William Trump’s life has become a source of inspiration for his father, Fred C. Trump III, who has turned personal experience into a platform for disability awareness. Fred, a nephew of former President Donald Trump, chronicles their family story in his memoir All in the Family, exploring the bonds and challenges that have shaped their lives.

Born with a rare KCNQ2 genetic mutation, William experienced severe seizures and developmental disabilities from an early age. His childhood was marked by frequent medical crises, and his family spent 15 years searching for answers before finally receiving a diagnosis.

Despite these challenges, William found joy in everyday pleasures, from swimming and peanut butter sandwiches to listening to reggae music. Today, as a young adult, he uses a wheelchair and is nonverbal. He recently transitioned to a specialized group home in Connecticut, providing him with consistent care while remaining close to family.

Fred has leveraged William’s journey to advocate for people with profound disabilities, emphasizing the importance of respect, meaningful engagement, and access to proper care. He promotes better caregiver training, expanded housing options, and early medical intervention, sharing insights at events including the American Association of People with Disabilities.

With support from his family, William receives private therapies such as music and aquatic programs. Fred hopes to make such opportunities accessible to all families, regardless of income. Alongside his wife Lisa, Fred continues to champion the needs of families navigating developmental disabilities, using William’s story to drive awareness, foster understanding, and encourage systemic change.
