The Founder

Harvey Castro, MD MBA
Emergency Physician • AI Expert • Author • Speaker
Dr. Harvey Castro is a practicing emergency physician, AI researcher, and serial entrepreneur who has spent over two decades at the intersection of medicine, technology, and human performance. He is the author of 16+ books on AI, healthcare, and personal development, and has delivered 5 TEDx talks and 40+ conference keynotes worldwide.
As the founder of DrGPT and InPsychNow™, Dr. Castro brings a unique clinical perspective to personal development. His medical training taught him that the best interventions are personalized, evidence-based, and timed to the patient. The Cadence Method™ applies those same principles to professional performance.
“In the ER, timing is everything. A medication given at the right moment saves a life. Given too late, it is useless. I realized the same principle applies to every decision we make: when you act matters as much as what you do. That insight became the Cadence Method™.”
The Cadence Method™
The Cadence Method™ is a convergent framework that unifies personality intelligence (who you are), timing intelligence (when you perform best), and purpose intelligence (why you do what you do) into a single daily operating system.
