Hi HollyMel. I'm not sure exactly what you mean. In order to practice as a Vodder Therapist you have to be trained by a Vodder approved Training Provider and then you have to go back for a Training Review day every 2 years to have your technique re-approved and correct any bad habits you might have developed! Obviously you would need the appropriate insurance as well. Hope that is helpful. You can find out more from
