Miles Hartz’s Story
With heavy hearts, we share that Miles Hartz passed away from osteosarcoma at the age of 17 on Sunday, June 25, 2023.
Miles was a lover of extreme sports, and his favorite was go-kart racing. He brought energy, determination, and joy to everything he did.
Over four grueling years, Miles endured chemotherapy and several surgeries. He faced his diagnosis with courage, patience, and dignity, and he remained deeply devoted to advocating for others living with this rare and devastating cancer.
Miles’s life continues to inspire all of us who refuse to accept a world where osteosarcoma is not treatable for every patient.

A Message from the Hartz Family
From the bottom of our hearts, thank you. Thank you for honoring Miles and for standing with every child and family facing osteosarcoma. Your support is turning compassion into action and driving progress that patients urgently need.
Our mission is to cure osteosarcoma. The purpose behind that mission is deeply personal to us. It began with Miles, and it continues for every person who has faced osteosarcoma with courage and strength.
We have included a few signs we have used this year to honor Miles and other osteosarcoma patients, and to remember our shared purpose.
“Miles is my gem, and I would do anything for him. That’s why it is so important to us as a family to support the OSI as it pushes for better treatment options and a cure.”
David Hartz, Miles’s dad
