I have decided to get back into the home improvement business after being out for 8 years. Now after being out of doing any kind of selling in the home i found myself really rusty and using some of the outdated high pressure scripting that was used 20 years ago. I joined the Grosso university jump start program and participated in the 2024 closer camp all i can say is “money well spent” Dom & Dan really break everything down to what selling and closing in the home in an easy and understandable way without all of the outdated sleazy sales tactics. Anyone looking to up the their selling game ether with presentations, Closing, mind set owe it to themselves to invest in the Grosso system. Shout out to Matt for helping getting our company on board.

The proven sales methodology is on point, not easy, but worth the effort! Dan, who was our personal trainer, was extremely effective teacher and I really like his style as a trainer! Positive and supportive while making corrections during coachable moments. Definitely left me with an impression that the system works and he himself is approachable and wanting to genuinely help! It's been a really good 2 weeks! Thank you Grosso University!

Well trained class and very thorough!! I’ve personally been through many different training classes and schools and this is by far the best I have ever attended. Not every trainer I’ve dealt with has even spent a day out in the field as far as what they are training on but these guys have started exactly where I am and they truly know what they are talking about! What I love the most is that they don’t only train you on your job but they focus on making you a better person and their training pertains to your everyday life. Great job guys!!!

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!!

Nothing Works Like This

I'm at my 6-week mark, and you never know what to expect. Being able to ask questions and interact live is extremely helpful. I knew it was good, but I didn't know it was this good. After 15 years in the Marine Corps and attending 10 sales schools, I’ve never seen anything like this.

Effectively Go Up Against Competition

This event was one of the most engaging I’ve attended in a long time, keeping me focused from start to finish. I took plenty of valuable notes that I can’t wait to bring to our sales meeting on Monday. The content was structured with practical, easy-to-implement strategies that fit seamlessly into our daily practices.

Best Sales Training Seminar

My favorite part was focusing on team and personal goals while using the right tools to succeed. I’ve attended other industry sales seminars, but this was by far the best sales training seminar I’ve been to. Dominic’s in-depth research on our products made the training even more informative and impactful.
