GMP Audits & Inspection Readiness

Ahead of a regulatory inspection, customer audit, or due-diligence review, I conduct on-site gap assessments and GMP/vendor audits, and help draft your response when findings need to be addressed — including direct experience responding to FDA Form 483 observations and deficiency letters.

Engagement Scope & Deliverables

  • Gap assessment and pre-inspection audits
  • GMP, vendor/supplier, and data integrity audits
  • FDA Form 483 and deficiency-letter response support

Where I’ve Done This Work

Across my career — Site, supplier, and laboratory audits

I have audited most of the internal operations I was responsible for, plus more than 21 outside laboratory services, contract manufacturing facilities, and manufacturing facilities for cGMP compliance, reporting the compliance gaps in official audit reports. I have also developed audit programs covering internal, external supplier quality, and contract laboratory services.

Across my career — Governmental inspections

I have supported site leads through governmental inspections, including FDA, DEA, and other governing bodies, and responded to FDA Form 483 observations, deficiency letters, and inquiries.

Lilly Research Laboratories — Eli Lilly and Company

I took part in pre-approval inspections, facing FDA and EU regulatory bodies, and provided support and responses to regulatory agencies during pre-approval inspections and after launch.

Johnson & Johnson Global Source Quality / WuXi Therapies

I co-audited contract manufacturing sites, worked with site management on audit reports and remediation planning, followed up on audit responses, and monitored quality trends as sites implemented their quality systems.
