Medicine That Looks Beyond the Present
At Longevity Lab MD, we believe healthcare should do more than treat disease after it appears.
Our approach is centered on understanding your health at a deeper level—identifying risk factors early, measuring the biological processes that influence how you age, and creating a personalized strategy to help you feel your best today while protecting your health for the years ahead.
Led by Dr. Margarita Ibáñez de Sendadiano, MD, Longevity Lab MD brings together nearly two decades of experience in Internal Medicine with specialized training and a passion for preventive and age-management medicine.

A Different Approach to Healthcare
Your chronological age tells only part of the story.
Two people of the same age can have very different metabolic health, cardiovascular risk, hormone profiles, muscle mass, body composition and biological aging.
That's why we don't believe in a one-size-fits-all approach.
We measure. We understand. We personalize. We monitor.
Your care may include comprehensive laboratory testing, advanced biomarkers, hormone evaluation, metabolic assessment, body-composition analysis, biological-age testing and other evidence-informed tools when appropriate.
The goal isn't simply to add more tests or treatments.
The goal is to identify what matters for you.
