Strength Lives On.
Sak Strong Foundation was created in honor of Christopher “Sak” Sakelakos and his courageous fight against Osteosarcoma. Chris was a husband, father, son, brother teacher, coach, and friend whose strength, kindness, and love for his family left a lasting impact on everyone around him.
Our mission is to raise awareness, support families facing Osteosarcoma, and help fund the research needed to improve early detection, treatment, and ultimately find a cure. Through community, compassion, and action, we hope to ensure that no one fights alone.

Every dollar moves research forward and supports families in treatment.
Our Mission
The legacy and memory of Chris Sakelakos’ courageous battle against Osteosarcoma inspired the Sak Strong Foundation which is dedicated to raising awareness and advancing medical research for Osteosarcoma (bone cancer).
Chris was diagnosed with Osteosarcoma in May 2024, and valiantly and bravely endured many surgeries, various combinations of chemotherapy and many other medical interventions; the cancer unfortunately metastasized and traveled to his lungs, ending his time on earth on September 16, 2025.
Awareness + Research
We raise funds to support medical advancements in Osteosarcoma and sarcoma research, pushing toward better treatments and better outcomes.
Scholarship Fund
Each May, we award a scholarship at Lynnfield High School in Chris’s honor, supporting students who demonstrate strength, compassion, and dedication to their community.
