Hi, I can tell you that over the years, hundreds of folks have told me how incredibly helpful their DB coach has been...
linz, while Karen does work for The Divorce Busting Center, I would say that pretty much everyone I know who has obtained a coach has received appropriate and very valuable support and information to help move themselves forward as well as likely helping move them towards R.
I have seen some people question certain advice, yet from my perspective, the advice IS VERY APPROPRIATE for that unique sitch.
If you can afford it, I would highly recommend it. Like many things, the value you receive will far exceed any capital cost.
