Dr. John Steinberg and Dr. Paul Giannandrea have created a true Dual Diagnosis and Co-Occurring Disorder treatment program in The Bergand Group. Two complementary doctors formed the Berg and Group to provide a setting where patients can be treated, and clinicians can work in a way that embodies the core principles. Both Dr. Steinberg and Dr. Giannandrea have over 40 years of practice experience. As a past president of the Maryland ASAM chapter and the physician who developed the first addiction medicine programs at GBMC in 1986, Dr. Steinberg has extensive experience in the addiction field. As a former Assistant Professor of Psychiatry at the University of Maryland School of Medicine, Dr. Giannandrea developed a comprehensive system of care through the Practice Association that included the Employee and Professional Assistance Programs, VA Drug Dependency Program, UMMC outpatient clinics, and Pathways Treatment Center, that treated a diverse population with both psychiatric and addiction illnesses. Dr. Giannandrea has extensive experience in both the addictions and psychiatric fields.
