Cold Laser
I have had Cold Laser training under my other health care license. Much reasoning behind the decision to use cold laser for an issue is "diagnosis" bound. Currently I do not offer it in my office, and am not sure I ever would. I don't have anything against it, but I am not wholly convinced that it is the right modality for the type of people I see. As I recall, the cost of a good unit is not cheap either.
I am not sure if I would offer it soley under an MT license. I don't know what the state regulations are for that either.
For training, you can look at the Erchonia site. http://www.erchonia.com/seminars as I do know that this particular company trains across the country.
