I work for Windows Plus in Louisville and I was apart of a sales boot camp done by Corwin Crockett. The amount of knowledge I learned on how to sell and talk to people was astronomical. I personally liked how Corwin taught me how to sell when I’m not at the most favorable appointments. This has already began to help me at my sales appointments.

Grosso University is the sales academy training that my company used for onboarding. The amount of information in this 2 week class could easily be an entire semester. Dan has the experience to answer any question you could possibly come up with, any scenario and any objection, he can tell you how to handle it. On top of that he is so personable that asking questions is easy. Corporate training that I’ve gone through is nothing like this, you can tell he wants you to succeed and you can tell he is passionate about this. It is a very challenging class, but as Dan has said, the scripts and information that they teach you, will set you up for success. Thank you Dan!

Hands down this is the best sales training I’ve ever been through. Not only did I learn a whole bunch of new tactics and approaches but I now have a whole new concept of selling big ticket items. Dan and Dominic are amazing and very insightful! If you want to blow up your sales volume, get their course. You can thank me later.
