Those who already have coaches can use the site as an adjunct to their individual coaching. Age, gender, etc. People need different kinds of coaching at different stages of life. Anywhere from a few sessions to a year or more. It depends on the individual.
Some people come to coaching to deal with a specific issue or challenge.
Others like having a coach on board for the long-term as a sounding board, guide, and mentor. Each works on different things. A coach deals with the present and the future and gets a client into action based on what the client wants now. A psychologist concentrates on analyzing the past and how that might be affecting the individual s current state of being. Most coaches work at a discrete, individual level.
