Harvey Castro MD, widely known online as Dr GPT, stands at a rare intersection of frontline medicine and bleeding-edge technology. For more than twenty years he has treated patients in busy emergency rooms; today he also architects AI solutions that reduce medical errors, speed diagnoses, and return joy to clinical practice.

From Night Shifts to Novel Ideas

Growing up in a bilingual household, Castro learned to switch perspectives quickly—an ability that later helped him translate complex medical realities into clear AI use cases. After earning his MD from The University of Texas Medical Branch, completing an emergency-medicine residency at St. Luke’s University Health Network, and serving as a U.S. Army Reserve E4 Specialist, he rose to CEO of a healthcare system while still working the ER floor. Those bedside lessons sharpened his instinct for practical innovation.

Early Voice in the AI-Healthcare Conversation

• In 2022 Castro published ChatGPT and Healthcare, the first book to explore large language models in clinical settings.
• He has delivered four TEDx talks on AI’s power to humanize medicine, most recently “How AI and Humans Can Revolutionize Medicine Together.”
• National outlets including Fox News, Telemundo, Univision, and Dr. Phil have called on him for 100-plus live interviews that demystify new technology for the public.

Builder, Advisor, Futurist

• Chief Medical AI Officer at Helpp.ai – leading fall-prevention analytics and ambient workflow tools.
• Advisor to Singapore’s Ministry of Health and the Texas Medical Association – shaping ethical frameworks for generative AI.
• Product creator – more than thirty medical apps plus platforms like SpeakerPlus AI, PitchPlus AI, and the forthcoming CMEUnion.com.
• Space-age thinker – strategic advisor to Phantom Space, exploring orbital data centers that keep health data secure above the clouds.

What “Dr GPT” Means

Castro brands himself Dr GPT to signal a bridge between the exam room and the code base. GPT models process language; physicians interpret human stories. Together they form a feedback loop that can predict strokes, personalize discharge instructions, and flag sepsis hours earlier than current norms. Dr GPT curates that loop so technology augments—not replaces—the clinician’s empathy.

Signature Frameworks

1. Vision, Resources, Opportunity – a JFK-inspired structure he applies to every keynote: picture the future, prove we have the tools, invite collective action.
2. Human + AI Collaboration – doctors keep the moral compass; machines handle pattern recognition at scale.
3. Story-Driven Change – real patient narratives anchor every statistic so policymakers feel the stakes as keenly as families do.

Looking Ahead

Harvey Castro MD envisions ambient, multilingual, and multimodal AI that fades into the clinical background like electricity—quietly powering safer, more compassionate care. He is currently writing Healthcare Revolution: How Artificial Intelligence is Transforming Medicine and Patient Care, mentoring global startups, and designing voice biomarkers that may one day flag heart failure through a phone call.
