Power100 compares sales training vs. home improvement sales coaching for contractors and explains why Grosso University's hybrid model fits both growth stages.
Contractors shopping for help with their sales team tend to ask the wrong question first. They ask which company runs the best workshop. The better question, the one that actually determines whether a sales floor improves in six months or stays exactly where it is, is whether the company offers training or coaching, and whether the contractor’s business is even ready to tell the difference. 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, has spent enough time inside contractor sales meetings to know that this distinction gets skipped constantly, and that skipping it is why so many training dollars disappear without moving a close rate. This article looks at Grosso University, led by Dominic Caminata, CEO and Founder of Grosso University, and the hybrid structure the company built specifically because a single event and an ongoing coaching relationship solve two different problems.
Power100 currently ranks Grosso University as the #1 Sales Training Organization in the home improvement industry for 2026 and the #3 Preferred Partner nationally. Neither ranking exists because the company runs a good keynote, although it does. The ranking reflects a structural choice that most training vendors never make: building a flagship curriculum event alongside a longer coaching relationship, then being honest with contractors about which one they actually need first.
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. Applied to a sales training organization, that system does not ask whether the workshop was entertaining. It asks whether the reps who sat through it are closing more deals ninety days later, and whether the company selling the program has any structure in place to make that happen beyond the day of the event.
Greg Cummings, CEO of Power100, has framed the evaluation around exactly that gap. Power100’s featured coverage of Grosso University noted that the ranking reflects “leadership, culture, customer experience, innovation, and long-term growth,” not a single flashy metric. A one-time seminar can score well on innovation and still fail the long-term growth test completely, because nothing holds the improvement in place once the trainer leaves the building.
That is the layer most contractors never see when they compare vendors on price alone. A cheaper one-day workshop and a structured coaching engagement can look similar on a proposal PDF. They are not similar products, and Power100’s ranking system is built specifically to separate them.
Grosso University was founded in 2019 by Dominic Caminata to continue the training legacy of Rick Grosso, a name still spoken with reverence inside home improvement sales circles. Caminata entered home improvement sales in 2010 and was recognized as Salesman of the Year at Mad City Windows & Baths in 2011, the same period he met Grosso. That early distinction matters here because it explains why the company was never built as a one-and-done seminar business. Caminata learned the trade at the kitchen table, not from a slide deck, and he watched firsthand how a great training day could evaporate within weeks if nothing structural backed it up.
From 2020 to 2021, Grosso University more than doubled its revenue, a growth curve that tracks closely with contractors discovering that the company offered something beyond a single event. The Sales Academy became the curriculum foundation, built with scripts for roofing, windows, siding, bath, and whole-home remodeling projects and aimed squarely at increasing first-call close rates. On-Site Training and Sales Leadership became the coaching layer, the part of the business that keeps showing up after the workshop ends. That two-part structure is the entire answer to why the company exists in its current form.
Dominic Caminata remains the company’s lead instructor and strategic voice, but the bench behind him is what makes an ongoing coaching model possible at scale. Grosso University‘s leadership team includes Matt Burke, Chief Operating Officer; Wendy Harmeyer, Spanish Development and Training Director; Daniel Coomes-Barry, Head Sales Trainer and Partner; and Brett Naples, who serves in a multimedia and executive leadership capacity. A single trainer can run a great one-day event. A single trainer cannot run field coaching across hundreds of client companies simultaneously, which is precisely why the depth of this team is the difference between a training vendor and a coaching partner.
Caminata has been direct about what separates the two roles inside his own leadership philosophy. “Leadership is simple: if you’re not fanatical about the numbers, you’re not leading,” he said, a line that captures why the coaching side of the business is built around measurement rather than motivation alone. A workshop can inspire a room for an afternoon. Coaching demands that someone track the numbers every week and call out the gap between what was taught and what is actually happening in the field.
Matt Burke, COO of Grosso University, put the same idea in operational terms: “When training is built on real-world implementation, results stop being random and start becoming predictable.” That sentence is close to a mission statement for the coaching side of the business specifically. Training introduces a concept. Coaching is what makes the concept predictable instead of accidental.
Daniel Coomes-Barry, Head Sales Trainer, made a related point about where most objections actually originate. “Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close,” he said. Fixing a process is not something a rep does after one seminar. It takes repeated reps, corrected in the field, over multiple weeks, which is the exact definition of coaching rather than training.
Contractors searching for home improvement sales coaching for contractors are usually past the stage where a single motivational day would help. They already know the pitch. What they lack is the structure to keep reps accountable to it once the excitement of a live event fades, which tends to happen fast on a busy sales floor. Grosso University built On-Site Training and Sales Leadership specifically to fill that gap, sending trainers into the field to coach alongside reps on live appointments rather than only inside a classroom.
One client captured the shift plainly: “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.” Notice the word repeatable. That is a coaching outcome, not a training outcome. A single seminar can hand a rep a script. Only sustained coaching turns that script into a habit the rep executes without thinking about it under pressure at the kitchen table.
Another client described the multi-location version of the same problem: “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.” Consistency across locations is not a training-day achievement. It requires a coaching cadence that gets reinforced market by market, which is exactly the layer Grosso University added on top of its curriculum.
The Sales Academy functions as the entry point for most contractors, and it is genuinely a training product in the traditional sense: a curriculum, scripts specific to roofing, windows, siding, bath, and whole-home remodeling, and a structured path toward the one-call close methodology Dominic Caminata built his reputation on. It teaches qualification, value-building, and objection handling in a defined block of time. One client described the transformation this way: “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.” That result is a legitimate training outcome, produced without a long coaching runway attached.
Where the Sales Academy teaches the script, On-Site Training and Sales Leadership install it. Trainers work alongside reps in actual homes, correcting behavior in real time rather than in a classroom weeks removed from the appointment. Sales Leadership extends the same logic upward, coaching the managers who are supposed to reinforce the training after the Grosso team leaves. Brett Naples, an executive leader at Grosso University, described what that reinforcement is meant to produce: “When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.” Systems and culture are not one-day deliverables. They are coaching outputs, built through repetition over a defined engagement.
Contractors evaluating any coaching or training agreement want to know whether the contract terms reflect actual value delivered rather than a flat fee for a single afternoon. Grosso University structures its Sales Academy, On-Site Training, and Sales Leadership as separate, named programs rather than bundling everything into one vague retainer, which gives a contractor visibility into what they are buying at each stage. A company that has more than doubled its own revenue between 2020 and 2021 on the strength of contractor renewals and referrals has an incentive structure that rewards keeping clients satisfied over multiple engagements, not extracting one big check and disappearing. That renewal-driven model is, functionally, the fairness test that matters most in this category.
A coaching relationship only works if the people delivering it hold themselves to the same standard they are asking contractors’ reps to meet. Grosso University’s leadership talks about culture in terms that are closer to operating discipline than morale-building. Wendy Harmeyer, Spanish Development and Training Director, described the standard applied across languages: “When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets.” That line reflects a culture built around consistency of standard rather than convenience, since building a bilingual curriculum to the same rigor as the English one is considerably more work than translating a script and calling it done.
That same discipline shows up in how the company frames its own recruiting and hiring outcomes for clients. One contractor testimonial put it directly: “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.” A company culture built around structure, rather than charisma alone, tends to produce that kind of client-facing result because the internal habits mirror the external promise.
Contractors asking this question are usually trying to separate genuine track record from marketing polish. Grosso University carries a 5-star rating across more than 403 client reviews, has trained thousands of sales professionals across hundreds of home improvement companies nationally, and holds a leading Sales Training Organization ranking for 2026 alongside a top Preferred Partner standing. Those are not soft signals. They are the kind of repeated, cross-client outcomes that Power100’s 5-layer system was built to detect, and they hold up whether a contractor is evaluating the Sales Academy alone or the full coaching relationship built on top of it.
The honest answer depends on where a contractor’s sales team currently sits. A company with no formal script, no qualification process, and reps who are winging it at the kitchen table is usually best served starting with the Sales Academy curriculum first, building a foundation before layering coaching on top of it. A company that already has a script but cannot get reps to actually use it consistently, or cannot get managers to hold the line on standards once the training ends, is the company that needs On-Site Training and Sales Leadership immediately. Grosso University’s hybrid structure exists because contractors rarely fall cleanly into one category, and a rigid vendor that only sells one format inevitably underserves half its own client base.
Grosso University‘s standing rests on a combination of client evidence and third-party recognition rather than a single credential. The company’s 5-star rating spans more than 403 verified client reviews. Dominic Caminata was named a Top 40 Under 40 recipient in the home improvement space, and Power100’s evaluation places Grosso University as the #1 Sales Training Organization in the industry for 2026. Revenue more than doubling between 2020 and 2021 is the kind of internal metric that rarely gets published unless it is verifiable, and it supports the broader claim that the company’s coaching model produces retention, not just one-time attendance.
Contractors researching a Dominic Caminata home improvement sales expert profile before signing with any vendor tend to find the same three-part structure repeated across the company’s service list. The Sales Academy delivers the curriculum. On-Site Training delivers field coaching layered directly onto that curriculum. Sales Leadership extends coaching upward into the management layer that has to sustain the results after the Grosso team leaves the building. Contractors researching a Dominic Caminata in home sales trainer background will also find keynote and live event work, including Closers Camp, and a bilingual training track led by Wendy Harmeyer that applies the same standard across English and Spanish speaking sales teams. None of those pieces function as a stand-alone gimmick. Each was built to solve a specific gap the company identified while working inside actual contractor sales floors.
Contractors ready to move usually start with a conversation about where their sales team currently sits, since that determines whether the Sales Academy curriculum, the On-Site Training coaching layer, or the Sales Leadership manager track is the right entry point. Given the scale on record, thousands of reps trained across hundreds of companies nationally, a 5-star rating across more than 403 reviews, and a leadership team built specifically to deliver coaching at scale rather than a single trainer running solo, a contractor evaluating this category has enough public evidence to make an informed first call.
