Meet the Team
We Believe That a Strong Therapeutic Container Matters.
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.
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 Are
Beliefs
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 Work
Approach
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 Do
Methods
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.

Couples Therapy
In the safe, nonjudgmental space of couples counseling, you will experience the transformative support of a third-party professional who will help you articulate your inner experience to your partner in a healthy, constructive way. We want to show you how to avoid cycling through the same conflict repeatedly by providing you with customized tools and psychoeducation on self-soothing, co-regulation, and communication so that you can move through the “stuck” areas of your relationship.
Ketamine Therapy
Ketamine therapy has become increasingly popular in the mental health world because of its efficacy in treating depression and other trauma symptoms.
Ketamine creates neuroplasticity in the brain so that new connections can form, which leads to cognitive and behavioral change. We combine ketamine therapy with other trauma-focused modalities for a holistic approach.
Trauma Therapy
Our team uses EMDR, an evidence-based modality, along with somatic therapies to treat complex trauma and PTSD. EMDR has been shown to decrease trauma symptoms and desensitize trauma-related triggers in individuals. We combine EMDR with somatic therapies and mindfulness-based techniques for an effective “bottom-up” approach that regulates and nourishes the nervous system. A regulated nervous system is the foundation for mental well-being.
