David Michael Patterson holds Florida licence MRSR2266, a MRSR classification which authorises work as a licensed mold remediator. 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 2011, which makes it a long-held licence for the trade in this area. Roughly 1% of the 147 active mold remediation licences based in the St. Petersburg & Clearwater area were issued earlier than this one, and the local median sits at 2020. That is 15 years of continuous licensure.
David Michael Patterson is one of 30 active mold remediation licences registered to an address in St Petersburg, so you have local alternatives to compare quotes against. David Michael Patterson additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.
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.
