About LARSO

The Los Alamos Retired and Senior Organization (LARSO) is a nonprofit 501(c)(3) social impact organization that promotes collective wellbeing and healthy aging through social engagement, physical well-being, civic involvement, creativity, and lifelong learning. Since opening in 1998, the Betty Ehart and White Rock Senior Activity Centers have offered a safe place that provides numerous services, including day out/daycare, transportation, community meals, home-delivered meals, activities, and entertainment. We believe that when an older adult is healthy, our whole community thrives.
