ZACH STEEL

The Visionary for Proactive Care

Zach’s journey into diagnostics began in 2014 when he built his first clinical laboratory from the ground up. His hands-on experience in lab operations and close engagement with addiction physicians, clinicians, and treatment center owners fueled his passion for using toxicology as a tool for proactive care. His vision is simple: make diagnostics faster, more accessible, and more actionable for providers.
