What’s in a name?
I started 4th Street Medical because I believe we deserve more than reactive healthcare.
We deserve a system that helps us stay well, not just get treated when we’re sick. My mother was the founder of 4th Street Bodyworks — a passionate entrepreneur and community leader who inspired others through movement, vitality, and nutrition. When she was diagnosed with Alzheimer’s at 58, it came out of nowhere. Over the next 14 years, I watched her slowly decline. Only later did we learn she carried the APOE 4/4 gene and that her two sisters, also gene carriers, would face the same diagnosis. But one sister, who made major lifestyle changes, has maintained her cognitive health well into her 70s.
That changed everything for me. I learned I carry APOE 3/4 myself — and I realized that Western medicine was waiting for diagnoses instead of working to prevent them. 4th Street Medical was born from the belief that we can do better. That we must do better. Through personalized care, advanced diagnostics, and proactive lifestyle interventions, I’m committed to helping people extend not just how long they live — but how well they live.
