Professional Statement

Dr. Mary L. Brandt is a dedicated educator and recipient of numerous teaching awards. Dr. Brandt is committed to care for the specific children entrusted to her in an ethical, thoughtful, compassionate, and competent manner; to advance and improve the surgical care for future children; and to teach the next generation of physicians to strive for excellence in clinical care by teaching and by example. Dr. Brandt is Board Certified in Surgery, Pediatric Surgery, and Surgical Critical Care.

Dr. Brandt cares for a wide variety of surgical problems in newborns and children. Although the majority of her practice, like all pediatric surgeons, is devoted to common problems such as appendicitis, reflux disease, and hernias, she has specific expertise in bariatric surgery for morbidly obese adolescents, newborn surgical anomalies, anorectal malformations, Hirschsprung’s disease, biliary tract disease and thyroid surgery in children.

Dr. Brandt is director of the William J. Pokorny Fellowship and mentors residents and students in the design and implementation of pediatric surgical clinical studies. She is also the primary BCM investigator for several NIH multi-center research grants focusing on adolescent bariatric surgery as a treatment modality for morbid obesity. An industry-funded multi-center study on which Dr. Brandt is the BCM principal investigator studies necrotizing enterocolitis, a neonatal gastrointestinal disease. She is a co-investigator on a national study of biliary atresia.
