No. The client may need the life coach in order to maximize an opportunity or accelerate their personal growth, yet not be dependent on the life coach. Anyone who has big goals can benefit from the structure, advice, and support of an accredited life coach, so in that sense, yes, a life coach is needed. As far as creating an emotional or psychological dependency, not to worry. Life coaches work with people who are healthy and successful on their own. Life coaches do not resolve therapy issues. If you start to feel dependent on your life coach, get a therapist!
