Nereida Gonzalez-Berrios, MD

Dr. Deringer is a psychiatrist with board certification in general psychiatry and addiction psychiatry. She earned her M.D. from the University of Michigan Medical School, and she completed her psychiatry residency and addiction psychiatry fellowship training at New York University. She has previously held faculty roles at New York University School of Medicine and Harvard Medical School. She has been involved in training the next generation of psychiatrists through her past work on the Program Director team for the MGH-McLean Psychiatry Residency Program. She has expertise in treating adults with mood disorders, anxiety disorders, substance use disorders, personality disorders, trauma, and ADHD.

Dr. Deringer cares deeply about understanding each patient's unique experience.  She recognizes that mental health symptoms are impacted by an individual's biological make-up, social situation, and their individual way of interacting with others in the world.  She will assess all of these factors and work with you to develop an appropriate treatment plan to help you feel better and meet your goals.  She incorporates supportive psychotherapy into all of her patient meetings; this may include discussions of the role of nutrition, exercise, and sleep habits in your overall well-being.

Dr. Deringer will begin the evaluation process with a thorough one-hour session in which we will discuss your current symptoms, your prior treatment history, your medical history, and your goals for treatment.  At the end of that session, she will begin to formulate her diagnostic impression and treatment recommendations.  Sometimes, the evaluation process may require more than one session, and it may be helpful for Dr. Deringer to gather information, with your permission, from prior treatment or to collaborate with your therapist if you have one.  Dr. Deringer will work with you on a medication treatment plan, if clinically indicated, to help you manage your symptoms and achieve your treatment goals.
