Bill Harvey has been a Certified Rolfer since 1984, Certified Advanced Rolfer since 1990, Rolf Movement Practitioner since 1999, and Biodynamic Craniosacral practitioner since 1984. His interest in combining these three approaches while working with clients led to the develop-ment of his trainings in Biodynamic Structural Integration, which began in 2005.The problem of figuring out how to not run out of breath while distance running, and being around adults with emphysema, captured Harvey's interest in breathing at an early stage. A large part of the attraction that Rolfing held for him lay in that discipline's ability to alter the texture and pliability of the intercostal muscles of the ribcage so that there could be more room for the lungs to expand, and more ease throughout the thorax to allow the lungs to de-flate more fully. Since the early 80s his professional interest in breathing has followed two paths of inquiry: 1) how to free up tissue within the body, by working with connective tissue; by increasing the mo-tility of the individual lobes of the lungs through visceral manipulation; how to tease out limit-ing habitual holding patterns through movement therapy; and how to titrate out emotional and kinetic charge through Biodynamic Craniosacral Therapy; and 2) to discover whether or not there are any inherent feedback loops within the body that can be called upon to support our activities.During his more than three decade full-time career in manual therapies, Harvey has also pur-sued a variety of interests that deepened his work and instruction of Structural Integration. These interests have centered on questions of how life works. What is our proper place in Na-ture? What is the relationship between the wiring of our nervous systems, established through our attachment patterns and our physical structure and behavior? What is the relationship be-tween our belief systems and structure? What is the relationship between ancestral patterns and structure and behavior? Most importantly, what can work with these realities?Our breathing activates the answers to these questions, leading us on a path to embodiment that clarifies and contextualizes our inner experiences within the natural world.
