"Mastery in Coaching, the sixth book in the AC series, skilfully draws upon a rich body of knowledge, demonstrating that coaching works. It is a significant contribution to the profession, based on the premise that mastery is not a destination in itself, but a journey of lifelong learning."
Katherine Tulpa, CEO and Co-founder, Association for Coaching
"While this book is entitled Mastery in Coaching: A complete psychological toolkit for advanced coaching, in fact, it offers far more than a toolkit. It will help you along your coaching journey by offering a wide array of research and perspectives. At the Institute of Coaching at Harvard Medical School we see that the greatest challenge facing coaches today is to bridge good theory and research to best practices. The Association for Coaching and Jonathan Passmore achieve this difficult challenge with ease and grace. As you absorb the information presented here, the theory, its application and case examples will help you pull knowledge and wisdom from your mind to your heart and gut."
Carol Kauffman , Founder and Executive Director, Institute of Coaching
