Best training in the industry, Dan’s Real World Experience and down to earth, easy to relate to delivery transforms a “mandatory” training into one I looked forward to each day!

Dan is incredibly motivating talented. His 11 step course changed the way I look at sales, negotiation, and human interaction more generally. I could not recommend this company enough! If you are serious about becoming the best version of yourself, take the course.

Training with Dan was amazing. He is so knowledgeable and has a plethora of information. He truly inspired me to go out and close, close, close. This is the best sales training course, I have ever attended!

Dan was excellent! It was thorough and all the details were essential! I am confident I will be infinitely better at my Job.

Unreal absolutely outstanding training if you wanna learn to make over quarter mil a year get with this guy!

Dan is the man!! Totally worthy and worthwhile!

Phenomenal training class, Dominic Has completely refreshed my mind of what the idea of sales is and I’m excited to be able to take what I’ve learned from him and apply it to what I do every day

Extremely knowledgeable. Honestly, gave a boost to the whole room when he walked in. Golden opportunity to learn from Dominic. Real eye opener. Thank you brother. Sincerely.

Great training class!!

As someone who is newer to first call close in-home sales, Dan was a wealth of knowledge who broke down concepts in a really digestible way. Really cool down to earth guy who seems to genuinely care about equipping salespeople with the tools to be successful

Incredible training with Grosso University! Whether you are a seasoned veteran getting a refresher or someone that is new to the industry, Grosso University's training helps shape you into the best sales rep possible. Very thorough and informational and made me feel comfortable going into my new role!

Dan’s training was very relatable, personable, down to earth and actionable. It did not feel like other training classes.
