Charity Partner
Rocky Cares
Who we are:
Rocky Cares was founded by Rocky's family and friends who were inspired by her courage, resilience, and positivity in the face of a rare and aggressive form of bone cancer. Rocky was diagnosed with Ewing sarcoma at the age of 13 and she battled for five years undergoing countless rounds of chemotherapy and radiation, surgeries, and experimental treatments. Despite the challenges and hardships, Rocky refused to let cancer define her narrative. She excelled academically, athletically, and gave back to her community. She was the best friend to many and touched the lives of a community.
Our Mission:
Rocky Cares is a nonprofit organization created in memory of Rocky Elardo, a bright, beautiful, and brave young woman who lost her battle to Ewing sarcoma in February 2024. Rocky Cares aims to honor Rocky's life and legacy by raising awareness and funding to support Ewing sarcoma research for a cure; providing an annual scholarship to senior(s) at Heritage High School that embody Rocky's qualities of intelligence, athleticism, and kindness; and spreading Rocky's sunshine throughout the community.
