For forty-five years, Jonnie and Thomas Brown built a life together. They supported each other through college, marched together to receive their degrees, formed a family, traveled, and shared the love of a lifetime. When Thomas fell ill on a trip to Florida, everything changed. He was admitted to a local hospital where, within days, he died-the victim of neglect and treatment below the medical standard of care. In You Promised to Do No Harm , Thomas's widow, Jonnie, tells their shocking personal story, shedding light on implicit bias and detailing the struggle that people of color face when equal treatment doesn't apply. It's a call for families to advocate for their loved ones, for the medical community to consciously understand how bias affects their decision-making, and for each of us to address healthcare disparity to keep our loved ones alive.
