Leyniker Giovani Sierra

What this record tells you

Leyniker Giovani Sierra holds Florida licence MRSA5492, a MRSA classification which authorises work as a licensed mold assessor. An "R" prefix means the licence is registered, which limits work to the local jurisdictions that accepted it rather than the whole state.

This licence was first issued in 2025, which makes it one of the newer licences for the trade in this area. Roughly 84% of the 398 active mold inspection licences based in the Miami area were issued earlier than this one, and the local median sits at 2020. That is 1 year of continuous licensure.

Leyniker Giovani Sierra is one of 20 active mold inspection licences registered to an address in Doral, so you have local alternatives to compare quotes against.

The licence is recorded as expiring on 07/31/2028. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
