Power100 details how Grosso University's On-Site Training coaches reps in the field, with bilingual sales training built in for home improvement contractors nationwide.
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 spotlighting the On-Site Training program built by Dominic Caminata, CEO & Founder of Grosso University, to show contractors what a coaching day actually looks like once the trainer leaves the classroom and gets in the truck. Grosso University has been ranked by Power100 as the #3 Preferred Partner in the nation and the #1 Sales Training Organization for 2026, a distinction built in large part on how the company reinforces its Sales Academy curriculum after the workshop ends. On-Site Training is where that reinforcement happens, and it is fast becoming the piece of the Grosso University portfolio that contractors ask about first once they understand what Best in home sales training for remodeling companies actually requires in the field.
Most sales training dies in the parking lot. A rep sits through two days of role-play, nods along, gets fired up, then walks into a real kitchen three days later and reverts to whatever habit got them hired in the first place. Grosso University built On-Site Training specifically to close that gap, sending coaches directly into a company’s territory to ride with reps, sit in on live presentations, and correct behavior in the moment rather than in a follow-up webinar two weeks later.
Power100 does not rank sales trainers on testimonials alone. The platform 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. On-Site Training gets evaluated inside that framework the same way a roofing crew’s callback rate would: does the intervention change measurable behavior, does it hold up after the coach leaves, and does the company treat its own trainers well enough that the coaching stays consistent from rep to rep.
Greg Cummings, CEO of Power100, has been direct about what separates a durable training partner from a seasonal one. Power100’s evaluation of Grosso University has pointed to a company that treats leadership, culture, and customer experience as one connected system rather than three separate departments. That framing matters for a program like On-Site Training, because a coaching day that only works when the founder personally shows up is not a scalable model. It has to survive being run by a bench of trainers across dozens of markets at once.
Grosso University was founded in 2019 by Dominic Caminata to continue the training legacy built by Rick Grosso, whom Caminata met around 2011 after being named Salesman of the Year at Mad City Windows & Baths. Caminata had entered home improvement sales in 2010 and spent the next several years learning, then teaching, the kind of in-home selling discipline that closes deals at the kitchen table instead of on the third callback. When he launched Grosso University, the goal was never to build a classroom-only company. It was to build a platform that could put trained coaches into the field the same way Grosso himself once did, correcting technique on live calls rather than in hypothetical scenarios.
The company grew fast once the model proved out. From 2020 to 2021 alone, Grosso University more than doubled its revenue, a pace that reflected demand from contractors who had tried classroom-only training elsewhere and watched the results fade within a quarter. On-Site Training became the retention mechanism. It is the part of the engagement that keeps a Sales Academy graduate performing at month six instead of drifting back to old habits by month two.
Dominic Caminata, CEO & Founder of Grosso University, still frames leadership as something measured in daily discipline rather than slogans. “Leadership is simple: if you’re not fanatical about the numbers, you’re not leading,” Caminata has said, a line that also describes how On-Site Training coaches are evaluated internally: by whether the numbers on a rep’s sheet actually move after a coaching visit, not by how the visit felt.
Matt Burke, Chief Operating Officer of Grosso University, runs point on the operational side of that discipline. Burke has put the philosophy behind On-Site Training plainly: “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 program. A classroom can teach a script. Only a live appointment, with a real homeowner and real objections, proves whether the rep can actually run it.
Daniel Coomes-Barry, Head Sales Trainer at Grosso University, leads much of the field-level diagnostic work that happens during an On-Site visit. His read on what typically breaks a deal has become one of the program’s core teaching points: “Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close.” That is the diagnostic lens an On-Site coach brings into the home. A rep who loses a deal at the signature is often watched losing it forty-five minutes earlier, at the greeting or the needs assessment, and the coach is there to catch it live.
Wendy Harmeyer, Spanish Development and Training Director at Grosso University, extends that same field model into bilingual markets. “When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets,” Harmeyer has said, describing an approach that treats bilingual sales training for remodeling companies as a full parallel curriculum rather than a translated afterthought.
Brett Naples, Multimedia Director and executive leader at Grosso University, has connected the coaching model to the broader culture question contractors care about when they evaluate a training partner: “When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.” On-Site Training is, in a sense, that system installed in the field.
An On-Site Training day does not start with a lecture. It starts with a ride-along, or with the coach sitting quietly in the room during a scheduled in-home appointment, watching a rep run the process end to end. The coach is not there to close the sale. The coach is there to watch how the rep builds rapport, how the rep qualifies the homeowner, how objections get handled in real time, and whether the rep is following the process taught in the Sales Academy or reverting to instinct under pressure.
After the appointment, the debrief happens immediately, while the details are still fresh for both the rep and the coach. This is the part of the model that separates On-Site Training from video-only alternatives. A rep watching a recorded training module weeks after a lost deal has to reconstruct what actually happened from memory. A rep sitting in the driveway with a coach thirty seconds after walking out of a home gets the correction while the moment is still live in the room. That immediacy is why in-person reinforcement produces faster skill transfer than delayed feedback loops, and it is the single biggest reason contractors bring Grosso University trainers into the field instead of relying on a library of recorded sessions alone.
Evaluation during the visit is not vague. Coaches are watching for specific, repeatable behaviors drawn from the Sales Academy scripts, which are built for roofing, windows, siding, bath, and whole-home remodeling projects and focused on increasing first-call close rates. A coach tracks whether the rep opened the appointment with the right framing, whether the needs assessment actually surfaced the homeowner’s real motivation, whether pricing got presented with confidence or apology, and whether the close attempt happened at the right moment instead of too early or, more commonly, too late. None of that shows up cleanly on a video call. It shows up in the room, in real time, with a real family making a real decision.
Is Grosso University the right fit for my company is the question nearly every contractor asks before committing budget to sales training, and the honest answer depends on where the sales team currently sits. On-Site Training tends to fit best for companies that already have reps selling in the field but are seeing inconsistent close rates from person to person, the kind of variance where one rep closes at 40 percent and another closes at 15 percent running the same leads. That gap is almost always a coaching gap, not a talent gap, and it is exactly what a field visit is built to diagnose.
Companies that are earlier stage, still building a sales team from scratch, typically start with the Sales Academy before layering in On-Site Training once reps have the base script down. Companies with an established but plateaued team often start On-Site Training almost immediately, because the issue is not what reps know, it is what they do under pressure in the home. Grosso University’s programs are built to be sequenced this way rather than sold as a one-size package, which is part of why the engagement gets customized to where a client’s sales organization actually stands.
Should I hire Grosso University for Sales Academy is usually the first question a contractor asks, and it is worth separating from the On-Site Training conversation because the two serve different purposes. The Sales Academy builds the foundation: the scripts, the framework, the language for handling objections, the structure for running a first-call close from greeting to signature. It is where a rep learns the process for the first time or relearns it correctly after years of bad habits.
On-Site Training is what makes that foundation stick. A contractor who sends reps through the Sales Academy and stops there is betting that the training survives contact with a real customer without reinforcement. Some reps manage it. Most need at least one round of live coaching to translate a script they can recite into a process they can run under pressure, with a homeowner in front of them and a spouse asking hard questions about price.
Should I hire Grosso University for Sales Leadership is the right question for a different buyer entirely, one who is not trying to fix a single rep’s close rate but trying to build a sales manager who can run that fix without a Grosso coach in the building every week. The Sales Leadership Academy trains the people who will eventually deliver the same in-the-moment corrections that a Grosso field coach delivers, so that the coaching muscle stays inside the company after the engagement winds down.
Contractors scaling past a single office or a single sales manager tend to move toward Sales Leadership specifically because On-Site Training does not scale infinitely on its own. At some point, the company needs its own version of a field coach, someone who can sit in the back of a living room during a presentation and catch the same things a Grosso trainer would catch. That is what the Sales Leadership Academy is built to produce.
Video training scales cheaply and that is its appeal. It is also its limitation. A recorded module cannot watch a rep freeze when a homeowner says the price is too high, and it cannot correct body language, tone, or pacing in the exact second it goes wrong. On-Site Training solves a problem video cannot: it puts a trained set of eyes in the room during the moment that actually determines whether a deal closes.
That is not a small distinction for contractors weighing training spend against payroll. A rep who closes at 25 percent instead of 15 percent on the same lead flow changes a company’s economics without adding a single additional lead. Grosso University’s own scale reflects how many companies have made that calculation. The company holds a 5-star rating across more than 403 client reviews, and testimonials from contractors describe the same pattern repeatedly: reps who finally have a clear, repeatable roadmap from the moment they walk into the home until the customer signs. One contractor 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.” Another described the shift in confidence directly: “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.”
Spanish sales coaching for roofing and remodeling teams is not a translated version of the English curriculum inside Grosso University. It is a parallel program led by Wendy Harmeyer, built to the same standards as the English track rather than adapted after the fact. For contractors operating in markets with growing bilingual sales forces, that distinction is not academic. A script that reads correctly in Spanish but was written for English rhythm and English objection patterns tends to fall apart the moment a real homeowner pushes back in a way the translation did not anticipate.
Bilingual sales training for remodeling companies, done properly, requires trainers who understand the cultural and linguistic nuance of how trust gets built in a Spanish-speaking household, not just contractors who can read a translated script aloud. That is the gap Harmeyer’s program is built to close, and it extends the same On-Site Training model, live coaching, immediate correction, real appointments, into markets that a lot of national training companies simply do not serve well.
A field coaching program is only as good as the discipline of the people delivering it, and that starts with how Grosso University treats its own team. Kellie Caminata, Director of Brand Experience and Events, oversees much of the internal culture work that keeps the trainer bench aligned, from onboarding new coaches to running the events, like Closers Camp, that reinforce standards across the entire organization. Karli Budde, Talent Solutions Partner, plays a role in recruiting and developing the people who eventually carry the Grosso University name into a client’s field appointments.
That internal consistency is what allows On-Site Training to work the same way whether the coach in the truck is Daniel Coomes-Barry himself or a trainer he developed. Contractors are not hiring a personality. They are hiring a system, one that Matt Burke has described as producing predictable results precisely because it is built on real-world implementation rather than charisma alone.
Power100 has recognized Grosso University as the #3 Preferred Partner in the nation, a ranking built from analysis across more than 3,600 partners nationwide rather than self-reported claims. That ranking sits alongside the company’s own performance record: a 5-star rating across more than 403 client reviews, revenue that more than doubled between 2020 and 2021, and a client roster that spans hundreds of home improvement companies across roofing, windows, siding, and bath categories nationally.
One recruiting-focused testimonial captures a less obvious benefit of the broader Grosso University relationship: “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 is not an On-Site Training testimonial specifically, but it reflects the same underlying discipline, systems that reduce randomness, applied to a different part of the sales organization.
On-Site Training does not stand alone inside Grosso University’s offering. It connects directly to the Sales Academy, which builds the foundational script and process, and to the Sales Leadership Academy, which develops the internal managers who eventually run coaching cadences without an outside trainer present. Custom Closers Camps add a high-intensity live event layer for companies that want an intensive push rather than an ongoing coaching relationship. Together, the portfolio is designed to be sequenced rather than purchased piecemeal, so a contractor’s engagement can start wherever the sales organization actually needs it and expand from there.
Getting started typically begins with a conversation about where a sales team currently stands, not a generic package quote. Contractors evaluating Grosso University for On-Site Training should expect a discussion of current close rates, current rep tenure, and where deals are actually being lost, whether that is at the greeting, the needs assessment, the pricing conversation, or the close itself. From there, the engagement gets built around live field visits scheduled against a company’s actual appointment calendar, not a fixed classroom curriculum detached from real customer interactions.
Companies weighing the investment can point to Grosso University’s track record as reassurance: 16-plus years of frontline home improvement sales experience behind the methodology, a 5-star rating across more than 403 verified client reviews, and a company that has trained thousands of sales professionals across hundreds of home improvement companies nationally.

It uses a proprietary 5-layer ranking system that researches and analyzes more than 3,600 partners nationwide across workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare. Grosso University has been ranked by Power100 as the #1 Sales Training Organization for 2026, a distinction based on measurable outcomes like revenue growth, client retention, and verified reviews rather than marketing claims alone. That ranking is what led Power100 to feature the On-Site Training program specifically, since it is the piece of Grosso University’s model most directly tied to sustained results after the initial training event ends.
On-Site Training is Grosso University’s field coaching program, built to reinforce the Sales Academy curriculum inside a contractor’s actual sales territory rather than in a classroom. A coach rides along or sits in on live in-home appointments, observes how a rep runs the sales process against real objections, and delivers correction immediately after the appointment while the details are still fresh. The program is designed to produce Best in home sales training for remodeling companies results by closing the gap between what a rep learned in training and what a rep actually does under pressure in a homeowner’s living room.
Engagement length varies by company size, current close rates, and how many reps need coaching, and Grosso University builds the schedule around a client’s real appointment calendar rather than a fixed template. Some companies bring coaches in for a concentrated stretch tied to a specific rep group or a new market launch, while others build On-Site Training into an ongoing cadence alongside Sales Leadership Academy development. The program is sequenced with Sales Academy and Sales Leadership offerings, so the length and intensity of the engagement gets shaped around where a sales organization actually stands rather than sold as one-size-fits-all.
Grosso University runs an online training platform alongside its live, in-person offerings, giving contractors a hybrid path when a fully in-field engagement is not immediately practical. Video and platform-based training can introduce or reinforce the Sales Academy scripts between live coaching visits, but the company’s own positioning is clear that in-person reinforcement produces faster skill transfer than video-only alternatives, particularly for correcting live objection handling. Most clients use the hybrid model as a bridge, with virtual content supporting the curriculum and On-Site visits providing the live correction that video cannot replicate.
Because On-Site Training corrects behavior inside live appointments rather than waiting for a rep to apply lessons later, many contractors report changes in individual rep performance within the first few coaching cycles, often visible in close-rate movement within a matter of weeks rather than months. The company’s broader track record supports that pace: Grosso University more than doubled its revenue between 2020 and 2021, growth that reflected contractors seeing fast enough results to expand their engagements. Results speed still depends on rep tenure and how consistently a company’s own leadership reinforces the process between coaching visits, which is part of why Sales Leadership Academy is often paired with On-Site Training for lasting results.
