I was part of the first Grosso University Sales Academy and I cant speak more highly of Dominic and his team for the training he put on. Ive been through numerous sales training seminars and classes and none of them came close to the caliber of this course. If you want to take yourself or your team to the next level, I would highly recommend reaching out to Dominic at Grosso University to schedule training with him.

This was the second time that I have had the pleasure of attending Dominic's sales training and he did not disappoint! He is a very skilled and inspirational leader, very well-spoken and his sales skills are second to none. Thanks again for joining us in Florida to deliver your brand of wisdom to our Sales Leaders!!!

I just finished this class today and it was really filled with invaluable information. In two weeks, I learned enough about the sales process to feel confident in my career moving forward. Dan and Corwin were amazing instructors that brought humor, experience and personality to the class and gave a ton of personal stories and sales tips that I cannot wait to put into action! I would highly recommend this class to any sales professional at any level to continue to learn and get better at their craft! Thanks guys!!!! 👍👍

I have attended the closers camp this year In Nashville and also had the benefit of Dominic coming to our office for a two day program tailored for our products . It was the best training I received in years of sales . Real tools you can use to achieve your goals . If you have the opportunity to attend one of his events or check out the online content , dont hesitate!

Dan did an incredible job of presenting, quizzing, and injecting humor in our comprehensive training.

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.
