For ANYONE looking to understand the power of coaching and how it works, this is THE book to own. Co-active coaching provides a beautiful model that's broad enough to use with all of your coaching clients and deep enough to enable truly powerful coaching. The book is based on the cirriculum of The Coaches Training Institute coach training program, and even though I earned my CPCC (certified professional co-active coach)certification several years ago, I continue to dog-ear, underline, and highlight this book every time I take it from my bookcase. It gets better with each new read!
