I am a dedicated psychiatric nurse practitioner with over 20 years of experience in both acute care and psychiatric nursing. In my practice, I believe that understanding your issues is the first step toward healing. I take the time to truly listen to your experiences, validating your feelings, and recognizing the weight of what you’re going through. With a holistic approach to psychiatric and medical management, I specialize in the medication management of ADHD, Anxiety, OCD, Trauma, Borderline Personality Disorder, Depression, and Insomnia.

I provide medication management for mental health conditions. I do not provide therapy only.

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.

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.

The core of my success has always been my ability to help people to efficiently and effectively achieve their goals. I look forward to meeting you.
