My name is David Benet and I am the Volunteer Coordinator for Mobility Matters.  This event calendar takes time and effort.  If this page helps you out then please help me out by sending volunteers to me.  I am looking for volunteers drivers that can help seniors and veterans get to medical appointments or go grocery shopping. One ride a month takes 3 hours.  If you know anyone that might want to become a volunteer please have them contact me at (925) 284-2215 or [email protected].
