About PRI

The Postural Restoration Institute® (PRI) was established in 2000 to explore and explain the science of postural adaptations, asymmetrical patterns and the influence of polyarticular chains of muscles. Our mission is based on the development of an innovative treatment that addresses the primary contributions of postural kinematic movement dysfunction.


The Postural Restoration Institute® was established in 2000, and the science of Postural Restoration® continues to grow. PRI now has 243 Postural Restoration Certified™ (PRC) professionals, 68 Postural Restoration Trained™ (PRT) professionals, and over 100 Postural Restoration Centers™. Courses are hosted each year in the United States and Internationally. This includes PRI’s three primary courses, four secondary courses, and five tertiary courses. 

In addition to live course offerings, the three primary courses are available as online home study courses. PRI has produced three editions of a CD comprised of Non-Manual Techniques and a first edition Manual Techniques DVD. The Non-Manual Techniques programs, and the Manual Techniques video are both available to be purchased as a Digital Download as well. 

We have also produced PRI Non-Manual Techniques Video Programs. Our website is the primary source for information regarding courses, location of nationwide PRI health professionals, educational materials, daily news, dialogue and references.

PRI Guidance

After 16 years of hospital and outpatient-based care, I knew I had reached a significant point in my career when a majority of my patients reached optimal functional outcomes through the incorporation of left acetabular femoral internal rotation, the isolated facilitation of left femoral adductors and left thoracic abductors, the establishment of a left zone of apposition, and the enhancement of right brachial expansion.

It was often difficult to convince physicians and physical therapists to reposition a pelvis and a femur before stretching out an iliotibial band or performing an iliotibial band release surgically. That’s why I established a private practice and the Postural Restoration Institute®. 

My clinical experiences, outcomes, and my former and present patients continue to guide PRI educational endeavors. The gratification on a patient’s face reinforces the development, formation and application of each PRI manual or non-manual technique.


To Lifelong Learning

Reading journal articles, books and research has increased my appetite for information on anatomical and physiologic imbalance. My mind is a reflection of my commitment to test knowledge through experience, persistence and willingness to learn from mistakes. The Anterior Interior Chain of our bodies is a reflection of reasoning, leading to a PRI experience. I will continue to connect links by continuing to commence with PRI experience in different areas like aquatics, ophthalmology or orthodontics.

To Service

As a former dental student who dropped out of the dental tract to pursue reasoning behind teeth being chewed up on one side, I’ve always had a mindset for non-linear linkage. As Leonardo da Vinci recognized and appreciated “interconnectedness of all things and phenomena,” so do I. Long before the Guide to American Physical Therapist Practice was written, I embraced ambiguity, paradox and uncertainty.
