Dolores DiGaetano, MD
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.

In addition to her clinical duties, Dr. DiGaetano is the immediate past president and the current treasurer of the Tennessee Psychiatric Association.  She has served as president of the West Tennessee Psychiatric Association for two terms.  She is a member of the American Psychiatric Assocation, the Tennessee Medical Association, and the Memphis Medical Society.  She has received the AMA Physician Recognition Award for continuing medical education for the past fifteen years.  She has served on the speakers bureau for several pharmaceutical companies:  Lilly, Pfizer, Wyeth, GlaxoSmithKline, and Bristol-Meyers Squibb.  Dr. DiGaetano is also a clinical instructor for the University of Tennessee Center for the Health Sciences  Department of Psychiatry where she was awarded clinical instructor of the year for 2009.  She was voted by her peers in the Best Doctor survey in Memphis as "the best psychiatrist" in 2011 and 2012.

Dr. DiGaetano feels it is a privilege to serve psychiatric patients:  "It is very gratifying to see people blossom in to who they were meant to be".
