Founder, VitalDecades
90 guides published
Mario Bailey founded VitalDecades and answers for every guide on it. He is a software engineer with more than a decade of experience building secure, reliable systems, and a U.S. Air Force veteran. He runs the site's data pipelines and its source checks: each number is read against the guideline, label or public record that sets it, and that source's date is printed beside it.
He is not a clinician, and no named clinician reviews this site yet. How pages are checked sets out what the checks cover and what they do not.
