Sarah Peterman, MSW, LCSW


Philosophy of Care: 

Engaging and down to earth, Sarah Peterman approaches clients with compassion, insight, and a strong dose of humor. She easily establishes rapport with clients of all ages, including children as young as 5 years old, creating a calm and supportive environment for successful treatment. Clients develop an understanding of the barriers that are holding them back, as Sarah teaches them to challenge anxious thinking and modify behaviors. She gently pushes clients to engage in situations that they had been avoiding, increasing tolerance for anxiety and helping them to recognize triggers and approach circumstances in a new, more helpful way. As an experienced clinician, Sarah is creative in finding ways around each person’s unique barriers, and personalizes strategies that motivate change. She recognizes the importance of involving parents when working with children, and provides guidance on boundaries, limits, and communication that facilitates improvement and progress in their children. Sarah consistently helps her clients overcome anxiety and achieve positive outcomes, teaching new skills and strategies that increase self-confidence and result in an improved quality of life.

She specializes in the use of Cognitive Behavior Therapy (CBT), Exposure and Response Prevention (ERP), Dialectical Behavioral Therapy (DBT), and mindfulness, including relaxation practices. She relates well to children and adults, tailoring age-appropriate treatment for children and adolescents that can include play, music, and rapport-building.

An animal lover, Sarah enjoys spending time with her dog and cat, and volunteers at a therapeutic riding program. To relax, you’ll often find her reading and listening to music.

Sarah is an experienced licensed clinical social worker, having worked in a variety of residential and outpatient settings as well as in private practice.
