Sierra Klotz Spinney, LICSW

Sierra Spinney is a licensed clinical social worker and a clinician at the Complex Trauma Treatment Center Boston. She specializes in the treatment of adolescents and adults impacted by developmental and relational trauma, resulting in PTSD, Complex PTSD, dissociative disorders, and attachment disorders. She uses relational and evidence-based approaches to help clients begin to understand the impact of trauma while feeling supported and cared for.

Sierra graduated from Smith College School for Social Work and went on to complete a post-masters fellowship on the Victims of Violence Team at Cambridge Health Alliance. Here, she trained with experts in the field using the Stage Model of trauma recovery, Internal Family Systems (IFS) and Accelerated Experiential Dynamic Psychotherapy (AEDP). She has also practiced clinical work with adolescents in a school setting in Northern California and with adults at Positive Impact Health Centers, an HIV clinic in Atlanta, GA.

Sierra is particularly interested in the intersection of complex trauma and identity development, as well as the impact of political trauma and immigration. She approaches clinical work with cultural humility, knowing every person experiences the world differently based on what they have had exposure to.

Sierra also has experience treating other mental health disorders such as major depressive disorder (MDD), generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), gender dysphoria, adjustment disorder, and substance use disorders. She uses evidenced based approaches to treat these disorders such as Mindfulness Based Stress Reduction (MBSR) and relational psychotherapy.
