I don't have too much advice for you really about the programs you mentioned. Life Coaching as of now is not regulated, as therapy, psychiatry, etc is. And, life coaching is not medical advice.

My coaching is a bit different from traditional coaching. As it has evolved, I most often offer it to students who are pursuing some creative endeavor with me (like guitar, piano, voice, music composition, writing, etc). They want to be more creative, and, say, sing in public, write, create, perform, become the next "American Idol," etc. And yet, they have life issues related to this which impede their progress. That's where most of the coaching I do comes in. Occasionally I have a coaching client who is strictly a coaching client and not pursuing "creative endeavors" (though just as all things are "spiritual," so all things involve creativity!)

I have not attended or pursued a formal life coaching program. I offer my experience to students which comes from a unique background which includes: a unique childhood with two uber-intellectual parents, a lifetime of reading and spiritual search, being a writer and performer, and a unique artistic and literary background. This background includes education (on bachelors and masters coursework level) as well as practical experience in a variety of genres in education and the arts. I have not done too much research into various life coaching programs since my work as a coach has grown out of what I describe in the paragraphs above. Formal life coaching programs have not seemed necessary to me.

I have heard students say my ideas sound like "The Secret" though I have not read/seen much about this. I do think Course in Miracles is very healthy, and any life coaching program which features Course in Miracles or New Thought type ideas would be good.

Clients come from all sorts of backgrounds, and one must be able to work with all, from Christian fundamentalists to more liberal and intellectual sorts. I try to listen, be able to take in a lot of information, and quickly devise (along with the client) a "plan" (which can change every day or every minute if necessary). It is the goal of this plan to get them where they want to go (along with help from the Universe and their higher self),

Ultimately, it is the goal of my coaching that the client will become their own "coach" and listen to their inner coach.

Of course, there are many other things I do and believe, but I hope that this "in a nutshell" information helps. Any programs which recommend this sort of approach I would recommend.

Peace...
