Had Dan come come out to run with my new reps. What a game changer! Having someone so knowledgeable and good with new reps made a big difference. Can’t wait for the next sales academy class.

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!!!! 👍👍

Dan Coomesbarry is both entertaining and knowledgeable whilst communicating the most comprehensive and in-depth sales training program I’ve had the opportunity to attend. I’m excited to put into practice what I have learned. Thank you Grosso University!

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 Now after being out of doing any kind of selling in the home i found myself really rusty and using some of the outdated high pressure scripting that was used 20 years ago.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break everything down to what selling and closing in the home in an easy and understandable way without all of the outdated sleazy sales tactics.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.

Trained via zoom with Dan. This comprehensive sales training is well prepared, written, and taught. You get the confidence to enter a home and get the sale at the kitchen table. Thank you Dominic, Dan, and the GU team.

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.

Was involved with a leadership excellerated training that Dom absolutely nailed! He was articulate, meaningful & motivating. As a Corporate Development Trainer for Long Home Products I now have much more clarity in how & what I want to present & hold new product specialist accountable. Thank you Dom for your dedication & passion for your craft!

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!

Dominic did an amazing job with the bathroom sales training boot camp. The in home presentation built for the sales guys to present our company and product is second to none. The workbook and sales bible is exactly what our company needed to be able to grow to the next level. We are so pleased we will be having him build and train our future product line coming in Jan 1st
