When comparing therapists, look at their qualifications, professional registrations, appointment format and whether their profile describes experience relevant to the support you are looking for.
Bolton has one EMDR therapist listed on this page, with a profile that includes additional detail beyond the basic listing information and lists professional registration details.
Common qualification details listed on Bolton profiles include Advanced Cognitive Behavioural Therapy, BA Psychology, Clinical Hypnosis and MSc Forensic Psychology. Registration details mentioned include BPS (250793), BSCH (6919) and HCPC (PYL27994).
It is also sensible to ask about availability, fees, appointment format and whether EMDR therapy is appropriate for your situation before starting work together.
