The Why Principle
Not what you have. Why you have it.
That one shift changes everything about how you understand your mental health — and what you do next.
Why can't I focus? Why am I anxious when nothing is wrong? Why isn't my medication working? Why is my memory changing?
For 35 years, Dr. James Greenblatt has researched and treated the root causes behind these questions—not just the symptoms. Seven years ago, he began training clinicians worldwide to do the same, because more people deserve care that actually gets to the why.
Now, for the first time, he's bringing that same question to you.
MENTAL HEALTH HAS A WHY.
A DOCTOR WHO NEVER STOPPED ASKING WHY.
Dr. Greenblatt has treated patients others had given up on — the ones who'd tried medication after medication, diagnosis after diagnosis, without ever getting better. Instead of asking what else to prescribe, he asked a different question: why isn't this working, and what are we missing?
That question led him deep into the science of nutrition, genetics, metabolism, hormones, and the body's role in mental health—research most of psychiatry wasn't trained to consider. It changed how he treated patients. And it changed what he believed the field owed them.
Seven years ago, that belief became a mission. Dr. Greenblatt founded Psychiatry Redefined to train clinicians worldwide in this root-cause approach—because no single doctor, no matter how many patients they saw, could reach enough people alone. Today, thousands of clinicians have trained under Dr. Greenblatt’s work.
But training clinicians was never the finish line. It was the bridge.
Now Dr. Greenblatt is bringing his life's work directly to you—the patients, parents, and families asking the same question he's spent 35 years answering: why? Not to replace your doctor. Not to hand you a diagnosis. But to help you understand the factors that may be driving how you feel, so you can ask better questions, seek the right kind of help, and find care built to last.
35 years of research. 7 years of training the next generation. Now, it's your turn to ask why.
