There have been a number of fraudulently issued checks bearing the name "Bahnson Mechanical Systems" or "Bahnson Mechan Systems". These checks have been accompanied by a notification that recipients are winners of a "Supermarket Customer Sweepstakes Raffle Draw" and require a "processing fee" in order to claim their winnings. These checks and notices were not issued by Bahnson and are fraudulent.

Should you receive such a check and/or request for a processing fee, you should NOT participate in the process.

If you have already participated in the process, you should notify the appropriate authorities of this fraudulent activity.



Andy Backus, CEO, is just one of the many people that deliver projects that meet our clients most exacting standards. Meet the rest of the team.
