About HD GEM


The mission for the Huntington's Disease Global Ecosystem Map (HD GEM) is to further engage with the "silent" 70% of the HD community by helping those impacted by Huntington's disease(HD) find the resources they need to better assist them on their HD journey. This not for profit project was started and created by Casey Herrington with the guidance of an advisory team made up of leaders within the HD community.

Project Creator

Casey Herrington

Casey has been working for the Huntington's Disease Global Ecosystem Map full-time since receiving grant funding in 2018. His involvement in the HD community was sadly inspired by personal loss; his mother passed away from Huntington's disease in 2013 when she was just 46 years old. He and his three sisters remain at risk of developing the disease. With an entrepreneurial passion, Casey is striving to aid in the fight of creating a world without Huntington's disease.
