    Dr. O’Sullivan is the Director and a clinical supervisor at Trinity Psychological Services.  She practices out of the Orangeburg, NY and Ridgewood, NJ locations as well as providing virtual services.

    Services and Specialties:

    I specialize in providing
         Psychotherapy (CBT/REBT) for children through adults
         Perinatal mental health focused psychotherapy
         Parent training/support
         Neuropsychological evaluations
         Autism diagnostic evaluations

    I work with children through adults and love to help my clients learn new tools to help them manage difficult emotions, including anxiety, depression, perinatal mood disorders, and emotional dysregulation while also learning about their strengths and weaknesses.  In addition, I am a maternal mental health trained professional through Postpartum Support International (PSI).  

    I like to view the range of services I provide as helping children and families.  I love to have variety in my specialty areas and have invested my time and energy to develop specific skills to address each specialty area.
