USCG Drug Testing Clinic Location?

I did mine at Island Medical Center in Sunny Isle on St Croix. Not sure if that is where you are or not. If not, just call the Coasties and they will let you know

I used the same location on STX for my USCG Captain's License drug testing last summer. I don't know where the test is given on STT, but you should be able to find out easily by calling the Captain's School at Red Hook.
