Best training that I had in the Home Improvement Services. Dan is a great coach. He provides you with great ideas and recommendations.

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!!

This company is amazing Daniel.Coomesbarry great instructor takes his time very patient with everybody I will honestly recommend this company to everyone.

Dominic and his team at Grosso are the real deal. There are a lot of various types of sales trainers out there, but Dominic has mastered the art of in-home selling for today's world. His content is fresh and each time we host him, he absolutely brings his "A" game! We are a better company because of our investment into our sales and leadership team, and Dominic has made all the difference for NewSouth Window Solutions.

I am honored to have been in the first Grosso University class, along with a group of other great companies. I've been in home improvement sales, since 1997, and have never experienced this caliber of training. Most companies do their best, with what they have to work with and just don't know any better, which is just fine, if you're looking for a mediocre salesforce. Dominic's training is next level and beyond, the A-Z of elite sales methodology, from a proven producer who was passed the torch of the great Rick Grosso's legacy. I look forward to working more with Dominic and his team, and I am grateful for Dan Coomesbarry, Corwin Crockett, and the rest of the talented and expertly trained crew. Keep up the outstanding work, gentlemen!

Chad Howman is a game changer. His straightforward no B.S. approach and commitment to purely getting things done is exactly what we need and he delivers. In our very first online meeting he discovered a solution to a problem that more than paid for the 6 months fee for hiring him. We are excited to see all the additional ways he will bring more Value and help take our organization to a whole new level. If you are looking for the typical weak, superficial, templated coaching that's available everywhere, then Don't call Chad and Don't waste his time. Only reach out to Chad if you are looking to truly take your company to the next level and appreciate a customized solution approach delivered by a coach executing at the Top of his Game.
