Before he was born, Jack was diagnosed with bilateral fibular hemimelia, a rare limb difference that affects the development of the fibula bone. His family turned to Nemours Children’s Hospital, Delaware, where they found expert guidance, compassionate support, and hope for the future.

At age 1, Jack underwent bilateral amputation and began his lifelong journey with prosthetic care through Nemours. Today, at 19, he is thriving as a sophomore at Penn State University, where he studies mechanical engineering and competes on both the club and adaptive track teams. In July 2026, Jack competed at the USATF Para Nationals in New York, winning gold in the men's 400-meter race and silver in the men's 100-meter race. He hopes to one day represent Team USA in the Paralympic Games.

Jack credits his success to the support of his family and the care team at Nemours, who helped him build confidence, independence, and the belief that anything is possible. As a Patient Ambassador, he hopes to inspire other patients and families by showing what can be achieved through determination, resilience, and exceptional care.

Jack's advice to other families: “Do your research. Ask to speak to other patients and families. Advocate for your child."

Vacation time usually means something fun and relaxing. But for Malcolm Wills and his family, a 2023 trip to New England was cut short by an unexpected medical emergency that required brain surgery and a lengthy stay in intensive care. 

Once he was stable, Malcolm transferred to Nemours Children’s Hospital, Delaware to continue his recovery. Malcolm needed to relearn everything from sitting up to walking to jumping.  

Over the following months, both inpatient and through outpatient rehabilitation, he worked closely with physical, occupational and speech therapists, while also staying on track with daily lessons in our hospital school program. 

Today, Malcolm is a healthy, active 11-year-old who enjoys playing sports with his friends. His progress reflects his hard work, his family’s involvement, and the coordinated medical care he received from his team at Nemours Children’s. 

Malcolm and his family are grateful for the care they received, and for having that support close to home when they needed it most.
