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 brings three questions into one daily operating system: who you are, when you perform best, and why you do what you do.
Know Yourself
Start with a DISC assessment you can sharpen with your own writing, such as LinkedIn text or a meeting transcript. Add the optional Big Five check for depth, and note results you already know, like an MBTI or Enneagram type, on your profile.
Know Your Timing
See when you do your best analytical work, creative thinking, relationship building, and decision-making, mapped to your own performance rhythm.
Know Your Purpose
A structured purpose exercise lines up your type, strengths, values, and market position into a clear direction. Do what matters, when it matters.
What it does for you
A DISC profile you can sharpen
Self-report first, then your own writing, like LinkedIn text or a meeting transcript, to check it.
Your best hours, mapped
Peak windows for focused, social, and creative work.
A clear direction
A structured way to line up your personality, strengths, values, and market position.
A read before big calls
A quick daily check-in on your state, so you know where you stand before you decide.
Coaching that fits you
AI coaching that adapts to your DISC style and to how you are doing today.
A one-page plan
A visual plan that maps your purpose, strengths, and next priorities.
Why I built this
I built InPsychNow so every professional could have a personal operating system built around who they are. Self-awareness is the foundation of better leadership, better decisions, and meaningful work.
I am building a personal decision intelligence platform. It shows you who you are, when you are at your best, and what to do about it. Every feature is designed to move you from reacting to deciding on purpose.
