Do you mean me?
Currently I'm just working as a travel nurse (I'm traveling with my husband visiting cities we're thinking of moving to). Once we settle down somewhere I hope to establish a client base so I can coach individuals in an office setting. For now, I just have a website and have coached a couple people via email/phone. I'm looking for more programs/certificates/classes on nutrition to build a more general knowledge base.
As far as coaching goes, I used the National Society of Health Coaches mainly because they're nationally recognized (credibility is a big concern for me), I heard good things about the program, and it was all online/self paced. Honestly, I wasn't super impressed with it; it involved a binder of notes and CD with review questions, etc. You have a year to take the certification quiz (which I thought was super easy) and that's it. The "members only" section on their website is non-existant. I haven't seen it updated once in the last couple years. No job postings, new resources, etc. So it was mildly disappointing, but I'm not sure of better programs out there. I heard that Integrative Nutrition was pretty good; their coaching is combined with nutrition courses. I was turned off by the commerciality of it (free iPads with signup, etc.).
I would just do some research on various programs and see what works best for you. I'd love to hear what you come up with! If you have any other questions just let me know!
