DAN IS THE MAN! Very knowledgeable and has great advice & tips for anyone trying to better there skills!

As a long time sales professional, trained for most of my career in B2B selling, the Grosso system cements the psychology and tactics of in-home remodeling services selling for me. I was able to identify holes in my closing approach while at the same time embracing my creative, collaborative style. While the system has many familiar parts from many other trainings I have gone through, it's tips on objection take-aways and explanations of customer investment incentives unlocked the secrets of 40%+ close rates for me. Thanks Daniel for an affirming coaching 2 weeks.

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.
