Welcome to ACE for WS
The Armellino Center of Excellence for Williams Syndrome was established in 2022 after a generous gift from Michael R. Armellino, W’61. With a vision to pioneer research and strategically bridge the gap between pediatric and adult care for individuals with Williams syndrome, our medical and behavioral health teams provide comprehensive and collaborative multidisciplinary services for individuals throughout the lifespan. We recognize every individual with WS is unique and provide individualized care plans and support to help our patients and their caregivers obtain the services they require as they transition to new stages of their lives.
What is Williams syndrome?
Williams syndrome (WS) is a rare genetic disorder that occurs equally across all populations. Approximately 1 in every 7,500 individuals are born with WS. Williams syndrome is a complex disorder with highly variable presentations that involve unique medical, behavioral, and developmental features that require specialized care.
