At Summit Therapy Center, we believe meaningful change begins when people feel safe enough to be understood as a whole person, not reduced to a diagnosis, behavior, or difficult season of life.

Our team works with children, adolescents, adults, and families in Billings, Montana. Many of the people we serve are navigating trauma, neurodivergence, anxiety, emotional dysregulation, family stress, developmental concerns, major life transitions, or complicated systems of care.

We are especially committed to work that requires patience, collaboration, and a deeper understanding of what may be happening underneath the surface. With children, that often means looking beyond behavior to development, attachment, communication, sensory needs, trauma, and relationships. With adults, it may mean helping make sense of long-standing patterns, complex trauma, emotional responses, and experiences that continue to affect daily life and relationships.

We believe strong clinical care should be both specialized and human. Our clinicians bring advanced training in trauma, child development, play therapy, neurodiversity, attachment, psychological assessment, and relational approaches, and recognize that no single method fits every person.

Families and caregivers are often important partners in the work, particularly when children are involved. We also collaborate with schools, medical providers, community agencies, and other professionals when that coordination supports the client’s well-being.

Above all, we want Summit Therapy Center to be a place where people can show up as they are. We value safety, dignity, curiosity, connection, and growth, and we believe serious therapeutic work can still make room for warmth, creativity, humor, and hope.

Our goal is simple: to help people better understand themselves and one another, strengthen the relationships that matter, and move forward with greater confidence and resilience.
