Meet Dr GPT™:
Harvey Castro MD, the Emergency Physician Guiding AI into Healthcare’s Future
Harvey Castro MD, widely known online as Dr GPT™, stands at a rare intersection of frontline medicine and advanced technology. For more than twenty years he has treated patients in busy emergency rooms. Today he also designs AI solutions that reduce medical errors, speed diagnoses, and restore 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 clinical realities into clear AI use cases. After earning his MD from The University of Texas Medical Branch and completing an emergency-medicine residency at St. Luke’s University Health Network, he served as a United States Army Reserve E4 Specialist. He later became CEO of a healthcare system while still working on the ER floor, sharpening his instinct for practical innovation.
Early Voice in the AI-Healthcare Conversation
Author of ChatGPT and Healthcare (2022), the first book to explore large language models in clinical settings.
Speaker with four TEDx talks on AI’s power to humanize medicine, most recently “How AI and Humans Can Revolutionize Medicine Together.”
Media resource with more than 100 live interviews on Fox News, Telemundo, Univision, and Dr. Phil 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 the Singapore Ministry of Health and the Texas Medical Association, helping shape ethical frameworks for generative AI.
Creator of more than thirty medical apps and platforms such as SpeakerPlus AI, PitchPlus AI, and CMEUnion.com.
Strategic advisor to Phantom Space, exploring orbital data centers that will keep health data secure above the clouds.
What “Dr GPT™” Means
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
Vision – Resources – Opportunity.
Human plus AI Collaboration.
Story-Driven Change that anchors every statistic in patient narratives.
Looking Ahead
Harvey Castro MD envisions ambient, multilingual, and multimodal AI that fades into the clinical background like electricity, quietly powering safer and more compassionate care. He is 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 during a simple phone call.
