Marjorie Kasten is one of the most knowledgeable physical therapists using FDM in practice. Having worked directly with Dr. Typaldos for 9 years, she represents our strongest link to the founder and originator of the FDM. Working together in consultation, often side by side, assisting not only in patient care, but in developing effective Physical Therapy applications, video-taping patient treatments, editing the early and final editions of the FDM textbook, and assisting with FDM seminars, her background and institutional knowledge of the development of the FDM over time gives her unique authority and ability in all things FDM. She continues to serve as the Executive Director of the American FDM Association, maintains an active Physical Therapy FDM practice, and is an accomplished FDM instructor. Her expertise in the area of Inversion Therapy for stubborn and resistant folding distortions distinguishes her contributions to the FDM, and is invaluable to the future of the FDM.
