Ben Barnes, PhD is the founder/owner/operator of Eastern Massachusetts Personalized Behavioral Health, LLC.


Dr. Barnes earned his PhD in clinical psychology from the University of Delaware and completed a two-year clinical fellowship in the PTSD Clinical Team at the VA Boston Healthcare System with supervision from faculty at the National Center for PTSD and Boston University School of Medicine. He worked in a research laboratory with Dr. Brett Litz, PhD, Director of the Mental Health Core of the Massachusetts Veterans Epidemiology and Information Center, MAVERIC. At MAVERIC, also located at the VA Boston, Dr. Barnes studied Posttraumatic Stress Disorder (PTSD) and comorbid challenges in Veteran populations. Dr. Barnes has been working clinically with mood disorders (anxiety and depression) and trauma for over 10 years. He has worked with some of the leading developers and researchers of evidence-based treatments for anxiety disorders (e.g., generalized anxiety disorder, obsessive-compulsive disorder), PTSD, and depression at the Universities of Massachusetts, Delaware, and Pennsylvania, and the VA Medical Centers of Philadelphia and Boston


Furthermore, he has co- and lead-authored several peer-reviewed journal articles, academic book chapters (below), and professional conference presentations related to these behavioral health problems. These experiences have contributed to Dr. Barnes’ knowledge of, and expertise in delivering state-of-the-art, evidence-based treatments for anxiety- and trauma-related disorders. His years of clinical experience have cultivated his ability to provide evidence-based cognitive-behavioral therapy that it strongly rooted in a collaborative relationship and responsive to the individual needs of clients. 

Dr. Barnes is also the Medical Director of Behavioral Health Research at Reliant Medical Group. In this role, Dr. Barnes oversees assessment and intervention research across Reliant's more than 300,000 patients.
