Harley Street’s leading health optimisation clinic, where medical precision meets modern wellness.

Live A Longer, Happier, Healthier Life

Clinical Excellence, Global Recognition

The National Longevity Clinic is the vision of 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% of clinicians in London.

Yet the story goes deeper than accolades. His work is driven by a belief that medicine must restore vitality, not merely manage symptoms. This philosophy is shared by his co-founder and wife, Audrey Elena Ottaviani-Lo Monaco, a certified nutritional practitioner and expert in functional medicine. Together, they built a clinic where science meets soul: blending precise diagnostics, evidence-based protocols, and profoundly personal care to help each reclaim their health and longevity.
