About Me


Dr. Marianne O'Leary PhD
Dr. Marianne O’Leary PhD.
Licensed Psychologist

I received my Ph.D. in clinical psychology from Vanderbilt University, and completed my internship at the Baltimore VA Medical Center. In my postdoctoral training, also at the Baltimore VA, I gained additional experience in geriatrics and primary care. I have worked in a variety of outpatient and hospital settings, including a mental health center, college counseling center, inpatient psychiatric units, and a substance abuse treatment program.

Over the years, I have developed a special interest in working with people who suffer from anxiety in all its forms, including OCD, generalized anxiety, social anxiety, and panic disorders. I work a great deal with mood disorders, and have cultivated a longstanding specialty in trauma recovery/PTSD. I have been trained in and use EMDR. I also enjoy working with older adults, addressing such challenges as caregiving and grief, and I help clients with issues involved in parenting young adults.

One of the most influential schools of thought that I draw from in psychotherapy is cognitive-behavioral. According to this approach, which has been extensively studied and validated, the way we think about issues in our lives, and the actions that we take or avoid taking, profoundly influence our emotions. In collaboration with you, I combine tried-and-true cognitive-behavioral strategies with mindfulness-based approaches to help you develop new patterns of thinking, feeling, and behaving.

Solution-focused approaches emphasize the fact that we all have strengths, and it is often the case that building upon these strengths allows us to be more effective as people and in our relationships. Finally, interpersonal approaches raise our awareness that the ways in which we interact, often learned in our earliest relationships, may shape how we feel and think about ourselves today.

I am a member of the Maryland Psychological Association, the American Psychological Association, the Anxiety and Depression Association of American, the International Society for the Study of Trauma and Dissociation, and the Association for Behavioral and Cognitive Therapies.
