Miles Hartz’s Story
With heavy hearts we regret to inform you that Miles Hartz passed away from osteosarcoma at the age of 17 on Sunday, June 25, 2023.
Miles and his family were deeply devoted to being advocates for everyone suffering from this rare and devastating cancer. Please consider a donation today in memory of Miles.
Miles was a lover of extreme sports. His favorite was go-kart racing. Miles endured four grueling years of chemotherapy and several surgeries to battle his cancer. He faced his osteosarcoma diagnosis with courage, patience, and dignity.
We refuse to accept a world where treatment for osteosarcoma is not effective for all patients. A gift to the Osteosarcoma Institute (OSI) supports the most promising clinical trials and science to fight osteosarcoma and give kids with this devastating disease hope.
The OSI is grateful for the many ways that the Hartz family has supported us. In memory of Miles, we will keep the fight going.

“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

What We Do
Our Strategy
Globally estimated, there are over 26,000 new cases of osteosarcoma diagnosed each year, with 1,000 being diagnosed in the US, but treatment options haven’t advanced in 40 years. To find a cure for osteosarcoma, we have to collaborate, innovate, and translate around the most promising science.
Our Mission
The Osteosarcoma Institute’s mission is to dramatically increase treatment options and survival rates in osteosarcoma patients through identifying and funding the most promising and breakthrough osteosarcoma clinical trials and science.
Our Impact
Removing obstacles, funding advancements, accelerating progress, and raising awareness. The Osteosarcoma Institute funds breakthrough clinical trials and science to identify new treatments and, ultimately, a cure for osteosarcoma.
