“I want people to do more of what they love to do,” John Lieberman said when speaking about his new position as Executive Director of The New York Center for Living. “I am committed to helping NYCFL continue to thrive, to grow and to succeed as an adolescent and young adult intensive outpatient treatment service. The New York Center for Living is a clinically driven program that provides comprehensive treatment to individuals and families in a 12-Step, abstinence-based model. The foundation of my work and expertise in the treatment industry mirrors that of NYCFL and I am proud to represent the program and further its growth as it continues to impact the lives of many people.”

Currently, there are twenty-eight beds and five different programs, including the first private sober recovery high school, and the first licensed extended care treatment for adolescents in the state of California.”

John holds a Master’s degree in Industrial and Organizational Psychology and chooses to focus his skills specifically on improving company culture by maximizing staff and individual assets within an organization. John is committed to helping clients and their families heal and recover from the damages of addiction and co-occurring disorders and recognizes that NYCFL staff can create this kind of stability needed to achieve that goal. John added, “ I love to facilitate the magic that happens when many individuals, coming from different backgrounds and cultures, all work together for the good of the clients and their families.” “I am looking forward to working with Elizabeth Kabler, the Founder and Chairman of the Board of Trustees; she works tirelessly to promote NYCFL. I also am eager to work with the Board of Trustees, to spend time with the staff, and to continue to learn more about the Center, its clients and their families,” he added. One of the goals he has for NYCFL is to have it “become a voice for teaching, training and leadership in New York for professionals, families and educators who are working with those struggling with substance abuse and addiction.”

Val invites clients to safely and gently explore unconscious content, externalizing felt experience to promote recovery and well-being.
