Pronouns: He/Him/His

Dr. Marshall is the director and founder of Cambridge Psychology Group and Lecturer in Psychology at Harvard Medical School. His vision for CPG is to create a community of expert, evidence-based therapists who share similar values, want to support each other throughout their careers, and enjoy providing care to clients within a team of professionals.

Clinical Expertise

Dr. Marshall manages many aspects of CPG, including program development, training, and supervision, but he also enjoys keeping an active practice as a clinical psychologist. He treats adults and youth with anxiety, OCD, depression, adjustment difficulties, ADHD, and substance use problems, among other conditions. His approach is grounded in evidence-based practice, which means that he integrates your values and preferences, current scientific evidence, and his clinical experience. He focuses on Cognitive Behavioral Therapy (CBT), Exposure Therapy, and Acceptance and Commitment Therapy (ACT), and he often incorporates aspects of Dialectical Behavior Therapy. He strives to be a friendly, thoughtful, and collaborative clinician. Therapy with Dr. Marshall is built on a supportive relationship through which skills are developed and sustainable change can be made.

In addition to individual work, Dr. Marshall is passionate about leading therapy groups, which is one reason why CPG provides a large group therapy program. He currently leads the ACT for Anxiety and Depression Group, the OCD Support Group, and two OCD Exposure and Response Prevention Groups.

Training

Dr. Marshall received his PhD in clinical psychology from Ohio University, and he completed his predoctoral internship and postdoctoral fellowships at Harvard Medical School and McLean Hospital. While at McLean, he worked in the Behavioral Health Partial Program providing intensive Cognitive Behavioral Therapy to individuals with a range of mental health conditions. He also worked at the College Mental Health Program, and he trained at the OCD Institute at McLean, which is one of the leading residential centers in the world for the treatment of OCD. He currently serves as a consultant at The Pavilion, which is a center for expert diagnostic assessment and treatment of complex psychiatric conditions at McLean, and he continues to supervise trainees at the hospital.
