Each professional has a work modality; however, when you choose a therapist, make sure that they have sufficient education and experience:
Your mental health professional should have:
A background in Psychology, so that they have an affinity with the various psychopathology and a solid theoretical base.
A Masters degree in Counseling or Psychology, to stand for an in depth understanding of their area of interest, ie Child Psychology, or in my case, Clinical Psychology (the modality that deals with human psychopathology and suffering).
The above provide the practitioner with theoretical knowledge of the field. The practitioner has to have a solid education in Psychotherapy: practicing and understanding the actual work of a psychotherapist. I chose for an in depth 4 year Psychotherapy training were the focus was on actual face to face client work.
My approach describes is an integration between Existential psychotherapy, Gestalt Psychotherapy and Cognitive Behavioral tools.
