When we turn our bodies over to a healer—be it a physician or a massage therapist or an acupuncturist—we like seeing letters after their names. The MDs, the CMTs, the LAcs, give us a sense of security. We trust degrees, and the implications of knowledge and skill they represent. But in the field of bodywork, those initials are harder to interpret. Regulations vary widely from state to state, and often from school to school. And because many practitioners of newer modalities are still attempting to formalize the establishment of cross-national standards, many are not and cannot be certified. Even so, some schools have specific requirements that ensure a certain level of training. Some of the most common follow.
