Therapy is a remedial modality which supports people to overcome emotional trauma. The focus is usually on exploring past psychological reactive behaviours, and providing coping mechanisms and solutions to the underlying emotional trauma. Therapists help to diagnose issues, and advice is often given on how to heal mental health challenges.
In contrast, coaching is a proactive, forward-focused process which aims to make you aware of patterns and behaviours, and progressively solve them before they come up. The client chooses what they’re willing to explore, reflect on, and work through. Coaches don’t diagnose, advise, or prescribe anything, because the principle of coaching is that the client is the master of his/her own life, and is fully capable of generating their own solutions.
