Sadie Williams

For Sadie Williams, 2025 began not with the typical resolutions of a third-grader, but with a challenge that would redefine her world. On January 1, Sadie was brought to the emergency room with intense knee pain. By January 3, her life took a sharp turn when she was diagnosed with osteosarcoma of her right femur. Within hours she was placed in a cast stretching from her toes to her hip. Almost overnight, the girl who defined herself through motion—skateboarding, softball, swimming, and performing endless cartwheels—was restricted to using only her left leg.

The seven months that followed were a testament to Sadie’s amazing spirit. Her battle was grueling: she endured 22 rounds of chemotherapy and spent 127 days within the walls of the hospital. She underwent two major surgeries, including a complex 10-hour operation to remove the cancerous bone and replace it with a donor bone. Through the physical toll of treatment, Sadie never stopped fighting. While she experienced natural moments of fear and sadness, she never closed herself off. Instead, she became her own best advocate, developing a profound connection with her body and knowing exactly when to push forward or when to ask for a moment of rest.

Sadie’s journey was supported by a dedicated community. At Stony Brook Hospital, the Pediatric Oncology Unit became a second home where child life specialists, art therapists, and social workers helped her navigate the emotional weight of her diagnosis. Education remained a bridge to her “normal” life; her third-grade teacher, Ms. Eten, provided home-schooling between hospital stays, ensuring Sadie didn’t fall behind. There were moments of pure joy, like Zooming into her classroom to see her friends or receiving a special visit from Ms. Wallace for a morale-boosting ukulele jam session.

On September 28, Sadie reached a milestone she had worked toward all year: her last treatment. A few days later, a PET scan confirmed the news everyone had prayed for—she was cancer-free. The relief was overwhelming, and Sadie’s signature spark, which had been dimmed by the rigors of chemo, returned with a brilliant glow.

On November 17, Sadie officially returned to school. Though she still uses crutches as her body continues to heal, she is navigating the hallways with the unwavering support of her staff and peers. She has thrown herself into new passions, learning to play drums and eagerly preparing for chorus. Sadie has always been a beam of light—a kind, compassionate soul who strives to make everyone feel included. As she heals both mentally and physically, she is growing stronger every day. Sadie Williams is more than a survivor; she is a positive force who has learned the power of standing up for herself, and there is no doubt she will spend her life doing the same for others.
