Growth, healing, and professional development rooted in compassionate care.

Psychotherapy for individuals and training, consultation, and supervision for clinicians — grounded in trauma-informed, evidence-based practice by Marissa Holsten, LCSW.

At Evolve Therapy & Consulting, meaningful change unfolds gradually through reflection, resilience, and supportive connection.

Hi, I’m Marissa.

With nearly two decades of experience, I provide a safe, nonjudgmental space where adults can explore difficult emotions, heal from trauma, and move toward a more fulfilling life.

I also provide trainings, clinical consultation, and supervision for clinicians seeking to deepen their skills and provide thoughtful, evidence-informed care.

If you are here, you are already taking a brave step toward change.

My Services

Individual Therapy

My work is rooted in trauma-informed therapy, with an understanding that trauma can be both visible and unseen. It influences emotional health, behavior patterns, relationships, and the nervous system in nuanced ways. I approach healing with empathy and patience, honoring each person’s readiness and resilience. Together, we create a safe path toward stability, clarity, and empowerment. I am trained in EMDR and CPT.

Training, Consultation, & Clinical Supervision

I offer trainings, consultation, and clinical supervision for mental health professionals and organizations seeking to strengthen trauma-informed and evidence-based care. My work focuses on translating clinical knowledge into practical strategies that support effective, ethical, and sustainable practice.

Topics often include trauma-informed care, complex case consultation, clinician burnout prevention, and evidence-based therapeutic approaches.

Helping you Heal, Grow, and Evolve

Healing rarely happens in a single moment. It is a gradual process of change that unfolds through safety, insight, and support.

At Evolve Therapy & Consulting, this philosophy guides both psychotherapy for individuals and training, consultation, and supervision for mental health professionals.

The name Evolve reflects a core belief: people are not broken - they are continually growing, adapting, and becoming.

Like a tree rooted in lived experience, each person carries both wounds and strengths. Even in seasons of pain, stillness, or uncertainty, growth may be unfolding beneath the surface.

This work is grounded in trauma-informed, evidence-based approaches that support both personal healing and thoughtful clinical practice.

Growth takes time. Healing takes courage. Change happens one step at a time.
