Back in 2007, Dr. Gentles, who had worked at Texas Children’s Hospital, teamed up with Bryant, a friend from church who had worked as a consultant on technology implementation and training, to start an urgent-care center just for kids. Today, NightLight Pediatric has eight pediatric urgent-care locations, with 130 employees (80% of whom are people of color) and revenue of $11 million last year. An alum of our 2017 Small Giants list, the company remains entirely owned by its three founders.
