A Counsellor has specific training in counselling theory and skills, as well as some clinical experience. This practitioner would usually conduct short- and medium-term work, either focusing on a particular aspect of the person’s life or acting as an active and empathetic listener to accompany someone undergoing trying times with patience and positive regard.
A Psychotherapist is concerned with the analysis (and the meaning) of life as it is experienced and managed by a person. This professional has trained at a post-graduate level for many years and would have had about three years practice experience prior to full qualification. As this work implies significant complexity and depth, a long-term process is usually required.
A Coach could have a background in a more dynamic milieu like the behavioral approaches to human psychology, business or sports, and it generally appeals to the working environment due to its pragmatic approach to resolve issues. It tends to be short-term and is directed toward particular outcomes.
