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!

They said over the next two weeks you will work harder than you ever have before and I honestly rolled my eyes to myself and thought here goes the normal training lingo… but 5 minutes later my eyes were opened to the most in depth hands on training experience I’ve ever experienced in my professional career, well exceeding and upper management what I thought then to be high level training. However the level of skill they possess makes you feel embraced and in control of all projects with out even realizing. Can not imagine what kind of career I would have spent wasting time attempting this job with out this quality training presented these last two weeks. Beyond grateful for being apart of this!

Well trained class and very thorough!! I’ve personally been through many different training classes and schools and this is by far the best I have ever attended. Not every trainer I’ve dealt with has even spent a day out in the field as far as what they are training on but these guys have started exactly where I am and they truly know what they are talking about! What I love the most is that they don’t only train you on your job but they focus on making you a better person and their training pertains to your everyday life. Great job guys!!!

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!!!

Nothing Works Like This

I'm at my 6-week mark, and you never know what to expect. Being able to ask questions and interact live is extremely helpful. I knew it was good, but I didn't know it was this good. After 15 years in the Marine Corps and attending 10 sales schools, I’ve never seen anything like this.

Effectively Go Up Against Competition

This event was one of the most engaging I’ve attended in a long time, keeping me focused from start to finish. I took plenty of valuable notes that I can’t wait to bring to our sales meeting on Monday. The content was structured with practical, easy-to-implement strategies that fit seamlessly into our daily practices.

Best Sales Training Seminar

My favorite part was focusing on team and personal goals while using the right tools to succeed. I’ve attended other industry sales seminars, but this was by far the best sales training seminar I’ve been to. Dominic’s in-depth research on our products made the training even more informative and impactful.
