Where GIS meets ALS

We’re bringing
GIS science to the
ALS battle
GeoALS is a nonprofit founded to tackle ALS by applying GIS —specifically location analytics and data visualizations—to ALS by:
Supporting researchers who study environmental exposures and patient place history
Connecting underserved ALS communities to resources; increasing the number of ALS registry registrants
Improving access to clinic care and ALS expertise; shortening time-to-diagnosis
-
The seed idea for GeoALS came to founder Pat Dolan just after he was diagnosed with ALS in 2016. Up until 2016, Pat had spent 25 years working with GIS in the utility industry—20 of those years with Esri.
Since 2016, Pat has taken up offers of help from his Esri friends, and quickly a volunteer group formalized called The Mappers. Over the years, The Mappers, led by Pat, have worked with partner orgs to create maps and apps that support care access, environmental risk factor research, and education. In order to sustain this work, Pat founded the nonprofit GeoALS in October 2024.
GeoALS has nearly the same group of Mappers supporting it today. Esri continues to donate its GIS location platform to support this important work.
