Our entire sales team just went through the two week training program and we are already seeing results in our closing ratio. Dan is an excellent trainer and much to my surprise I have really enjoyed the class. I recommend Grosso University to other home improvement companies except for our competitors. 🤣
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!
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.
Great training! Dan is a wonderful trainer. I truly feel that this training is going to transform our sales org in 2025!
AMAZING sales training from Dominic and Dan! Highly recommend!
Great course learned more in two weeks than I have in two years of sales.
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.
Dan is an excellent instructor. Took every opportunity to be thorough and gives the nitty gritty details of in home sales. Although the class size was a bit larger, we still only saw a few consistent individuals contributing to the class. It was informative and followed their step by step process to a tee.
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.
Amazing window demonstration these guys know their stuff. Cannot say enough about these guys !
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 and everyone at Grosso university have helped me grow as a salesperson by providing me with the tools I need to succeed in the customers home. With Dans experience, and the knowledge from their guide, I can confidently say I have a better understanding of sales after the two week course.
Invest in yourself! If you're truly serious about getting better at sales, take this course. The techniques learned can be applied across several industries. You will get the tools to succeed, the rest is up to you.
Unbelievable experience. Dan is so knowledgeable on everything and one of the coolest teachers I’ve ever meet. Definitely worth doing and had a great time learning from Dan.
