About Us

SPIRAL Foundation

The Sensory Processing Institute of Research and Learning – or SPIRAL – Foundation is a nonprofit organization founded in 2001 by Dr. Jane Koomar and Anne Trecker, and our for-profit sister organization OTA the Koomar Center, then known as Occupational Therapy Associates – Watertown, P.C. Our mission, is to conduct research and provide professional and community education about sensory integration and sensory processing.

The Spiral Foundation Sensory Processing Research Center and Laboratory promotes multi-disciplinary partnerships by forging relationships with nationally known researchers and leaders in the field of sensory processing and related disciplines. To ensure the ethical treatment of persons enrolled in studies all research is approved by the Spiral Foundation Institutional Review Board. Research findings are disseminated via the Spiral Foundation website, conference presentations, and peer-reviewed publications.



The Spiral Foundation Community and Professional Education program strives to make information about sensory processing and sensory integration intervention as accessible as possible by providing free resources for individuals who have, or suspect they have, sensory processing dysfunctions and their families, and by offering professional continuing education opportunities in a variety of formats at competitive prices. Through collaboration with leading experts in the field of sensory integration and related disciplines, the Spiral Foundation assures that the quality of this information is among the very best.

Our Founder

Jane A. Koomar, PhD, OTR/L, FAOTA was the owner and co-founder of OTA-Watertown and the President of the Board of the Spiral Foundation. She completed her doctoral studies in developmental psychology at Boston University where she was formerly an assistant professor in occupational therapy. She taught at Tufts University, Boston School of Occupational Therapy in a one year Professor of Practice position. In 1984, she studied with Dr. Jean Ayres, who developed the theory of sensory integration.

Dr. Koomar served as the chairperson of the Sensory Integration Special Interest Section and was a member of the Mental Health Special Interest Section, both part of the American Occupational Therapy Association.

Jane seemed to get along with everyone, often navigating the many politics involved in sensory integration within and without OT with ease, a true feat among  high-powered and opinionated professionals.  Jane’s passion for her work was genuine filled with deep emotion.  Her interests were often in those that were underserved and misunderstood by the world at large. She cared deeply about her family, her friends, her community, her profession, and the well-being of children and families. She made time to listen and to be present for them.

Jane passed away from breast cancer on February 23, 2013 at the age of 59.

Jane’s Philosophy…

There is nothing you can nor have a right to do. For those who are unwilling to explore, you cannot coerce, you cannot nudge forward, you cannot threaten, you can only offer.

And if someone says a tentative yes, then move gently and sweetly towards them.  Offer to abide with them on their journey.

Do whatever it is in the movement that you are requesting them to do and be ready to have them withdraw or fly forward at any given moment.
