Our Team

Alex Volpe

Program Manager

Alex has been working with underserved youth and families for over 15 years.  Upon completing her Masters in Social Work at the University of Chicago in 2005, Alex worked as a therapist at Mercy Home for Boys and Girls, a residential treatment facility in Chicago.  After moving to the East Bay with her family in 2008, Alex began working at Bay Area Youth Center/Sunny Hills Services (now “Side by Side”), a nonprofit serving foster and probation youth.  Alex led Bay Area Youth Center as the Executive Director from 2013-2017.  Under Alex’s leadership, Bay Area Youth Center significantly expanded mental health and housing services to youth in Alameda County, and earned a reputation as an agency who would provide shelter and services to the highest need youth who were often terminated from other services due to their acute mental health symptoms.  Alex is committed to the principles of trauma-informed care and providing culturally relevant services to young people and their families.  

Following her tenure at Bay Area Youth Center, Alex has held a number of contract and interim positions, including serving as the interim chief operating officer at Unity Care Group, as well as the Executive Director at the Ann Martin Center.  Prior to becoming a Licensed Clinical Social Worker, Alex received her JD from the University of Texas in Austin and worked as a corporate and securities attorney in San Francisco and Austin.  She currently lives in Oakland with her family.
