Our Story

“As a critical care physician for the past 18 years, I’ve witnessed the unfortunate consequences of delayed diagnoses. My clinical experience and research revealed that incidental imaging findings often identify early disease. This insight led me to create B4 Symptoms, an organization dedicated to improving physician and patient outcomes, that lead to better health and improved quality of life.”

Lee Gazourian, MD | Founder & CEO
