I tried to look up the team that they brought in to give the training, but I couldn't find them. It was several years ago, but I remember that the main guy was one of the more popular authors. He had a series of books written that ranged from basic to advanced skills. I wish I could remember his name. The books are probably useful (there are a ton of them), but the live sessions are likely much more effective because you get to practice the techniques, see the subtleties, and experience the results directly. For me, seeing the results really helped train my brain. Honestly, I went into the training dragging my feet and expecting the worst, but it's given me a huge edge. The results have been amazing - especially when negotiating with unskilled negotiators. I've gone into negotiations expecting X and consistently getting 2X, sometimes even 10X.
