many of the techniques he uses were invented by his wife, not learned in school or seminars. Mostly you can tell from their ads whether they specialize in sports massage or in a relaxation, spa-type experience. Ask around for who works on top athletes in your area. My experience is that getting any individual muscle to release is not that complicated, it's working them in the proper sequence that very few LMTs seem to understand.
