Agreed, there are some truly terrible coaches out there. It’s actually one of the reasons I “turned pro”. I knew I could provide a valuable service and get compensated appropriately while retaining my moral center.
As a practitioner, I think it’s important to “eat one’s own dog food” so I have employed several personal coaches in my own life over the course of several years. Even those of us who should know better (AKA: me) have paid ghastly amounts to some of these charlatans.
I’ve worked with five or so different people over the years, two or three of them were worth what they charged and one of the them was off the chart brilliant. He charged the most by far and it was worth it.
