Elias’s osteosarcoma journey began at 10 years old with pain in his right shoulder and arm. In January 2022, our world changed forever when he was diagnosed with high-grade osteosarcoma.
His cancer was resistant to chemotherapy, and in May 2022, at just 11 years old, Elias’s right arm was amputated in an effort to save his life.
What happened next still amazes us.
Elias worked incredibly hard to figure out how to do the things he had always done, now with one arm. It wasn’t easy, but he kept finding his own way. He proudly gave himself the name One Arm Pro and created his own YouTube channel, sharing his personality, creativity, and gaming. He even dreamed of creating his own bionic arm someday.
The cancer returned in his lung in 2023 and was surgically removed, giving Elias nearly a year to simply be a kid again. In July 2024, we learned it had returned and spread. Elias went home to Jesus on September 23, 2025, at 14 years old.
But cancer was only one part of Elias’s story.
Elias was funny, imaginative, tenderhearted, and deeply loving. He loved Jesus and his family fiercely. His brother Lazarus meant the world to him, and his sweet corgi Solo was quite literally his spirit animal.
He loved stuffed animals, building Legos, drawing, all things Pokemon, gaming, cooking, creating, and giving to others. He was our chef, and he loved making food to share with the people he loved. He made people laugh and had a beautiful way of bringing people together.
After losing his arm, Elias continued to build, draw, cook, play, and create, even when it was really hard. His determination amazed us. There were so many beautiful parts of him and so many dreams for who he wanted to become.
Today, we carry his giving heart forward through Think Like Elias, giving back to children and families facing childhood cancer. To Think Like Elias means to love people well, include others, give generously, and bring joy wherever you can.
Elias was also a proud MIB Agents Warrior Mail recipient. Through the Elias Garcia Family Fund, we now have the privilege of carrying that love forward by helping fund the osteosarcoma research children like Elias so desperately deserve.
We will keep saying his name, sharing his story, giving in his honor, and fighting for better treatments for the children who come after him.
