Diversity, Equity and Inclusion
The faculty, staff, and trainees of the Pediatric Cardiology Fellowship Program at Baylor College of Medicine and Texas Children’s Hospital believe that diversity, equity, and inclusion are fundamental to our success. All diversity, including diversity of race, ethnicity, experience, age, gender, geographic origin, sexual orientation, and religion, is celebrated within our program. We aim to recruit and retain diverse individuals and create an environment of unity in which our members learn and benefit from one another while equipping themselves to provide high-quality, culturally competent care to every patient.
