Dr. Dolores DiGaetano, MD has been president of Chamberlin Clinic since 1988.  She is certified by the American Board of Psychiatry and Neurology.  In addition to her clinical practice, she has been involved with research at Chamberlin Clinic since 1985 and at CNS Healthcare, Inc. since 2005.  Her clinical practice encompasses psychiatric evaluation, patient and family education, treatment planning, medication management and oversight of the other clinical staff members.  She uses research criteria in making diagnoses and is conservative in medication prescribing.  Dr. DiGaetano is a firm believer in diet, exercise and good sleep hygiene as a basis for good health.  She also encourages her patients to responsibly follow up with their primary care physicians.  Knowing that medication does not solve all problems, Dr. DiGaetano often refers patients for psychotherapy within the clinic or within the local community.
