Who We Are
Praxiom Health emerged from Dr. Marinescu’s recognition that traditional healthcare fails to capture the intricate connections between oral health and systemic wellness. Our interdisciplinary team combines expertise in dentistry, internal medicine, biomarker research, and digital health technology to deliver personalized longevity solutions that extend both lifespan and healthspan.
Our core philosophy centers on the principle that “preserving health is measured by the treatment prevented”—a proactive stance that transforms healthcare from reactive disease management to predictive health optimization.
