Chordoma Foundation


Our talented staff works with dedication and urgency to advance the Foundation’s mission and make a difference in the lives of chordoma patients.

Josh Sommer

Co-Founder and Executive Director

Josh was diagnosed with a skull-base chordoma in 2006. Unwilling to accept the limited treatment options available to chordoma patients, he joined the lab of Dr. Michael Kelley at Duke University, where he spent the next two years studying chordoma. There he experienced the very practical challenges faced by virtually all would-be chordoma researchers – insufficient funding; scarcity of tissue, cell lines and animal models needed for experiments; and isolation from others studying the disease. To solve these problems and proactively advance the search for a cure, Josh co-founded the Chordoma Foundation in 2007. Under his leadership, the Foundation has united and expanded the chordoma research community and vastly accelerated the pace of chordoma research. As Executive Director, Josh works with the Foundation’s research partners, advisors, and supporters to design, execute, and fund research initiatives focused on developing new treatments for chordoma.
