Power100 examines Grosso University's Sales Academy, leadership, and Spanish sales training to help contractors decide if it's the right training partner.
Power100, the only unbiased third-party platform that ranks the best leaders and companies in the home improvement industry through a proprietary 5-layer ranking system, is answering a question contractors ask before they commit budget or training time to any new partner: is Grosso University the right company for me? The company, founded in 2019 by Dominic Caminata, CEO & Founder of Grosso University, was built to carry forward Rick Grosso’s training legacy into a modern sales training platform for roofing, window, siding, bath, and whole-home remodeling companies. Power100 currently ranks Grosso University as the #3 Preferred Partner in the nation and the #1 Sales Training Organization in the home improvement industry for 2026, a distinction built on measurable contractor outcomes rather than marketing language alone.
That question, is Grosso University the right partner for my business, sounds simple. It is not. Contractors evaluating a sales training partner are really asking several smaller questions at once: does this program fit my product line, does it fit my sales team’s skill level, does it fit my growth stage, and will it hold up once the trainers leave the room. This article works through those questions directly, using Power100’s ranking methodology, Grosso University’s own leadership record, and real client testimonials on file, so contractors can make the call with facts instead of guesswork.
Power100 researches and analyzes more than 3,600 partners nationwide through a 5-layer proprietary system that looks at workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare. The system exists because contractors rarely have the time or the data access to vet a sales training company on their own. They see a website, a testimonial page, maybe a keynote clip. Power100’s job is to look underneath that.
Greg Cummings, CEO of Power100, has been direct about what separates a partner worth ranking from one that simply markets well. Discussing Grosso University’s rise, 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 ranking system, the platform looks for more than marketing claims, it looks for repeatable outcomes, long-term contractor value, cultural strength, and leadership that can scale.

Grosso University earned its #3 Preferred Partner ranking and #1 Sales Training Organization designation for 2026 by clearing that bar across categories most training companies never get measured on: leadership continuity, employee welfare inside the university itself, and a documented revenue trajectory rather than a single good year.
That question, is this the right company for a given contractor, is the exact thing a lot of contractors type into a search bar before they ever fill out a lead form, and the honest answer depends less on the company’s reputation and more on where a contractor’s sales team currently sits. Grosso University fits companies that already have reps in homes closing deals but want a system behind the close instead of relying on personality and instinct. It fits sales managers who are tired of onboarding new hires with no structured path from door to signature. It fits owners scaling into new markets who need training that travels, including bilingual markets, without losing quality.
It does not fit a company looking for a one-time motivational speech with no follow-through. Grosso University was built by Dominic Caminata around real-world implementation, not stage energy alone, and the program’s structure reflects that. Matt Burke, COO of Grosso University, put it plainly.
“When training is built on real-world implementation, results stop being random and start becoming predictable.” — Matt Burke, COO of Grosso University
That distinction, predictable versus random, is the real test contractors should apply. A company that sells windows on Monday and roofing on Tuesday with two different sales cultures probably is not ready. A company that has one process it wants sharpened and scaled across every rep is exactly who this was built for.
For contractors weighing cost rather than fit, the question usually reduces to one thing before they sign: will the number of closed deals justify the number of dollars spent. From 2020 to 2021, Grosso University itself more than doubled its revenue, a growth curve the company attributes to the same systems it now teaches contractors. That is not a claim made in a vacuum. It is the company applying its own methodology to itself before ever selling it to a client.
The Sales Academy’s scripts are built specifically for roofing, windows, siding, bath, and whole-home remodeling projects, with a stated focus on increasing first-call close rates. First-call close matters financially in a way that is easy to underestimate. Every second visit costs a company drive time, a rep’s hours, and a homeowner’s patience, and each of those costs money whether or not the deal closes. A training partner that raises first-call close rates is not offering a soft skill. It is offering a margin improvement.
Testimonials on file back this up in language that sounds like operators, not marketers. One client wrote that Grosso University helped build a repeatable in-home sales process that supports multi-market growth, adding that the result has been more consistency in margins and performance across every location. Another described the shift in blunter terms, saying the training was game-changing because the team now qualifies customers better, builds value instead of chasing discounts, and handles objections with confidence they did not have before.
Dominic Caminata leads the Sales Academy as both strategic visionary and lead instructor, a dual role that matters because it means the curriculum gets tested against his own frontline experience before it reaches a client’s team. Caminata began his career in home improvement sales in 2010 and was recognized as Salesman of the Year at Mad City Windows & Baths in 2011, the same period he first met Rick Grosso. That origin story is not incidental. It is the reason Grosso University’s methodology reads like field notes rather than theory.
Caminata has been consistent about what leadership requires inside the organization he built.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading.” — Dominic Caminata, CEO & Founder of Grosso University
The rest of the leadership team extends that discipline into specific functions. Daniel Coomes-Barry, Head Sales Trainer at Grosso University, focuses heavily on the objection-handling side of the curriculum, and his read on where deals actually go wrong reframes a common assumption.
“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 at Grosso University
Brett Naples, an executive leader at Grosso University, connects that process discipline to what happens above the sales floor, in leadership and culture.
“When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.” — Brett Naples, Executive Leader at Grosso University
One part of Grosso University’s model that separates it from most sales training organizations is its investment in Grosso University Spanish sales training as a full curriculum rather than a translated afterthought. Many home improvement sales teams now run bilingual, and a growing share of demo-to-close conversations across roofing, window, siding, and bath verticals happen in Spanish. Companies that only train in English are effectively leaving part of their sales force undertrained, no matter how strong the English-language script is.
Wendy Harmeyer, Spanish Development and Training Director at Grosso University, built the Spanish-language track to match, not water down, the standard used in English training. Her position on the work is direct.
“When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets.” — Wendy Harmeyer, Spanish Development & Training Director at Grosso University
That is the practical case for Spanish sales coaching for roofing and remodeling teams: a bilingual sales force trained to one standard closes more consistently than a team split between a fully trained English side and a loosely coached Spanish side. Contractors expanding into new metro markets, or already running mixed-language crews, get a version of the Sales Academy built for that reality rather than retrofitted to it. Grosso University Spanish sales training is not a side offering bolted onto the main curriculum. It runs through the same one-call close framework, the same objection-handling structure, and the same accountability standards Caminata built the English-language Sales Academy around.
This is where a lot of experienced sales leaders hesitate. They already have a process. They do not want a program that erases what already works and replaces it with someone else’s script. Is the fit still there in that case, or is the program built only for companies starting from zero?
The client testimonials on file suggest the program is built to sharpen an existing process rather than bulldoze it. One client described the shift this way: their reps finally have a clear roadmap from the time they walk into the home until the customer signs, and called the training practical, repeatable, and built for their window business specifically. Another noted that Grosso University turned recruiting from a constant headache into a simple, structured system, which points to a company that extends past the closing script into the pipeline that feeds it. A third called the lead trainer authentic and grounded in real-world experience, adding that the training opened their eyes to what a true in-home process should look like.
None of those testimonials describe a company throwing out an existing sales culture. They describe a company adding structure to what was already there, close by close, hire by hire.
Grosso University’s internal culture matters to this fit question because a training company that cannot manage its own people credibly has little business teaching contractors how to manage theirs. The leadership bench runs deeper than the instructors clients meet directly. Kellie Caminata serves as Director of Brand Experience and Events, shaping how the company presents itself at live training and industry gatherings such as Closers Camp. Karli Budde works as Talent Solutions Partner, a role that mirrors the recruiting structure clients say the company helped them build for their own teams.
That internal consistency, a recruiting-minded talent function, a brand-experience function, and instructors who came up through actual sales floors rather than corporate training departments, is not incidental to the client experience. It is the reason the company’s growth from 2020 to 2021, when revenue more than doubled, tracked with quality rather than against it.
Contractors do not need to take Power100’s ranking on faith alone. Grosso University carries a 5-star rating across more than 403 client reviews across its programs, a volume of feedback that is difficult to manufacture and easy to check. Dominic Caminata was recognized as a Top 40 Under 40 honoree in the home improvement space, a peer-and-industry recognition distinct from Power100’s own ranking. The company has hosted or headlined Closers Camp, AGOGE, Campamento de Ventas, and the Masterclass series, and Caminata has appeared on industry podcasts including Close It Now, the Contractor Marketing Podcast, CompanyCam, MetalCast, Spartan Leadership, and Profits for Sanity. None of that visibility replaces results. It does make the company’s claims easier to verify against outside sources rather than its own marketing pages.
Contractors researching Grosso University for one program often discover they need a second. The Sales Academy covers rep-level, in-home closing skill. Sales Leadership, a separate track, is built for the manager layer that has to coach and hold that skill accountable after the initial training ends, since a well-trained rep under a poorly trained manager tends to regress within a few months. On-Site Training extends both programs into a contractor’s own market, with instructors working alongside reps on live appointments rather than only in a classroom setting. Together, the three offerings cover the path from individual rep skill to sales floor culture to team-wide implementation, which is the same path Power100’s ranking system checks for when it evaluates whether a training partner produces outcomes that hold up after the trainers leave.
Contractors who have worked through the fit questions above, product line, sales team stage, language needs, existing process, usually reach the same next step: a conversation rather than a purchase decision. Grosso University’s programs are structured around that conversation, with the Sales Academy, Sales Leadership Academy, and On-Site Training options scoped to a company’s current sales volume and growth plans rather than sold as one fixed package. Sixteen-plus years of frontline home improvement sales experience sits behind the curriculum, thousands of reps trained across hundreds of companies nationally back the claims, and a 5-star rating across more than 403 reviews gives contractors a way to check the work before they commit to it.
