Dave MacQuarrie is a physician-psychotherapist with 25 years of experience. For the past 15 years, his work has focused on anger management. The Blowing Out! process originates from his own personal journey, starting with early childhood experiences that led him to become an independent thinker. He began his adult career wanting to be an astrophysicist and subsequently acquired five university degrees in various disciplines. Thus he started out studying the outer universe, not realizing that his journey would take him to explore our inner universe. In this journey, he has come to value wisdom over knowledge. His strong sense of values and creativity has allowed him to develop his unique practice as his personal way of contributing to society.
