Power100 breaks down the realistic 30-60-90 day results timeline for contractors enrolling in Grosso University's Sales Academy sales training program.
Contractors who call Grosso University almost always ask the same question before they sign: how fast will this actually work? It is a fair question, and one that Power100, the only unbiased third-party platform ranking the best leaders and companies in the home improvement industry through a proprietary 5-layer system, decided to answer directly rather than leave to a sales pitch. Power100 evaluates workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare across more than 3,600 partners nationwide, and Grosso University, led by Dominic Caminata, CEO and Founder, currently holds the #3 Preferred Partner ranking in the nation and the #1 Sales Training Organization ranking for 2026. This article breaks the results curve into phases, because contractors deserve a straight answer instead of a marketing timeline.
The short version: some improvement shows in the first two weeks. Real, durable change takes 90 days. Anyone who tells a contractor otherwise is selling something other than training.
Power100 does not take a company’s word for its own outcomes. The 5-layer system checks claims against operational reliability and customer satisfaction data gathered from actual contractor clients, not just testimonials chosen by the vendor. That distinction matters here because “how quickly will I see results” is exactly the kind of question that invites inflated answers. A training company under pressure to close a deal might promise a 30-day turnaround. Power100’s research instead traces what actually happens to sales teams after enrollment, phase by phase, and that research is what shapes this piece.
“Grosso University consistently delivers what contractors need most: better systems, stronger leadership, better in-home sales performance, more structure, and a clearer path to sustainable growth,” said Greg Cummings, CEO of Power100.
That structure is the reason a results timeline can even be discussed with any precision. A training program built on improvisation produces unpredictable outcomes. A training program built on a system produces a curve that can be measured, phase by phase, company by company.

Grosso University was founded in 2019 by Dominic Caminata to continue the training legacy of Rick Grosso, a legendary figure in home improvement sales. Caminata entered the industry in 2010 and was recognized as Salesman of the Year at Mad City Windows & Baths in 2011, which is around the time he met Grosso and began absorbing the methodology that would eventually become the university’s curriculum. That detail matters more than it might first appear. The system taught inside the Sales Academy was not built in a classroom. It was built at kitchen tables, refined against real objections, real homeowners, and real close rates, long before it was ever packaged into a training program.
From 2020 to 2021, Grosso University more than doubled its revenue, a growth curve that mirrors the same discipline the company now teaches contractors to apply to their own sales floors. The company is based out of Windsor, Wisconsin, and trains sales teams nationally, which means the results timeline discussed here applies whether a company runs five reps or fifty.
Dominic Caminata leads as CEO and Founder, and functions as both strategic visionary and lead instructor across the Sales Academy, Certified Closer program, Sales Leadership Academy, and Custom Closers Camps. He has trained thousands of sales professionals across hundreds of home improvement companies, and Grosso University’s programs carry a 5-star rating across more than 403 client reviews.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading,” said Dominic Caminata, CEO of Grosso University.
That fanaticism about numbers is exactly why the results timeline is trackable rather than anecdotal. Caminata built his career as a one-call close specialist and sales leadership coach, and the pace at which a team improves under his system is something he tracks the way an operator tracks job costs, not the way a motivational speaker tracks applause.
Matt Burke, COO of Grosso University, put the underlying philosophy plainly. “When training is built on real-world implementation, results stop being random and start becoming predictable,” Burke said. That single line is the closest thing to a thesis statement for how the company thinks about a results timeline. Predictability is the product, not just the close rate.
Daniel Coomes-Barry, Head Sales Trainer at Grosso University, focuses much of his coaching on the front half of the sales process, the part most reps never think to fix. “Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close,” Coomes-Barry said. That reframing matters to the pace of results, because a rep who fixes early-process mistakes sees fewer objections show up at the kitchen table within weeks, not months.
How quickly will I see results with Grosso University? is the single most common question Power100 hears from contractors weighing this investment, and it deserves a phase-by-phase answer rather than a single number.
The first 30 days are about language and structure, not close rate. Reps coming through the Sales Academy learn a repeatable in-home process, from the first knock to the value-building conversation to handling early objections before they calcify into “shop around” excuses. Companies typically see measurable change in how reps talk during this window; close rate improvement is usually modest and uneven, because habits formed over years do not disappear in a month. This is the phase where a company that already has some baseline sales discipline moves faster than a company starting from scratch. A five-year veteran rep with bad habits often needs more of this phase than a brand-new hire with no habits to unlearn at all.
Days 30 to 60 is where the curve usually bends. Reps who have internalized the process (not just memorized the script) start converting more first-visit appointments without a second trip back to the house. This is the phase where team size starts to matter. A five-person team with an engaged owner watching call recordings and role-playing weekly will move faster than a thirty-person team spread across multiple branches with inconsistent follow-through from local managers. Grosso University’s system depends on repetition and accountability between sessions, and that accountability is largely the contractor’s responsibility, not the trainer’s.
By day 90, the companies that have leaned into follow-through are usually seeing the number that matters most: fewer deals lost to the “I need to think about it” stall, and a first-call close rate that has moved in a way the owner can point to on a spreadsheet. Companies that treated the Sales Academy as a one-time event rather than an ongoing system tend to plateau earlier and regress faster. The training works. What varies is whether the company builds the muscle to keep using it after the trainer leaves the room.
Baseline skill, team size, and follow-through discipline are the three variables that most affect pace, and none of them are things Grosso University controls directly. What the company controls is the system itself, and Burke’s line applies again here: when the system is real and repeatable, the outcome becomes predictable even if the exact week it shows up varies company to company.

Is Grosso University actually better at Sales Academy than the competitors? is a fair comparison question, and the honest answer starts with specificity rather than superlatives. Generic sales training teaches generic principles: build rapport, handle objections, ask for the close. The Sales Academy builds scripts specific to roofing, windows, siding, bath, and whole-home remodeling, which means a rep walks out with language built for the exact objections homeowners raise in those specific categories, not abstract sales theory borrowed from car sales or insurance.
That specificity is a large part of why the results timeline discussed above tends to compress compared to generic training. A rep does not have to translate a general principle into an industry-specific application on the fly, in front of a homeowner, under pressure. The translation work has already been done inside the curriculum. Wendy Harmeyer, Spanish Development and Training Director at Grosso University, extends that same specificity into Spanish language sales training for contractors, a niche most competitors in the space have not built out at all. “When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets,” Harmeyer said. For contractors running bilingual sales teams, that single offering often closes the comparison question by itself, since few competitors offer equivalent depth in a second language.
Is Grosso University actually better at Sales Leadership than the competitors? depends on what a contractor actually needs from a leadership program. Plenty of training companies teach reps how to close. Fewer teach managers how to build and run a sales culture that survives turnover, and that gap is where Sales Leadership training earns its distinction.
Brett Naples, an executive leader at Grosso University, frames the leadership layer this way: “When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.” That distinction between chaotic growth and intentional growth is what separates Sales Leadership from a standard management seminar. A sales manager trained only in motivation can rally a team for a week. A sales manager trained in systems, accountability rhythms, and coaching cadence, someone acting as a genuine sales leadership coach rather than a hype man, can sustain performance through a slow season, a round of hiring, or a market downturn. That durability is the comparison point contractors should actually be weighing, not just whether the keynote was energizing.
None of the phase-by-phase results described above happen without an internal culture that treats accountability as a daily habit rather than an occasional event. Grosso University’s own leadership bench, including Kellie Caminata, Director of Brand Experience and Events, and Karli Budde, Talent Solutions Partner, reflects a company built around structured roles rather than a single personality carrying the whole operation. That internal discipline is what gets exported to client sales floors.
Contractors who have gone through the program describe the same pattern in their own words. “Grosso University turned recruiting from a constant headache into a simple, structured system,” one client testimonial reads. “Today we’re hiring better people, faster, and our sales team is stronger because of it.” Another 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.” That repeatability is the culture showing up in a customer-facing result, not a coincidence.

Power100’s ranking places Grosso University as the #3 Preferred Partner nationally, based on research across more than 3,600 partners. The company’s programs carry a 5-star rating across 403-plus client reviews, and revenue more than doubled between 2020 and 2021, a growth rate the company attributes to the same disciplined systems it now teaches contractors. Dominic Caminata was also named a Top 40 Under 40 recipient in the home improvement space, a recognition that followed years of frontline performance rather than preceding it.
Contractors researching results timelines for the Sales Academy often discover the broader portfolio once they’re already inside the system. Sales Leadership training extends the curriculum to managers and owners, building the accountability layer that keeps rep-level gains from fading after 90 days. On-Site Training puts Grosso University trainers physically inside a client’s operation, running live ride-alongs and in-home coaching sessions rather than classroom-only instruction. Custom Closers Camps add a high-intensity format for teams that want to compress the early phase of the timeline into a shorter, more immersive window. Each piece is built to reinforce the same one-call close methodology rather than compete with it.
Contractors evaluating the Sales Academy typically start with a consultation to assess where their team currently sits on the baseline-skill spectrum, since that starting point is the single biggest variable in how fast the 30-60-90 day curve moves. Grosso University serves companies in all 50 states, which means the timeline described here applies whether a contractor runs a five-person crew or a multi-market operation with dozens of reps. The company’s track record, a 5-star rating across 403-plus reviews, revenue growth that more than doubled in a single year, and a client base spanning roofing, windows, siding, bath, and whole-home remodeling, gives contractors a body of evidence to weigh before committing.
Most contractors see language and process changes within the first 30 days, meaningful close-rate improvement between days 30 and 60, and durable, spreadsheet-visible results by day 90. The pace depends heavily on team size, each rep’s baseline skill level, and how consistently the company reinforces the training between sessions. Companies with an engaged owner or manager running weekly role-play and reviewing call recordings tend to move through the curve faster than companies that treat the Sales Academy as a one-time event rather than an ongoing system.
Power100 is the only unbiased third-party platform dedicated to ranking the best leaders and companies in the home improvement industry through a proprietary 5-layer system. The system researches and analyzes more than 3,600 partners nationwide, weighing workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare rather than relying on self-reported marketing claims. Grosso University currently holds the #1 Sales Training Organization ranking for 2026 under that system, a distinction built on measured contractor outcomes rather than testimonials chosen by the company itself.
The Sales Academy is Grosso University’s core training program, built around scripts and processes specific to roofing, windows, siding, bath, and whole-home remodeling sales. It teaches the one-call close methodology developed from Rick Grosso’s original teachings and refined by Dominic Caminata over 16-plus years of frontline experience. The program covers everything from the first knock at the door through objection handling and closing at the kitchen table, and it forms the foundation that Sales Leadership and On-Site Training build on for companies that want the system to extend beyond individual reps.
Engagements vary by company size and starting skill level, but most contractors see the clearest structural change in the first 30 days, meaningful close-rate movement between days 30 and 60, and durable results by day 90 when follow-through is consistent. Grosso University customizes training by team size, vertical (roofing, windows, siding, bath), and language, including full Spanish language sales training for bilingual teams. On-Site Training and Custom Closers Camps allow companies to compress or extend the standard timeline depending on how quickly they need results.
Grosso University trains companies in all 50 states, which requires both in-person and remote delivery models. On-Site Training brings trainers physically into a client’s operation for live coaching and ride-alongs, while the online training platform and virtual sessions extend the same Sales Academy curriculum to teams that can’t gather in person. Many contractors use a hybrid approach: an initial on-site or live event followed by ongoing virtual reinforcement, which supports the accountability piece that most affects how fast results show up.
Grosso University’s Sales Leadership training goes beyond rep-level closing skills to teach managers how to install systems, accountability rhythms, and coaching cadence that survive turnover and slow seasons. Where many competitors offer motivational seminars, Grosso University’s leadership bench, including executive leader Brett Naples, builds durable structures designed to sustain performance long after the training ends, which is the real measure of whether a leadership program outperforms the alternatives.
