The primary purpose of the org form is for the board and the public to know where a licensed surveyor is employed. If you are associated with a firm, it is my opinion you should be listed. You can be listed with a couple of firms. If a surveyor named "John Smith" does some work, and that is all the person knows, the public needs to know where to find him.
Please note there is a disassociation form:
