Built by a mariner, for mariners

Experience behind every credential case.

MMC Credential Concierge was founded by Captain Larry Tompkins, a working U.S. merchant mariner and U.S. Navy Gulf War combat veteran.

After more than three decades at sea, he understands what a credential means to a mariner's livelihood—and how costly missing, unclear, or incorrect application information can become.

We help organize and prepare credential applications. We are not the National Maritime Center, do not issue credentials, and cannot guarantee approval or processing time.
