Obsessive-compulsive disorder therapists & psychiatrists in Arlington, MA

Welcome! I am a licensed mental health therapist with eight years of experience specializing in trauma, personality disorders—particularly narcissism—mood disorders, and relationship challenges. I am trained in EMDR, IFS, DBT, and CBT, though my primary approach is EMDR therapy. I also collaborate with a skilled nurse practitioner to offer integrated support, including ketamine-assisted therapy when appropriate. My goal is to provide a compassionate and personalized path toward healing and growth. I look forward to working with you!

I’m Dr. Olivier Barthelemy (“Dr. Ollie”), a licensed clinical psychologist who works with adults and adolescents facing challenges such as anxiety, obsessive-compulsive disorder (OCD), depression, trauma, and major life transitions. Many of the individuals I work with feel stuck in cycles of worry, self-doubt, or persistent thought patterns that are hard to break.

I strive to create a structured and compassionate space where we can make sense of these experiences, reduce distress, and develop practical tools for lasting change. My approach is also informed by a strong foundation in neuropsychology, shaped through training at Boston University's Center for Anxiety and Related Disorders (CARD) and the VA Boston Healthcare System.

This background deepens my understanding of how brain function and behavior interact, enriching both therapy and assessment. Drawing on both science and empathy, I’m committed to helping clients restore balance, strengthen resilience, and move forward with greater clarity and confidence.

I’m a Licensed Mental Health Counselor (LMHC) who specializes in working with adolescents, young adults, and the families who love them—especially when things feel like they’re at a breaking point. In my past full-time role, I worked in a residential treatment setting supporting teens and young adults facing challenges like anxiety, depression, behavioral issues, substance use, ADHD, and family conflict. I’ve sat with families during some of their hardest moments—crisis calls, treatment decisions, school refusal, shutdown, and explosive behavior—and I understand how overwhelming and isolating it can feel as the person of concern and parent. What makes my work different is that I don’t just focus on the individual—I work with the system. I help parents and young people rebuild communication, restore trust, and create real, lasting change at home, not just in a therapy room.

If you’re feeling stuck, burned out, or unsure what to do next, you don’t have to navigate it alone.
