And please know that anyone who has integrity will not be offended by your queries regarding what will unfold during a session or event, or what kind of training they have undertaken.
In this wonderful time of transparency we are able to get a feel for who someone is quite easily. Websites, blogs, Facebook pages and profiles allow us to easily know who we'll be dealing with.
So, before you book a session with someone please check them out. If they operate under a business name make sure the business is listed (and owned by them) and they pay tax on the income the business generates. Go to their website to educate yourself regarding what they offer. Check out their Facebook pages and profiles. That way you'll know who you're dealing with.
Due diligence can make the difference between a successful session or a disappointing one.
