Introducing...
An Upcoming New Framework for PWS Care
The Prader-Willi Optimization System (PWOS)
Caregivers of individuals with Prader-Willi Syndrome (PWS) face a wide range of daily challenges — from behavior management to food security to emotional regulation. Addressing these challenges requires more than intuition or trial-and-error. It requires structure.
The Prader-Willi Optimization System (PWOS) is a structured, experience-based framework developed to help caregivers navigate PWS care with greater clarity and consistency.
Created by Dr. Larry Genstil, Ph.D., based on more than 45 years of hands-on experience, PWOS organizes PWS care into six core pillars and 26 practical modules. This approach is grounded in clinical insight, educational programming, and real-world application across home, school, and residential settings.
The PWOS system is currently being adapted into accessible training formats for families, professionals, and caregivers. A full free course and digital community are coming soon.
