Holding therapy was originally made available through "Mothering Centres" in the US and the UK. However we have been unable to determine whether those centres still exist or whether any other organisations are currently providing holding therapy.
According to Simpson et al (2005)
'”Holding therapy is performed by the mother with support from the father or other family members under close supervision and facilitation of a trained therapist”. However we have been unable to identify the qualifications or credentials of the therapist.
