Why Firms Trust Criterion
Every expert on the Criterion Panel is fully vetted.

Credential Verification
Licenses, board certifications, current practice status, and institutional affiliations are verified before panel acceptance and re-checked for each case match.
Full Background Checks
Every expert undergoes a thorough background check. Prior adverse findings, disciplinary records, and legal history are reviewed and assessed before any panel acceptance.

All panel members are bound by confidentiality agreements. Your case details and client identity are protected at every stage — from first search to final engagement.
