Dan and Corwin held a terrific 2 week training. Very professional and knowledgeable instructors! Learned more in 2 weeks about human interaction than my entire schooling growing up.

Candy Thomas

Its was awesome and incredibly hard. Its like sales bootcamp with daily mental burpes.

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.

One word to describe this training. ELITE. I’ve been in a few different sales industries through the years with multimillion and billion dollar companies. This was BY FAR the most comprehensive and helpful sales training that I have EVER been through. In the first week I closed a deal where I used a few Grosso talk tracks and techniques. Dan’s professionalism and wealth of knowledge was top tier. He answered questions concisely and his explanations were always relatable and memorable. I highly, highly recommend Grosso University to anyone or any company that is looking to increase their revenue using the one call close!

Dan and Corbin are such amazing teachers!! Could not ask for a better teacher, he did a amazing job teaching us, and breaking down the sales process. I am definitely confident and feel much better about getting out in the field and selling, and doing it in such a authentic comfortable way that would be beneficial to me and my prospects! Selling is something I was very uncomfortable with in the beginning, but he not only showed us how to do it properly, but how to do it in a comfortable way, thanks a million!!
