If you’re struggling with OCD, Functional Neurological Disorder (FND/FNSD), or PANS/PANDAS, specialized, evidence-based treatment can help improve symptoms and daily functioning.
I specialize in the assessment and treatment of OCD, FND/FNSD, and PANS/PANDAS, working with complex and often treatment-resistant presentations. For OCD, I use Exposure and Response Prevention (ERP), the gold-standard treatment for obsessions and compulsions. For FND/FNSD and PANS/PANDAS, I use CBT-informed and functional rehabilitation approaches focused on symptom retraining, nervous system regulation, anxiety reduction, and restoring functioning.
I am often sought out for consultation on complex FND/FNSD and PANS/PANDAS cases, particularly when symptoms are layered, atypical, or have not responded to prior treatment. My focus is on clear formulation and structured, evidence-based intervention in these presentations.
As a solo practitioner, you’ll work directly with me throughout treatment, ensuring consistent, individualized care. My approach is structured, active, and skills-based, with an emphasis on practical strategies that translate into daily life.
If you’re seeking ERP for OCD or specialized care for FND/FNSD or PANS/PANDAS, I invite you to reach out.
