Dan is the man. This training was by far the best training I’ve been through and I’ve been through multiple training programs before. 10/10…. correction 11/10.

What can I say? I've never enjoyed school, but Dan and Dominic have me pretty disappointed to have passed this class and moved on. It was faaaaantastic. I'm beyond grateful that my company was willing to invest in my training, and Grosso University was THE training for me. Thank you guys so much.

Dan is the man. Grosso has helped me take my sales skills to the next level. The best training you could ever get to become an elite sales rep!!

Coming into the home improvement sales industry with no knowledge whatsoever, after two weeks working with Dan Coomes-Barry, i am so surprised at how much I’ve learned. Grosso University’s 11 Step Breakdown is rigorous to say the least, and I’m not joking when I say that I’ve learned more here than I have in a semester long business class. My entire mindset surrounding sales has changed to set me up for success in the field. While the course is just two weeks long, I have up to date and evolving video resources available to me whenever I need them, as well as the invaluable peace of mind knowing that Dan is a going to be there to answer any questions I have down the road. This is an investment that is 100% worth it, and with the correct application and a positive mindset, I can confidently say that it will change your life for the better. Put in the work, you won’t regret it.

Dan was fantastic, he walked through this training with grace and really took the time to make sure he answered any and all questions. Very informative.

WOW!!! Grosso University!!! Where have you been all of my life! This is amazing program that teaches you how to better understand your customer on front of you and how to deliver your information in a way that if you do it right, you close in my case, 6 of of 10! Daniel made this last 2 week fun and very informative. I really enjoy everything. And after putting in place some of this new tactics, I was able to close at 60% this last week!! Thank you Grasso University!!!

In depth training! Dan was great!

Lakota Tidd

Had a great experience. My goal was to come here and learn 1-2 great things to take back to our company Top Home Improvements. After all the speakers I am shocked on how much I have learned. I’m going to take at least 30 great ideas back home and with that, going to make our company a more profitable place. Great culture, great networking, great event. I’m ready to hustle!

Dan was awesome and very engaging. The program was precisely laid out for an easy transition into one time closing. Thank you!

Grosso University is an excellent training platform for anyone who is looking to master their craft. I worked for Ashley Furniture for 6 years and we used Cardone University for sales training. The two platforms share some similarities but I felt that the coach for Grosso, Dominic Caminata, was much more effective than Grant Cardone for sales training.

very collaborative, Daniel and Corwin combine their years of experience and teach in a very understanding way. They make it fun, and install confidence in a great way! I will be using this for the rest of my life!

I work for Windows Plus in Louisville and I was apart of a sales boot camp done by Corwin Crockett. The amount of knowledge I learned on how to sell and talk to people was astronomical. I personally liked how Corwin taught me how to sell when I’m not at the most favorable appointments. This has already began to help me at my sales appointments.
