Isabelle Parker, MA

Isabelle Parker earns her Psy.D. from William James College in August 2025. Her dissertation asked the question: how do social reactions to trauma disclosure impact the relationship between the cognitive processing of trauma and posttraumatic growth in college sexual assault survivors? She is completing an APA-accredited internship at the University of Connecticut where she works with college students, co-leads a support group for graduate students, and conducts clinical supervision. Throughout her training, Isabelle has served individuals who have experienced trauma, anxiety, depression, ADHD, Autism, grief, as well as relationship and family stress.  

During her postdoctoral fellowship, Isabelle will further train in Cognitive Processing Therapy (CPT) and Acceptance and Commitment Therapy (ACT) for trauma, as well as expand her knowledge on how to best meet the needs of teenagers and adults with neurodivergence, especially those with overlapping Autism and ADHD. In addition, she is interested in learning more about adolescent and adult women’s hormone changes and their impact on ADHD symptoms, anxiety, and mood.  

Isabelle blends the CBTs, including ACT and Dialectical Behavioral Therapy (DBT) with present moment awareness, offering each client a personal, compassionate, science-based approach. She is passionate about building a warm, authentic therapy relationship while working from a client-centered, trauma-focused approach. Isabelle views therapy as a collaboration between the therapist and client, where the client’s pain is witnessed, their joy is shared, and their humanity is celebrated.
