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.
As your therapist I will work alongside you to help you learn to identify your emotions, learn healthy ways to express yourself, and healthy and effective ways of communicating with others. Together we will also identify your strengths as well as possible unhealthy thinking or behavioral patterns and how they relate to your everyday experiences and emotions.
Great to meet you!
As a Licensed Clinical Social Worker, I believe prioritizing mental health is key to happiness and stability in life. Asking for help can be one of the toughest challenges, so congratulations on taking that first step! I’ve been practicing for 10 years, and my main focus are adult clients who are struggling with PTSD, anxiety and depression.

Life doesn't come with a manual and it can be a lot sometimes...
Going through a life transition - career/job change, relationship status recently updated, loss - healing old wounds, or just trying to "keep it together"?
Let's chat. In our work together, you can expect a supportive space where you don't have to have it all figured out (and you don't have to figure it out alone). Therapy can be helpful - let's give it a try.
If you've ever felt like you're moving through life a little out of sync with yourself, like something is pulling you off course and you can't quite name it, you're not alone. And you're in the right place.
I'm a Doctor of Nursing Practice and Psychiatric Advanced Practice Clinical Nurse Specialist, and my approach to care is anything but one-size-fits-all. I believe that true healing happens when we tend to the whole person, your mind, your body, and your spirit, and that you already hold a lot of the wisdom you need. My job is to help you access it.
