Behind every hospital door lies a world few truly see. The Glass Barrier offers an unfiltered look into the pediatric ICU—not from the bedside, but from the front desk, where humanity, hierarchy, and perception intersect in ways often overlooked. Positioned at the threshold between life-altering decisions and everyday operations, Dr. Dionne A. Taylor recounts the moments that unfold in real time—moments of grief, resilience, bias, and unspoken. Through deeply personal reflections and professional insight, this book explores the invisible boundaries shaped by identity, role, and systemic bias within healthcare. It challenges readers how perspective influences care, communication, and outcomes—not just for patients and families, but for those navigating the system from within. This is more than a story about healthcare. It is a story about being seen—and unseen—at the core.
