Online Therapy vs. In-Person Therapy for Trauma and Dissociation: Does It Really Make a Difference?
If you’re looking for therapy for trauma or dissociation, you may have wondered whether online therapy is really enough. Maybe you’ve heard that telehealth is convenient, but in-person therapy is “better” for deeper work. Or perhaps you’ve assumed that if your symptoms are more severe, such as significant dissociation, flashbacks, memory gaps, depersonalization, derealization, or symptoms associated with DID or OSDD, you need to see a therapist in person. That assumption is u

DID Treatment Is Evolving
If you've been reading about Dissociative Identity Disorder (DID) for a while, you've probably noticed that there are many different theories about what causes it, how it works, and what treatment should look like. For years, much of DID treatment was based on clinical theories and observations from therapists who worked closely with people experiencing dissociation. A recent 2025 review by Bachrach and Huntjens highlights an important shift in the field: DID treatment is inc

"I Don't Remember It, But Somehow I Do?" Understanding Memory in Dissociative Identity Disorder
One of the most confusing experiences for people living with Dissociative Identity Disorder (DID) is memory. One of the symptoms of DID is having gaps in memory. Many describe feeling this experience as missing pieces of conversations or entire experiences that feel inaccessible. At the same time, they may be surprised when they somehow "know" information they don't consciously remember learning. A 2024 research study by Dimitrova and colleagues explored this exact question.

What Makes Trauma "Complex"?
Not all trauma is the same. A car accident, a natural disaster, a single frightening medical event, these are real traumas, and they deserve real care. But there's a different category of experience that shows up again and again in therapy rooms: trauma that didn't happen once, and didn't happen in isolation. This is what we mean by complex trauma. Complex Trauma vs. Single-Incident Trauma Single-incident trauma is exactly what it sounds like: one event, often unexpected, tha

Structural Dissociation Training for Therapists: The Nesting System Method, a treatment for Complex Trauma and Parts Work
For fellow therapists! I’m really excited to share something I’ve been developing with a lot of care and intention. Over time, I’ve been building a comprehensive framework called the Nesting System Method™, designed to support our work with clients experiencing structural dissociation and complex trauma. This approach offers a way to more clearly understand and work with internal systems, especially when parts hold different roles, needs, and levels of activation. It’s ground

The Nesting System Method
The Nesting System Method™ is an integrative therapeutic approach I developed to support clients with structural dissociation, including dissociative identity disorder (DID), other specified dissociative disorder (OSDD), and complex trauma. Grounded in the principles of EMDR therapy and informed by the Theory of Structural Dissociation, this method uses intentional, continuous slow bilateral stimulation to regulate the nervous system, promote connection with parts holding dis

What Is Structural Dissociation? Understanding Trauma, Dissociation, DID, and OSDD
When people hear the word “dissociation,” they often think of feeling spaced out or disconnected. While that can certainly be part of the experience, structural dissociation describes something much deeper. It offers a framework for understanding how overwhelming trauma can lead the mind to organize itself into separate parts, each with distinct roles, emotions, and memories. For trauma therapists, understanding structural dissociation is essential. For survivors, it can prov

What Is Trauma?
A traumatic event is an experience that the brain perceives as dangerous or a threat to life. Trauma is held in the body and shows itself in a multitude of ways including: spiraling thoughts wondering if you’re good enough or worthy trouble sleeping or sleeping too much panic attacks feeling stiff trouble with memory …and the list goes on. No matter the event, what makes it traumatic is the difficulty of staying present, understanding what’s happening, processing the experien
