When doctors started experiencing a PPE shortage,

this doctor began making
face masks in the USA.

Let's Talk

Mac Barnes, MD, and Co-Founder,
Sanctuary Systems

After COVID-19 struck,

Mac Barnes, MD, devoted 100% of his company’s production capacity to face mask manufacturing.

Mac Barnes, MD, Co-Founder of Sanctuary Systems and Founding Partner of the Montgomery Cancer Center (MCC), was on the frontline when the first COVID-19 cases were confirmed in the US, and the PPE shortage became dire. At that point, Dr. Barnes made the strategic decision to shift production to face masks exclusively.
