William McKenzie, LPC, is dedicated to helping individuals and families navigate life’s challenges with authenticity, resilience, and purpose. Practicing at LifeStance Health in Missouri, William offers a compassionate, collaborative space for clients of all ages—from children and adolescents to adults and midlife individuals. He specializes in providing tailored care for those managing anxiety, depression, ADHD, and life transitions, equipping clients with practical tools and insights to reclaim control of their emotional well-being.

A central focus of William’s work is supporting individuals who identify as neurodivergent, including those with ADHD, Autism Spectrum Disorders, and developmental disabilities. He is passionate about fostering environments where clients feel safe, understood, and empowered to thrive on their terms. Through his integrative, strengths-based approach, William draws from evidence-based interventions such as Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Acceptance and Commitment Therapy (ACT). He also utilizes Christian counseling and mindfulness techniques when appropriate, offering care that honors the diverse identities and values of his clients.

In addition to his expertise in mood and behavioral disorders, William has a strong clinical interest in addressing complex issues such as PTSD, grief, school avoidance, sleep difficulties, and relationship challenges. He is experienced in working with LGBTQ+ individuals, military veterans, and those navigating medical or somatic health conditions, delivering personalized, empathetic care designed to meet clients where they are in their mental health journey.

Outside of his professional practice, William nurtures his creativity and well-being through music, writing, and reading. An avid guitarist and songwriter, he values the therapeutic role of self-expression and incorporates elements of expressive and play-based therapies into his work. His love for sports and outdoor activities reflects his commitment to balance, resilience, and holistic wellness.
