GST Micro

GST Micro is a small private U.S. healthcare consulting company focused on pharmaceuticals, diagnostics, anti-infectives, and microbiome-related therapeutic areas. Public references describe the firm as providing consulting support to pharmaceutical and diagnostic companies across preparatory, medical affairs, commercialization, and post-approval activities, rather than operating as a drug-development biotech with a disclosed proprietary pipeline. The company appears particularly active in infectious disease, antimicrobial resistance, Clostridioides difficile, and live biotherapeutic product topics through the work of partner Glenn S. Tillotson. Available business-directory data indicate the company is organized as GST Micro LLC in Virginia and remains active. Overall, GST Micro is best characterized as a niche life-science consulting business serving pharma and diagnostics clients.
