I strongly disagree.
In my experience, most coaches are highly trained and talented individuals. They truly care about people and take their professional responsibilities very seriously. They are perceptive, active listeners who ask penetrating questions that help their clients make positive choices. Their clients have more rewarding careers, create stronger personal relationships and live happier and more fulfilling lives as a result of their skills and experience. Like any profession, I'm sure that there are both good and bad Life Coaches, but the bad ones are the exception rather than the rule.
Some people discount coaches because our industry is not regulated; we receive certification from industry associations rather than licenses from a government agency. While this is true, most coaches go through rigorous training to achieve certification as well as needing both classroom and practical experience to receive the highest levels of certification. Licensure of coaches is probably coming, but don't discount the efficacy of professional coaches because it isn't currently required.
The best way to ensure that your coach is effective is to look for testimonials and reviews from their clients. The best coaches change lives and their clients are happy to share their stories with prospective clients.
I call myself a Life and Relationship Coach. You can call me whatever you want, but if you are stuck or struggling with some aspect of your life, be sure to call. I can help you get unstuck and moving toward a happier and more fulfilling life.
