Since then, Dr. Ramirez Alcantara has remained active in the ALD research and patient community. She is one of only a few pediatric endocrinologists in the world with direct research and clinical experience with this disorder and frequently presents at national and international meetings organized by ALD Connect, as well as the Pediatric Endocrine Society and Endocrine Society annual meetings.
