Do you feel stuck, anxious, or weighed down by depression — yet can't quite explain why? Many of my clients carry the invisible effects of childhood experiences they never recognized as trauma. They've spent years managing, coping, and pushing through — but something still feels unresolved. I bring both clinical training and personal lived experience to this work. I know from the inside what it takes to move through anxiety and depression — and I offer a roadmap that is evidence-based and life-tested, not just textbook theory. You don't have to stay stuck. There is a way forward
Holding two Master's degrees — graduating top of my class in both — and certified in EFIT and IFS, I specialize in trauma, anxiety, and depression. I understand that childhood experiences often shape us in ways we don't recognize. I offer a therapeutic roadmap that is evidence-based and life-tested, helping clients move from simply surviving to truly living.
I strongly believe in the power of parts work, also known as Internal Family Systems Therapy (IFS). Depending on your individual needs, I also incorporate Emotionally Focused Therapy (EFT/EFiT), CBT, Narrative Therapy, or any combination of these modalities. Regardless of the approach, I will challenge you so you can see things differently. Mówię po polsku.

Many of my clients carry the effects of childhood trauma without recognizing it — it shows up as anxiety, depression, or a feeling of being permanently stuck. Using IFS and EFIT, I work at the root level, not just the surface. My goal is not to help you cope better — it's to help you actually heal.
