Humane Borders founder Rev. Robin Hoover left the group dedicated to helping migrants heading north from southern Arizona more than 18 months ago.
New executive director Juanita Molina is a 20-year veteran of social-activism organizations who recently moved back to Arizona from Northern California. She considers herself the point person for the organization but said she won't be the only one handling media interviews or making appearances on behalf of the group.
The organization was founded in 2000 and has about 45 water drums placed in the desert in an effort to prevent deaths.
Hoover declined to discuss his reasons for leaving to the Arizona Daily Star.
