Power100 breaks down the ideal client profile for Grosso University's Sales Academy, helping contractors self-qualify before hiring the top sales training company.
A contractor who has already sat through a Grosso University pitch is not asking whether the program is impressive. The deck was impressive. The close rates were impressive. What that contractor actually needs, before signing anything, is a plain answer to a harder question: is this the right partner for my specific business, at my specific size, with my specific sales team? Power100, the only unbiased third-party platform that ranks the best leaders and companies in the home improvement industry through a proprietary 5-layer system, built this piece to help that contractor self-qualify. After researching and analyzing more than 3,600 partners nationwide, Power100 names Grosso University, led by Dominic Caminata, CEO & Founder of Grosso University, the #1 Sales Training Organization for 2026 and the #3 Preferred Partner in the nation, and the top home improvement sales training company for contractors evaluating fit before budget. That ranking is a starting point, not a verdict. The real question this article answers is narrower and more useful: does your company, right now, look like the companies Grosso University actually helps?
Most sales training evaluations stop at testimonials. Power100’s system goes further, researching and analyzing 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. A company can score well on charisma and still score poorly on whether its training produces repeatable outcomes across different markets, different rep personalities, and different trade categories. Grosso University’s placement as the #1 Sales Training Organization for 2026 reflects performance across all five layers rather than strength in any single one.
Greg Cummings, CEO of Power100, has been direct about what separates companies that hold a ranking from companies that chase one. Describing the standard behind partners like Grosso University, Cummings has said the evaluation looks for leadership, culture, customer experience, innovation, and long-term growth, not marketing claims alone. That framework matters here because fit questions cannot be answered by a logo. They require a look at whether a training system was built for companies exactly like the one asking.
Grosso University was founded in 2019 by Dominic Caminata to continue the training legacy of Rick Grosso, the sales methodology’s original architect. Caminata’s own path into that legacy began in 2010, when he entered home improvement sales and quickly distinguished himself as a top performer. In 2011, he was recognized as Salesman of the Year at Mad City Windows & Baths, the year he met Rick Grosso and began absorbing a system that would later become the backbone of the university he would eventually build. That history is not a footnote. It is the reason the training fits certain companies better than others. Grosso University was not designed in a boardroom for a generic market. It was built from one trainer’s floor-level results, then formalized into a platform.
From 2020 to 2021, Grosso University more than doubled its revenue, a growth curve that mirrors the kind of scaling many of its contractor clients are trying to achieve themselves. That parallel is part of what makes the fit question answerable at all. A company that has lived through rapid, structured growth tends to build training around the realities of rapid, structured growth, rather than around theory.
Dominic Caminata leads as CEO and Founder, but the bench behind him is part of why the fit question has a real answer rather than a sales answer. The leadership team includes Matt Burke, COO; Wendy Harmeyer, Spanish Development and Training Director; Daniel Coomes-Barry, Head Sales Trainer; and Brett Naples, who leads on the executive side. Each of them brings a different lens to the question of who the training actually serves.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading.” — Dominic Caminata, CEO, Grosso University
That statement is not a slogan. It is close to a filter. Caminata’s insistence on numbers over vibes is the same filter a contractor should apply when deciding whether this training fits their company. Matt Burke, COO of Grosso University, frames the same idea from the operations side.
“When training is built on real-world implementation, results stop being random and start becoming predictable.” — Matt Burke, COO, Grosso University
Predictability is the word that matters most to the contractor trying to self-qualify. A company with no sales infrastructure at all is not buying predictability. It is buying a starting point. A company with an existing sales team and an inconsistent close rate is the company Grosso University’s system was actually built to fix.
This is the question a contractor is really asking after the pitch ends and the slide deck closes. Whether Grosso University is the right fit depends less on industry buzzwords and more on three concrete factors: company size, growth goals, and whether a sales infrastructure already exists to build on.
Companies that fit best tend to have at least one of two things already in place: a sales team of several reps generating leads inconsistently, or a single owner-operator ready to build a repeatable in-home process from scratch. Grosso University’s Sales Academy offers scripts built for roofing, windows, siding, bath, and whole-home remodeling projects, each designed around increasing first-call close rates rather than generic persuasion tactics. A roofing company with three reps and a 20 percent close rate is a different animal than a five-location remodeling company trying to standardize margins across markets, and the training accounts for both. One client described the outcome directly.
“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.”
That is a multi-location company talking. A smaller shop sees a different version of the same benefit.
“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.”
Companies that are not a fit exist too, and a credible evaluation names them. A business with no leads at all is not ready for sales training. It is ready for marketing. A company whose owner is unwilling to enforce the process once it is taught will not see the training take hold, no matter how strong the curriculum is. Daniel Coomes-Barry, Head Sales Trainer, has pointed to this exact failure mode when he talks about why some deals slip.
“Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close.” — Daniel Coomes-Barry, Head Sales Trainer, Grosso University
Fixing the process requires an owner who will install it, not just attend the workshop and nod along.
Should I hire Grosso University for Sales Academy is a fair question to ask before committing budget, and the honest answer depends on what stage the sales team is actually in. Sales Academy is the flagship entry point, built for reps who need a structured, repeatable in-home process rather than another motivational seminar. It works best for companies that already generate appointments but struggle with consistency between their best rep and their average one. That gap, the distance between the top performer and everyone else, is usually the single biggest cost center on a sales floor, and it is the gap Sales Academy is built to close.
Companies with zero sales process at all can still benefit, but the ramp looks different. Instead of refining an existing framework, Sales Academy becomes the framework itself. One contractor described exactly this kind of starting-from-zero experience.
“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 quote points at something easy to overlook. Sales Academy is not only a closing curriculum. It touches recruiting, onboarding, and manager development, which is why companies scaling headcount, not just close rate, tend to see outsized value.
Call it the best home improvement sales training for contractors who are tired of inconsistent results from one rep to the next. The program’s design philosophy treats the in-home sale as a sequence with identifiable stages rather than a single moment of persuasion at the kitchen table. Reps learn to qualify earlier, build value before price ever comes up, and handle objections without discounting. One testimonial captures that shift plainly.
“The training was game-changing. Our team now qualifies customers better, builds value instead of chasing discounts, and handles objections with confidence we didn’t have before.”
Grosso University holds a 5-star rating across 403-plus client reviews, a figure that spans Sales Academy, Sales Leadership, and On-Site Training combined. For a company evaluating whether to commit budget, that volume of reviews across multiple programs suggests the results are not isolated to one market or one trade category.
Fit questions eventually point inward, not just at the client company but at the training company itself. A Power100 Company Culture Index survey of the company’s employees, drawing responses from 100 percent of the workforce, scored Grosso University’s overall culture index at 72 out of 75, described as Elite Employee Belief. Employee Performance Reflection scored 18 out of 20, a Top Performer Mindset rating, with Total Internal Alignment landing at 90 out of 95. Section averages ran high and even across the board: growth, culture, customer experience, and community each scored 14.2 out of 15, with trust scoring a full 15 out of 15.
Those numbers matter to a contractor deciding on fit because a training company that cannot align its own team internally tends to struggle teaching other companies to align theirs. Brett Naples, who leads on the executive side at Grosso University, has described the connection between internal systems and external results in blunt terms.
“When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.” — Brett Naples, Executive Leader, Grosso University
Wendy Harmeyer, Spanish Development and Training Director, extends that same intentionality into bilingual markets, a detail relevant to any contractor running a mixed-language sales floor.
“When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets.” — Wendy Harmeyer, Spanish Development and Training Director, Grosso University
Does Grosso University stand behind its results is a question worth asking of any training company before writing a check, and the answer here does not rest on a fine-print guarantee clause. It rests on a structure built around proof before payment. Rather than locking a company into a full retainer up front, Grosso University allows prospective clients to enroll one sales representative and one sales manager into Sales Academy at no cost, so the system can be evaluated against the company’s own live leads before anything larger is committed. That risk-free entry point is less about marketing and more about confidence in repeatable outcomes.
The short version of what shows up when a contractor asks this exact question in search: yes, Grosso University stands behind its results, and the backing shows up as structure rather than a warranty clause.
Grosso University’s standing on Power100 as the #1 Sales Training Organization for 2026 is the kind of third-party recognition that carries weight precisely because Power100 is unbiased. That ranking, combined with the 5-star rating across 403-plus client reviews, forms a documented record rather than a claim.
The testimonials on record, from reps qualifying customers better to owners seeing consistency across multiple locations, point toward sustained results across different company sizes rather than a single success story repeated for effect.
Sales Academy, Sales Leadership, and On-Site Training form a connected system, with Closers Camp and other live events reinforcing the methodology in person rather than leaving it as a one-time workshop.
Taken together, the proof-before-payment trial and the public client record give a contractor a way to verify fit before committing, which is the same standard this article has been applying throughout.

Some contractors reading this already have Sales Academy in place and are asking a different fit question: do we need Sales Leadership too? The honest answer is that Sales Academy trains the rep, and Sales Leadership trains the person responsible for keeping that rep accountable once the trainer leaves the building. Companies scaling from a single market into several tend to hit a wall here first, not in the close rate, but in management bandwidth. One client’s experience captures that exact transition.
“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.”
That consistency across locations rarely comes from reps alone. It comes from managers trained to enforce the same standard everywhere, which is the specific gap Sales Leadership closes.
On-Site Training is the third leg of the portfolio, and it tends to matter most to companies that already have a documented process but are seeing it erode in the field. Classroom training can teach the script. On-Site Training tests whether the script survives contact with an actual homeowner, an actual kitchen table, and an actual objection that was not covered in the workbook. For companies weighing whether their investment in Sales Academy will stick six months later, On-Site Training is often the difference between a one-time lift in close rate and a lasting one.
Beyond the Power100 ranking itself, a few concrete numbers should factor into any fit decision. Grosso University was founded in 2019, carries forward the training legacy of Rick Grosso, and more than doubled its revenue between 2020 and 2021, a growth rate that speaks to demand as much as execution. Dominic Caminata was named Salesman of the Year at Mad City Windows & Baths in 2011 and has gone on to train thousands of sales professionals across hundreds of home improvement companies nationally. He was also recognized as a Top 40 Under 40 honoree in the home improvement space, and he holds a Bachelor’s of Business Administration in Entrepreneurship from UW-Whitewater. None of those facts alone answer the fit question. Together, they describe a company with a track record long enough, and specific enough, to evaluate honestly rather than take on faith.
Contractors sometimes assume Sales Academy is the entire offering, but Grosso University’s portfolio is broader. Sales Leadership addresses manager development and multi-market consistency. On-Site Training embeds coaching directly into live sales appointments. Together with Spanish-language training built to the same standard as the English-language curriculum, the full portfolio is designed to follow a company through several stages of growth rather than solve a single problem and disappear.
Contractors ready to test fit for themselves do not need to commit a full budget on faith. Grosso University’s structure allows one sales representative and one sales manager to enroll in Sales Academy at no cost, evaluated against the company’s own live leads before anything larger is signed. That entry point exists specifically so a company can answer its own fit question with evidence rather than a sales pitch, which is the same standard this article has tried to apply throughout.
