Clerkin Psychology Services

Clerkin Psychology Services Ltd was formed by Dr Colin Clerkin in 2001. We offer psychological assessment, therapy, coaching and training in response to needs identified by our clients, who clearly have valued the high standards of service offered as we have gone from strength to strength over the years.

In 2017, Dr Maria Knapp, HCPC-registered clinical psychologist, joined the team on a part-time basis. Like Colin, Maria offers psychological assessment and therapy for children and adults.

The team is supported by Ailsa Bourne, Dr Clerkin’s Personal Assistant. Ailsa will be most callers’ first point of contact with the team. She will manage your enquiry thoughtfully and confidentially.
