Brett ZettleBrett Zettle leaving CMED is not a big deal in any regards. Aurora was involved in a takeover that CMED fought aggresively. Weather Mr Zettle cashed out...or was going to be fired and allowed to take resignation instead, or there was bad blood. I can assure you he didn't just up and leave one morning. Aurora had plans for his position to be filled by one of their own..is my opinion.
