Ronald G Macdonald holds Florida licence MRSA2725, 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 2018, which makes it an established licence for the trade in this area. Roughly 29% 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 8 years of continuous licensure.
Ronald G Macdonald is one of 16 active mold inspection licences registered to an address in Miami Lakes, 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.
