About us
Why We Exist

Our Mission
The Oxalosis & Hyperoxaluria Foundation (OHF) is dedicated to finding treatments and a cure for all forms of hyperoxaluria.

Our Impact
We support thousands of healthcare professionals, patients, and their families, and we aim to share our knowledge so that everyone has accurate information about the advances in this disease.
By supporting research and spreading awareness about the disease among patients, medical professionals, government officials, the general public, and industry, we aspire to create brighter tomorrows for those impacted by primary hyperoxaluria, oxalosis, and related hyperoxaluria kidney stone conditions.

How We Do It
We are a donor-funded, 501(c)(3) nonprofit, spending 90% of every dollar raised on research and programs for our community.
Executive Leadership
Our people are determined and innovative, working around the clock to end hyperoxaluria. The contributions from these exceptional individuals keep the Oxalosis & Hyperoxaluria Foundation moving forward.
