David Vail CEO, LCSW

David specializes in treating adolescents, young adults, and adults with substance misuse and mental health issues. David strongly believes in the capacity of individuals to heal and maintain lasting wellness. In long-term recovery himself, David uses a non-judgmental, compassion-based approach to treat addiction and promote mental wellness. Trauma informed care is a primary factor in David’s work with individuals and families to help facilitate positive change in their lives. By addressing causality and early childhood trauma, David has successfully helped many individuals taper off antidepressants, anti-anxiety medications, and chronic pain medications through effective non-pharmaceutical avenues of treatment to address the root causes of mental illness and behavioral problems. He uses cognitive behavioral therapy, motivational interviewing, and mindfulness-based stress reduction methods to help people get well and stay well.
