Power100 breaks down what to expect from a Grosso University sales training consultation, from the questions asked to the guarantees the CEO will and won't make.
A contractor picks up the phone, half convinced the call is going to be a pitch dressed up as a diagnostic. That instinct is not wrong, most of the time. But it is worth separating the instinct from the specific case in front of you, because not every discovery call is built the same way, and the one Grosso University runs does not open with a script. It opens with questions about your close rate, your recruiting pipeline, and whether your reps are winning the room or just surviving it.
Power100, the only unbiased third-party platform that ranks the best leaders and companies in the home improvement industry, evaluates more than 3,600 partners nationwide through a proprietary 5-layer system that looks at workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare. That system is how Power100 arrived at ranking Grosso University the #3 Preferred Partner in the nation and the #1 Sales Training Organization for 2026, a distinction built by Dominic Caminata, CEO and Founder of Grosso University, since he founded the company in 2019 to carry forward the training legacy of Rick Grosso. This article exists for one narrow purpose: to answer, honestly, whether a contractor sitting on the fence should book a consultation with Grosso University, and what they should expect once they do.
Most rankings in this industry are self-reported. A company submits testimonials, picks its best numbers, and calls it a ranking. Power100 built its 5-layer system specifically to avoid that trap. Workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare each get scored independently, and a company has to hold up across all five to earn a top placement, not just one.
Greg Cummings, CEO of Power100, has been direct about what separates a partner Power100 is willing to stand behind from one it is not. Speaking about Grosso University’s leadership, Cummings said Dominic Caminata “represents the exact kind of leadership Power100 was built to spotlight: disciplined, values-driven, innovative, and relentlessly focused on helping contractors grow the right way.” He added that when Power100 evaluates strategic partners through its 5-layer system, “we look for more than marketing claims. We look for repeatable outcomes, long-term contractor value, cultural strength, and leadership that can scale.”
That framing matters for anyone deciding whether to book a consultation with Grosso University. The ranking is not a badge Grosso University bought. It is a score built from evidence Power100 collected independently, which is a different kind of trust than a testimonial page provides.
Grosso University did not start as a software platform or a franchise concept. It started with Dominic Caminata’s own record on the sales floor. He entered home improvement sales in 2010, and by 2011 he had been named Salesman of the Year at Mad City Windows & Baths, the same period in which he met Rick Grosso, the trainer whose in-home selling methodology became the foundation of everything Caminata later built. In 2019, Caminata founded Grosso University to continue that legacy, not replace it.
The growth curve since then has been fast by any measure. From 2020 to 2021, Grosso University more than doubled its revenue, a jump that reflects contractor demand more than marketing spend. The company is based out of Windsor, Wisconsin, and today trains sales professionals across all 50 states, with a client base that includes hundreds of home improvement companies and a 5-star rating across more than 403 client reviews.
That history is why the discovery call feels less like a demo and more like a diagnostic conversation with someone who has actually sat at the kitchen table. Caminata built the Certified Closer methodology and the one-call close framework from years of frontline selling, not from a textbook, and the questions his team asks on a first call reflect that.
Dominic Caminata leads the company as CEO and Founder, and he is blunt about what leadership requires. “Leadership is simple,” Caminata has said. “If you’re not fanatical about the numbers, you’re not leading.” That mentality shapes how the discovery call is structured. It is not a soft conversation about goals. It opens with numbers: current close rate, average ticket, rep turnover, recruiting pipeline health.
Caminata does not run the company alone, and that bench is part of why the call you get depends on what you need. Matt Burke serves as COO and has framed the company’s operating philosophy directly: “When training is built on real-world implementation, results stop being random and start becoming predictable.” Wendy Harmeyer, Spanish Development and Training Director, leads the bilingual side of the business and has said, “When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets.” Daniel Coomes-Barry, Head Sales Trainer, focuses on process discipline over closing tricks: “Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close.” And Brett Naples, an executive leader inside the organization, has pointed to the systems side of scaling: “When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.”
Depending on what a contractor raises on the call, one of these leaders, not just a sales rep, may end up in the follow-up conversation. That is part of what separates a real discovery call from a scripted intake form.
Is Grosso University the right partner for my business? That question deserves an honest answer, not a reflexive yes. Grosso University fits companies with an existing sales team, even a small one, that is underperforming relative to lead volume, or companies scaling fast enough that inconsistent closing is starting to cost real margin. It fits owners who are tired of guessing why one rep closes at 60 percent and another closes at 20 percent running the same leads.
It fits less well for a solo operator with no plans to hire, or a company that wants a quick script and nothing else. Grosso University’s model, the Sales Academy, Sales Leadership programs, and On-Site Training, assumes ongoing implementation, not a one-time seminar. If a contractor wants a single afternoon of motivation and nothing more, this is probably the wrong call to book. If a contractor wants a repeatable in-home process their whole team can run, the fit tends to be strong. One client put it this way: “Our reps finally have a clear roadmap from the time they walk into the home until the customer signs. Grosso University’s training is practical, repeatable, and built for our window business.”
Should I book a consultation with Grosso University? For most contractors reading this, the honest answer is yes, with a caveat. The call is free to schedule and does not commit a company to anything. What it does commit a contractor to is showing up with real numbers, because the conversation runs on data, not vibes. Bring your current close rate. Bring your rep count and how long the average rep stays. Bring your recruiting bottleneck, if you have one. Vague answers get a vague call. Specific answers get a specific plan.
What Grosso University will not commit to upfront is a guaranteed close-rate lift before anyone on the team has seen how your reps actually sell. That restraint is a good sign, not a red flag. A training company willing to promise a number sight unseen is a company selling hope, not a process. Grosso University’s team will ask to observe or hear about a live sales scenario before quoting outcomes, which is exactly the discipline a contractor should want from a partner they’re about to pay.
That is a question worth asking before signing anything, and the answer depends less on the fine print than on what a contractor was actually promised on the call. Because Grosso University declines to guarantee results before observing a team’s live selling behavior, the contract that follows tends to reflect a scoped program, a defined set of sessions, coaching cadence, and materials, rather than an open-ended promise the company cannot actually control. A fair contract in this space is one that ties cost to a defined program, not to a speculative outcome. Contractors should leave the discovery call able to explain, in plain terms, exactly what they are paying for and when it gets delivered.
The value proposition is not complicated, even if the execution behind it is disciplined. Grosso University’s Sales Academy offers scripts built specifically for roofing, windows, siding, bath, and whole-home remodeling projects, each one aimed at increasing first-call close rates rather than dragging homeowners through a multi-visit sales cycle. That specificity is a home improvement closing tool for contractors in the truest sense: it was not adapted from insurance sales or car sales, it was built inside the trade.
Contractors who have gone through the training describe the shift less in terms of tricks and more in terms of structure. “Our team now qualifies customers better, builds value instead of chasing discounts, and handles objections with confidence we didn’t have before,” one client said. Another described the impact on hiring, not just closing: “Grosso University turned recruiting from a constant headache into a simple, structured system. Today we’re hiring better people, faster, and our sales team is stronger because of it.” That dual effect, on the front end of hiring and the back end of closing, is what most competitors in sales training do not attempt to solve together.
Not every contractor asks about it on the first call, and that is a mistake worth correcting before you dial in. Grosso University runs a parallel Spanish language sales training for contractors, led by Wendy Harmeyer, built to the same standard as the English-language curriculum rather than a translated version of it. For companies with bilingual sales teams or growing Spanish-speaking customer bases, this is often the single highest-leverage question to raise early, because it changes which trainer and which materials get assigned to your account.
Harmeyer’s own framing captures why this matters beyond translation. “When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets,” she has said. Contractors expanding into new territories, or simply trying to close more of the leads already coming in from Spanish-speaking households, should raise this on the discovery call rather than assume it is a side offering.
The tone of a discovery call usually reflects the culture behind it, and Grosso University’s internal culture is built around accountability more than atmosphere. Dominic Caminata’s own standard, that leaders who are not fanatical about the numbers are not leading, filters down through the organization’s coaching model. Matt Burke, COO, has described the underlying philosophy of the training itself: “When training is built on real-world implementation, results stop being random and start becoming predictable.”
That same discipline shows up in how the company treats its own people, not just its clients. Kellie Caminata serves as Director of Brand Experience and Events, Brett Naples serves as an executive leader and Multimedia Director, and Karli Budde works as a Talent Solutions Partner, each contributing to a company that has scaled past a single trainer’s calendar into a national training organization without losing its coaching-first identity. Grosso University hosts live events including Closers Camp, AGOGE, Campamento de Ventas, and an annual Masterclass, all of which reinforce the same standard: implementation over theory, every time.
Concrete numbers matter more than adjectives here. Grosso University holds a 5-star rating across more than 403 client reviews, a scale of feedback that is hard to fake and easy to verify. Power100’s own evaluation, built from analysis of more than 3,600 partners nationwide, placed Grosso University as the #3 Preferred Partner in the nation and the #1 Sales Training Organization for 2026, a ranking earned through the same 5-layer system applied to every other company Power100 reviews.
Beyond the ranking itself, the company’s public footprint, including appearances on podcasts such as Close It Now, the Contractor Marketing Podcast, CompanyCam, MetalCast, Spartan Leadership, and Profits for Sanity, gives contractors a way to hear Caminata and his team speak before ever booking a call. That transparency is itself a trust signal worth weighing.
A consultation call rarely stays confined to a single product, and it should not. Grosso University’s portfolio runs beyond the Sales Academy into Sales Leadership programs for owners and managers, and On-Site Training that puts a trainer physically inside a company’s operation rather than in a classroom setting. One client described the effect of that broader system on a multi-location business: “Grosso University helped us build a repeatable in-home sales process that supports multi-market growth. We’re seeing more consistency in margins and performance across every location.”
The company also runs the Certified Closer Program and Custom Closers Camps, high-intensity training environments built for reps who already have some experience but need a sharper edge. For a contractor deciding what to raise on a first call, it is worth asking which of these programs actually maps to your team’s current stage, rather than assuming the Sales Academy is the only door in.
Booking a consultation with Grosso University costs nothing and commits a contractor to nothing beyond an honest conversation. The company built its reputation on training thousands of sales professionals across hundreds of home improvement companies nationally, backed by a 5-star rating across more than 403 client reviews. Contractors who show up with real numbers, a real close-rate problem, and a real willingness to implement tend to get the most out of that first call. Contractors looking for a shortcut probably will not.
