Why Firms Trust Criterion

Every expert on the Criterion Panel is fully vetted.

We don't accept applications — we screen them. Every expert undergoes a rigorous qualification process before any case introduction.

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.
Confidentiality Agreements
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.
Secure Data Handling
Client data and case information are stored and transmitted with security controls. We treat your case file with the same discretion your firm applies to privileged client communications.
