The current healthcare system was designed to treat disease. Prevention has always been secondary. Advanced biomarkers, cardiovascular screening, metabolic analysis, and precision diagnostics now make it possible to identify what is developing before it becomes a diagnosis. We use these tools as a matter of routine, because the evidence for acting early is strong and the window for doing so is finite.

01
Full-scope primary care

We handle everything a primary care physician should: annual exams, cancer screenings, chronic disease management, acute care, and specialist coordination. When outside expertise is needed, we manage it.

02
The new standard

The diagnostics that predict cardiovascular disease, metabolic dysfunction, and hormonal imbalance years before symptoms develop are available now. We use them as standard practice.

03
Built around you

Every patient has a different relationship with their health. Some want advanced diagnostics and a detailed risk profile. Others want to know their baseline is covered. The plan starts there.

About

Dr. Conor O'Day is a Family Medicine physician trained at Brooklyn Hospital Center in New York City. He built this practice after watching people he cared about navigate a fragmented system, cycling through primary care physicians who never quite had the time.

O'Day Medical Group was built to solve that.
