Praesidio Life Sciences

Praesidio Life Sciences was a privately held Texas healthcare company formed in 2020 during the COVID-19 pandemic to source and distribute rapid COVID-19 antibody screening tests in the United States. Public descriptions consistently present the business as an early-response diagnostics company rather than a drug-development biotech, with activity centered on commercializing imported serology tests for health systems and state agencies. Available records tie the company to Plano/Dallas, Texas and to manager Mark DeCourcy. Evidence of ongoing operations appears limited and recent public footprints are sparse, so the company appears inactive as an operating business. No conventional therapeutic pipeline, proprietary drug platform, or clinical-stage pharmaceutical programs were identified.
