Clinical Excellence Meets Precision Longevity

The National Longevity Clinic is the vision of Audrey Elena Ottaviani-Lo Monaco, a certified nutritional practitioner and functional medicine expert, whose own health journey inspired a different approach to healthcare. As the founder, she believes that medicine must restore vitality, not merely treat disease. This philosophy is shared by co-founder Dr Francesco Lo Monaco, an award-winning cardiologist whose career bridges rigorous science and compassionate care.

Twice honoured at the European Awards in Medicine (2022 & 2024) and named Fluxx Global Cardiologist of the Year 2025, Dr Lo Monaco has earned over 500 five-star reviews and recognition among the top 10 percent of clinicians in London. Yet the story goes deeper than accolades.

Together, they built a clinic where science meets soul, blending precise diagnostics, evidence-based protocols, and profoundly personal care to help each patient reclaim their health and longevity.
