When comparing therapists, look at their appointment format, location and whether their profile describes experience relevant to the support you are looking for. Qualifications and registrations are shown only where a therapist manages their own listing, and we do not verify them, so check accreditation with the relevant professional body as well.
Marshall has one EMDR therapist listed on this page, with a profile that lists professional registration details.
Common qualification details listed on Marshall profiles include BACP Accredited and EMDR UK/Europe Accredited. Registration details mentioned include BACP and EMDR.
It is also sensible to ask about availability, fees, appointment format and whether EMDR therapy is appropriate for your situation before starting work together.
