Meet our Seattle, WA & Denver, CO Trauma Therapy Team
We are a team of somatic and trauma-informed therapists who are passionate about helping clients reconnect with their bodies and come home to themselves.
We believe that a strong therapeutic container matters.
The Sona Collective Difference
Together, we will listen closely to your body’s cues for direction. In both our clinical practice and personal lives, we align with the Eastern philosophy that our bodies are our greatest source of wisdom. We bring a diverse and unique approach to trauma-focused therapy, combining academic and evidence-based principles with creativity, neuroscience, play, and movement.
Trained, in large part, by life experience, we are here to tell you that healing is possible. We specialize in EMDR and somatic psychotherapy, psilocybin therapy, ketamine therapy, and contemplative wisdom traditions for a holistic and integrated approach. We love to work directly with the emotional and somatic channels, inviting clients into a deeper presence of their embodied experience.
Our Philosophy
Who We AreBeliefs
We believe in the Buddhist concept of “Brilliant Sanity,” which says that within every human, regardless of what they have been through in life, there exists goodness and well-being that is everyone’s birthright. We believe that therapy is meant to uncover this brilliance; it’s a homecoming to what’s already whole.
How We WorkApproach
With decades of experience combined, our team offers a holistic and non-traditional approach to trauma therapy. While we believe there’s a time and place for talking, we lean heavily on a “bottom-up” therapeutic approach that uses body-centered and mindfulness-based trauma therapy techniques meant to work directly with the nervous system.
What We DoMethods
Our skilled therapists are trained in EMDR, mindfulness, psychedelic, and somatic therapies. We lean heavily on evidence-based modalities in our sessions, such as EMDR, somatic therapy, ketamine therapy, and mindfulness-based techniques, which are all backed by the latest research on the brain and nervous system.
Come home to yourself.

Our Services & Modalities
Trauma can show up as nearly any form of stress held in the nervous system, from autoimmune conditions and chronic pain to anxiety, depression, and substance abuse.
-
So often, therapy favors the mind and neglects the body and nervous system. As therapists specializing in somatic therapy, we aim to get you back in your body. We want you to feel relief, not just in our sessions, but in the following days and weeks.
The truth is that trauma isn’t just “in your head”; it leaves a very real biological imprint on your body, memory, and brain chemistry. Through somatic (ancient Greek for “body”) psychotherapy and mindfulness-based practices, we will help you find freedom from limiting beliefs, depression, anxiety, and addictive patterns.
-
EMDR is an evidence-based and effective modality for treating trauma and trauma-related symptoms such as depression, anxiety, substance abuse, eating disorders, and PTSD. Our team of trauma therapists takes a somatic approach to EMDR, blending mindfulness practices with somatic therapy and parts work (Internal Family Systems). A regulated nervous system is the foundation for mental well-being.
-
Ketamine therapy is an excellent option if you feel like you’ve tried everything but still feel stuck. It is a safe and legal therapeutic option for treating symptoms ranging from depression and anxiety to OCD and eating disorders.
Ketamine therapy is a science-backed intervention that heals on a neurobiological level, ultimately creating more lasting and transformative change.
-
Psilocybin therapy is a legal therapy that combines the consciousness-expanding properties of psilocybin (“magic mushrooms”) with trauma-focused psychotherapy to create profound transformation for treatment-resistant depression, complex trauma, and existential distress.
At Sona Collective, our facilitators integrate psilocybin sessions with EMDR, somatic therapy, mindfulness, and IFS, providing comprehensive preparation, guided journeys, and deep integration support to ensure insights become embodied, lasting change.
-
Our couples therapists will help you avoid cycling through the same conflict with your partner by providing customized tools and psycho-education for self-soothing, co-regulation, and effective communication to help you move through the “stuck” areas of your relationship.
Our couples therapists will help you navigate the communication breakdown and emotional distance that leads to ambivalence and help you and your partner reconnect with each other.
