Mark Richard Orso holds Florida licence MRSA5258, 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 2024, which makes it one of the newer licences for the trade in this area. Roughly 73% of the 203 active mold inspection licences based in the Tampa area were issued earlier than this one, and the local median sits at 2020. That is 2 years of continuous licensure.
This is the only active mold inspection licence registered to an address in San Antonio in the current DBPR extract — worth widening your search to the surrounding Tampa area when collecting comparison quotes.
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.
