I am a Licensed Mental Health Counselor (LMHC) and Certified EMDR Therapist, providing trauma-informed online therapy for adults in Massachusetts and Connecticut.

My work focuses on helping clients heal from complex trauma, PTSD, dissociation, anxiety, and mood disorders through evidence-based and compassionate care.

I am certified in Eye Movement Desensitization and Reprocessing (EMDR) and trained in Internal Family Systems (IFS) therapy—two powerful trauma recovery modalities that help clients process painful experiences, restore emotional balance, and reconnect with their inner sense of calm and self-leadership.

My approach is grounded in safety, collaboration, and curiosity. I believe that healing happens at your own pace, and that therapy provides a space to reconnect with the parts of yourself that are ready to heal.

Before founding my private practice, I spent over a decade working in community and outpatient mental health, helping individuals navigate trauma, mood disorders, and life transitions. Those experiences taught me that lasting change begins when people feel truly seen, supported, and empowered to lead their own healing.

About Mateusz Marcinowski, LMHC

Certified EMDR Therapist | Trained in Internal Family Systems (IFS)

Therapeutic Philosophy

My therapeutic philosophy is rooted in the belief that every person carries an innate capacity for healing and self-leadership. I strive to create a safe, collaborative space where you can explore your experiences without judgment and begin to reconnect with the parts of yourself that have long carried pain, fear, or shame.

In my work, I approach each person with deep respect and curiosity—recognizing that no two healing journeys are the same. Whether we’re working through trauma, anxiety, or patterns of disconnection, I draw from EMDR and Internal Family Systems (IFS) to help you process the past, build emotional balance, and cultivate inner compassion.

As an affirming ally to the LGBTQIA+ community, I welcome clients of all gender identities, sexual orientations, and life experiences. My goal is to provide a space where you can be fully seen and supported as you move toward authenticity, empowerment, and healing.

Healing begins when we feel safe enough to listen to the parts of ourselves that have long been unheard
