1. What inspired you to open a therapy practice focused on trauma in Seattle?

I've always been deeply interested in trauma, particularly the kind rooted in childhood experiences—what's often referred to as complex PTSD (CPTSD). When I decided to specialize in trauma therapy, I explored different approaches like CBT for trauma, Somatic Experiencing, DBT for trauma, and EMDR. EMDR stood out to me as a powerful way of helping people process and heal from trauma. It's not a quick fix, especially for those with extensive childhood trauma. It has structure and an effective path toward healing.

2. What services do you offer?

I work with adults navigating trauma, anxiety, relationship and work challenges, and the ups and downs of everyday life. In addition to EMDR, I incorporate Dialectical Behavior Therapy (DBT), a skills-based approach that helps clients manage emotions, reduce stress, and communicate more effectively. Many of us weren't taught how to handle big feelings or difficult conversations—DBT provides skills to bridge that gap.

3. How does your therapy help people with trauma and mental health challenges?

Some clients come in knowing they've experienced trauma and are aware of its impact. Others arrive feeling anxious, overwhelmed, or stuck in patterns they can't quite explain. I see these symptoms as signals from the mind and body that something deeper needs attention. Together, we work to uncover and heal those underlying wounds.

4. What kind of clients do you enjoy working with?

I love working with adults who feel like their lives are off-track and are ready to make a change—even if that change feels daunting. People don't need to have everything figured out; just a willingness to explore and take that first step is a great place to start.

5. What can someone expect during their first EMDR session with you?

In our first session, we'll discuss your goals—whether it's processing a specific traumatic event or addressing issues like panic attacks. I'll take a thorough history to understand any other significant experiences that might be relevant. EMDR involves several preparation phases before we begin reprocessing traumatic memories, ensuring you feel safe and supported throughout the process. See my blog about the first EMDR session here.

6. What should people know about doing EMDR with you?

It's important to work with a skilled EMDR therapist. I'm a certified EMDR practitioner, which means I've undergone extensive training and consultation. I believe in the principle that "fast is slow"—we won't dive into deep trauma work until you're ready. My approach is to guide you gently, ensuring you feel safe every step of the way.
