Karyn Shanks MD is a physician-healer-teacher-author who lives and practices in Iowa City. Her work is inspired by the science of Directable Human Potential—epigenetics, neuroplasticity, core Functional Medicine systems biology, and transformational psychology—and the wisdom gleaned from the healing journeys of thousands of clients over her thirty-year career. She approaches all of her work through the Unbroken philosophy and framework—that we all have vast untapped genetic, biological, psychological, and spiritual potential.
