Matthew David Mcwilliams holds Florida licence MRSA4322, 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 2022, which makes it a relatively recent licence for the trade in this area. Roughly 58% of the 89 active mold inspection licences based in the Port St. Lucie & Treasure Coast area were issued earlier than this one, and the local median sits at 2020. That is 4 years of continuous licensure.
Matthew David Mcwilliams is one of 5 active mold inspection licences registered to an address in Palm City, 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.
