Hi, I'd like to help you with your question.
If you know a person or organization that has used one, a personal reference is your best choice. Other than that, you can try a search on line. Here is a good place to start:
The internet also lists personal websites of life coaches so you can see what they have to offer before you settle on one.
You can also contact local companies and see if they have used a life coach before. Also, check out your local seminars. Life coaches often give seminars to develop business. That way, you can learn about them first hand before hiring them.
I hope this has helped you,Kate
