Worldborne pairs clinical judgement with disciplined execution. A physician signs the work; an operator makes the engagement run.
U.S.-trained physician · Internal Medicine background
Dr. Thomas A. Hatzilabrou, M.D. is a U.S.-trained physician with a background in Internal Medicine. He founded Worldborne Medical on a single operating principle: a health claim is verified against a primary source.
His practice today is the accuracy, review, and presentation of health information — strategic audits of health organizations built from federal data and public filings, evidence-based review of HCP-directed and promotional documents, original physician-authored whitepapers, and regulatory compliance review for companies whose content must withstand scrutiny. Every engagement is scoped as fixed, per-item deliverables, and every deliverable ships with its sources attached.
Operations, quality & risk across regulated industries
Sarah J. Welborn is Head of Business Development at Worldborne, where she connects the firm's clinical expertise to the organizations that need it most. She brings an operator's breadth — a career spent building, refining, and de-risking how complex, highly regulated businesses actually run, from the front line to the boardroom.
Her background spans operations, training, quality management, risk analysis, and compliance across some of the most demanding sectors there are — insurance, banking, healthcare, logistics, manufacturing, and R&D. She scopes each engagement with precision, safeguards quality at every step, and turns a first conversation into a lasting working relationship.
