Subregional Mobility Managers

A strategy outlined in the MAG Human Services Coordination Transportation Plan is the utilization of sub-regional mobility managers to enhance and promote regional mobility coordination planning efforts in the region. This has included identifying sub-regional mobility managers as community liaisons for the East Valley, West Valley, Central Area, and the South-Central Valley of the MAG region. The sub-regional mobility managers participate in designated workgroups, provide feedback on trainings, and provide support for regional coordination strategies outlined in the MAG Human Services Coordination Transportation Plan.

Billy holds a Master of Administration with Leadership Emphasis through Northern AZ University and has seen a great amount of diversity through management of a wide range of services in multiple states.

Vehicle Sharing

Vehicle sharing is a unique program that involves vehicles acquired through a federal grant program. Agencies share an accessible vehicle that enables people with disabilities to get out of their homes. Many social services say that a major challenge they face is a lack of transportation as public transit options may not be the best fit.
