About Our Founder & CEO
Founder & CEO: Nancy Tuohy
After more than 20 years working across both large healthcare systems and nimble startups, I came to a realization I could no longer ignore: primary care is broken. It’s reactive, disease-focused, and often fails to address the root causes of the chronic conditions that are overwhelming our communities.

As a daughter caring for aging parents and a mother raising two daughters, I saw firsthand how our healthcare system waits for people to get sick—then tries to manage the damage. But what if we flipped that model? What if primary care became the gatekeeper of health, not just the manager of disease?

For years, I hoped someone else would build this new model. I kept working, waiting, and watching. Then one day, while visiting a friend at a senior living community, I saw a woman crying. Her father, who no longer recognized her, had just been moved to a dementia unit. She was told there was nothing she could do. That moment broke something open in me.

There is something we can do. There are so many things we can do—through nutrition, sleep, movement, stress management, and mental and spiritual health—to preserve and even restore our well-being. That day, I stopped waiting. I decided to build the model myself.

It was the biggest decision of my life. But I wasn’t alone. Along the way, I met incredible, like-minded healthcare professionals who shared the same mission. Together, we founded Trueline Health—a new kind of primary care that empowers patients to take control of their health and live with vitality and purpose.

Welcome to Trueline. Let’s build a stronger, healthier you—together.
