As part of the Pioneers in Pediatric Psychology series, this article provides a brief personal account of my career as a pediatric psychologist. Educational and professional experiences often involved confrontations with silos and boundaries set by traditions limiting understanding and impact on children’s healthy development. A pedigree in developmental psychology clashed with identity, guild, and loyalty dimensions of clinical psychology. A research emphasis challenged the emergent harmony of the scientist–practitioner models. The medical center and its silos collided with those of arts and sciences academia. Evolving as an applied developmental scientist specializing in pediatric psychology allowed for a gratifying and meaningful career with a range of scientific, pedagogical, and policy contributions. An abiding orientation toward human rights and social justice sustained progress and generativity.
