Group Coaching and Therapy can be as effective as one-to-one coaching and therapy sessions. It has the advantage of a broader perspective and understanding of your needs, behaviours, symptoms, weaknesses and strengths as revealed by another group member.
The group is also a safe space to exercise opening up, becoming vulnerable and getting the sense of how powerful is to own your fears and weaknesses so that they don't lead your life.
You are putting yourself on a path of consistency, where you are making the right decisions, taking the right actions, following the right plan and continually measuring your progress.
It is also the most cost-effective.
