As I've said before, this looks like a pretty professional setup. If it was being handled by an outside brokerage firm, I believe that firm would have to disclose its involvement. (I'm not familiar with NY real estate law, that would be true in most, if not all, parts of the US). Since such a firm is not disclosed, the must be handling it in house. Given the professional look, I'm guessing they found some JW with commercial real estate experience and put him in charge.
Confidentiality and Non-disclosure agreements are standard practice in transactions like this.
