Congratulations on looking into becoming a Life Coach!
Have you tried googling "Executive Coaching and Life Coaching?" Another way to research training programs is to find Life Coaches online that you admire and look at their bios.
Also you can go to the Life Coaching site here on Bella. Here's the link:
Bellaonline Life Coaching Site. On the main page look at the "Subjects" on the left hand side of the page. Look for "Life Coaches" and click on the link. Then visit the websites of those you find interesting and take a look at their credentials.
Good Luck and Keep in Touch!
