Dr. Denny-Brown is a highly trained pediatric cardiologist who provides the utmost pediatric and fetal heart care. He guides families down the right path for common cardiovascular concerns such as a heart murmur, hole in the heart, chest pain, or a family member with heart disease, as well as for patients with complex congenital heart disease or those at risk of sudden death. Dr. D-B offers his expertise on not only diagnosing and treating heart disease early, but also how to prevent it, which he believes is especially important for the young patients he takes care of.

While he has been in the Los Angeles area for over 8 years now, he is originally from Virginia where he earned his medical degree from Eastern Virginia Medical School. He then moved to California to train at one of the top children’s hospitals in the country – Children’s Hospital Los Angeles – where he completed his internship, residency, and pediatric cardiology fellowship.

Dr. D-B has extensive research experience through his work at Johns Hopkins Hospital, the National Institutes of Health, Massachusetts General Hospital, and Children’s Hospital Los Angeles, and he is an author of multiple publications. He has also served as a reviewer for the peer-reviewed medical journal Pediatric Cardiology. He is a member of the American College of Cardiology and Fetal Heart Society, and a Fellow of the American Academy of Pediatrics.

Dr. D-B is fluent in Spanish and can care for his Spanish-speaking patients in their native tongue. He provides specialized care in all aspects of pediatric and adult congenital cardiology, with particular expertise in echocardiography (cardiac ultrasound), fetal cardiology, high blood pressure and cholesterol management, preventive cardiology, and cardiac critical care.
