Great job, great information if you’re a veteran salesperson then you might want to unlearn your bad habits and Learn something new if you want to earn 6 figures yearly!!

We had the pleasure of having Dominic in to train our leadership team. He was extremely well prepared and delivered a spot on and relevant training that I am sure will help our organizations be more successful immediately. Thanks for the time Dom! Looking forward to the next one.

Grosso University is the real deal. I come from restoration roofing sales and did very well clearing 1 million in net sales every year for 3 years straight. The company I currently work for pivoted from a restoring roofing model into a retail sales model. I was tasked with the responsibility to build and train a retail one stop sales team for roofing, siding, windows, & showers. I quickly realized that I sold all my previous jobs on knowledge, authenticity, and charm but no real system was in place. How do you expect to train a one stop sales team if your sales manager can’t even right out a proven sales system. Well good news, they don’t have to. After months of looking I finally landed on Grosso University. I knew after meeting with Dominic & his team they were the ones I wanted to work with. Once the decision was made I put in maximum effort to learn this system where i could posses the skill to train it and that’s what I did. This system along with intentional effort to learn / implement allowed me to build a team from 3 million to 10.1 million in three years. These are good people and if you’re willing to learn you will possess a life changing skill that keeps on giving.

I already had some success with one visit closing prior to attending the Grosso University. But the information that I’ve learned in the last two weeks has taken me to the next level! Dan Coomesbarry is an excellent and very knowledgeable instructor. Regardless if you’re experienced or have never been in sales before this training will definitely have you ready to concur the industry. The class was very informative while also being fun and not overwhelming. I will definitely still be login in to the trainings although I’m officially done with the course.

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.

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.

Absolutely worth every penny! I wish I had this training when I first started in sales. It’s a lifetime of sales experience in just 2 weeks, but worth the challenge. No pain no gain!
