About Dr. Roos

I have been in clinical practice since 1997 and working as a specialist physician (internist) since 2004. My journey into Functional Medicine was shaped by two profound experiences.
For years, I thrived in a fast-paced lifestyle—long working hours, frequent after-hour calls, and the demands of both my career and family life. Over time, however, I noticed a gradual decline in my vitality, resilience, and energy levels. I wasn’t sick, but the spark, brightness, and vibrance I once had were fading. More and more, I needed breaks to recharge.
I wasn’t alone. I saw the same patterns in my colleagues, friends, and even teenagers—a world full of tired people. I had unknowingly become accustomed to suboptimal health. The slow decline felt normal, but deep down, I knew it wasn’t inevitable. I wasn’t willing to accept aging as a loss of vitality. That’s when I immersed myself in Functional Medicine, searching for ways to create abundant health and well-being.
Through years of research, testing, and learning from the world’s leading experts in longevity and anti-aging medicine, my entire perspective transformed. The future of healthcare is here. We are at the edge of a healthcare revolution, where advances in science and medicine are giving us the tools to prevent, reverse, and treat chronic diseases long before symptoms appear.
Too many people spend the final decades of their lives in poor health, believing it to be an inevitable part of aging. But most chronic diseases of modern life begin years—sometimes even decades—before symptoms appear. Many are completely preventable, and prevention is always better than cure. Once the body reaches a state of decompensation and failure, restoring health becomes far more difficult.
But this journey isn’t just about me—it’s about us. It’s about collaboration, partnership, and transformation. Together, we can redefine what health and aging look like.
