Andrew Santanello, Psy.D. Ext. 5

Andy headshot

Andy Santanello, Psy.D. is a licensed Clinical Psychologist in Maryland. Early in graduate training, Dr. Santanello was shocked to learn that many people struggling to cope with anxiety disorders and depression did not have access to cognitive-behavior therapy (CBT) despite the strong scientific support for this type of treatment. This revelation fostered a strong sense of responsibility to learn CBT interventions, to deliver CBT to his clients, and to teach CBT interventions to his colleagues. Toward that end, he trained with Dr. Jonathan Grayson, a national expert in CBT for OCD, while still in graduate school and went on to learn several evidence-based psychotherapies as a trainee and staff psychologist in the VA system.  As a staff psychologist in the Trauma Recovery program in the Veterans Affairs Maryland Health Care System, Dr. Santanello completed intensive training in Prolonged Exposure Therapy (PE) for PTSD, Cognitive Processing Therapy (CPT) for PTSD, and Cognitive Behavior Therapy for Depression (CBT-D). Dr. Santanello also received training in Acceptance and Commitment Therapy (ACT) and Mindfulness-Based Cognitive Therapy (MBCT) for Depression during his time at the VA. For over a decade, Dr. Santanello provided evidence-based psychotherapy for trauma, anxiety, and depression to veterans in both outpatient and residential settings in the VA system.In addition to direct clinical care, Dr. Santanello also served in a variety of leadership roles during his tenure at the VA, including Regional CPT Trainer for VA clinicians in the Maryland and DC area, team leader for the Serving Returning Veterans Mental Health program, Program Manager for the PTSD and Substance Use Disorders Psychosocial Residential Rehabilitation Program, and Local Evidence-Based Psychotherapy Coordinator at the Baltimore VA Medical Center. As a member of the training staff, Dr. Santanello trained many psychology interns and post-doctoral fellows in evidence-based psychotherapy for trauma, anxiety, and depression during his time at the VA.

Since leaving the VA in 2015, Dr. Santanello has continued to train mental health professionals in evidence-based psychotherapy for PTSD. He is a National Trainer in Cognitive Processing Therapy for PTSD.

Dr. Santanello has expertise in providing cognitive-behavioral therapy for trauma disorders, anxiety disorders, and depression. His specific areas of interest include PTSD, trauma and stress-related disorders, social anxiety, phobias, worry, grief, coping with major life transitions, and major depressive disorder. In addition to work with civilians, Dr. Santanello continues to be passionate about providing the best possible care to our nation’s active duty service members and veterans.
