Who We Are
We are a growing community of doctors, allied healthcare professionals, students and researchers committed to identifying the root causes of modern disease and treating patient health safely and effectively.
Ecological Medicine addresses the interactions between the individual, their environment and their health. BSEM has made major contributions toward the integration of ecological medicine into mainstream medicine over its 40 year history.
