Katie Fosselius

A person-centered and strengths-based care approach defines the practice of Katie Fosselius, a Licensed Clinical Social Worker in Colorado who has been in clinical practice since 2001. Holding both a Master of Social Work and a Master of Theology, she utilizes a psychodynamic perspective with a significant focus on somatic integration. Her therapeutic style is deeply relational, aiming to establish a secure bond where meaningful healing can occur. Katie encourages her clients to become curious about the connection between their mind and body, viewing the individual as the expert of their own lived experience. In addition to traditional talk therapy, she incorporates somatic grounding tools such as breathwork to help patients connect with themselves. Based in Lakewood, Katie specializes in supporting adults aged 27 to 64 as they navigate a variety of mental health challenges. Her clinical expertise includes treating substance use issues, anxiety, depression, bipolar disorder, grief, and women's issues. She is particularly experienced in helping those who are re-evaluating problematic substance use or processing the effects of lifelong trauma and neglect. Her practice is informed by evidence-based modalities, including Acceptance and Commitment Therapy (ACT), Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and mindfulness. Outside of her professional work, she stays active through hiking and practicing restorative yoga, and she enjoys reading and spending time with her family.
