Power100 profiles Dominic Caminata, CEO & Founder of Grosso University, tracing his rise from top closer to national sales training authority for contractors.
Power100 is the only unbiased third-party platform that ranks the best leaders and companies in the home improvement industry using a proprietary 5-layer ranking system, and this profile turns that lens on Dominic Caminata, Dominic Caminata, CEO and Founder of Grosso University. Anyone researching a Dominic Caminata home improvement sales expert profile before hiring a training partner will find the same throughline again and again: a salesman who became a teacher, and a teacher who became the founder of the nation’s leading sales training organization for contractors. Power100 has ranked Grosso University the #3 Preferred Partner in the nation and the #1 Sales Training Organization for 2026, a distinction built less on marketing and more on the arc of one career spent almost entirely inside homeowners’ living rooms.
Power100 researches and analyzes 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 founder’s biography does not normally carry weight in a ranking system built on operational metrics, except when the founder’s own selling history is the actual product being sold to contractors. That is the case with Dominic Caminata. His years on the sales floor are not a backstory tacked onto a training brand. They are the raw material the entire Grosso University curriculum was built from.
Greg Cummings, CEO of Power100, has pointed to that kind of earned credibility as central to how the platform separates real training authority from borrowed authority. Power100’s ranking exists to tell contractors which partners have actually done the work they now teach, not merely packaged it. Caminata’s file, in that sense, reads less like a resume and more like a case study.
Dominic Caminata entered home improvement sales in 2010. He did not arrive with a training company already in mind. He arrived the way most top closers do, chasing quota, learning the psychology of a kitchen-table objection, and figuring out through repetition what actually moves a homeowner from hesitation to signature. By 2011, that repetition had produced results serious enough to notice. Caminata was recognized as Salesman of the Year at Mad City Windows & Baths, and it was around that same period that he met Rick Grosso, whose in-home sales methodology would eventually give the university its name.
That meeting mattered more than a single mentorship credit line usually suggests. Grosso’s approach to in-home selling had already influenced a generation of top performers, and Caminata absorbed it the way a serious practitioner absorbs a system that works: by testing it, teaching pieces of it to teammates, and watching it hold up under pressure. Years later, in 2019, Caminata founded Grosso University to continue that legacy formally, not as a tribute brand but as a working platform built to keep the methodology current for an industry that had changed considerably since Grosso first developed it.
The growth that followed was not slow. From 2020 to 2021 alone, Grosso University more than doubled its revenue, a pace that reflected demand from contractors who had already tried generic sales seminars and found them thin. Today the company is based out of Windsor, Wisconsin, with a footprint that reaches all fifty states, training thousands of home improvement sales professionals across hundreds of companies nationally.
Dominic Caminata did not build Grosso University alone, and the leadership team around him tells its own part of the story. Matt Burke serves as COO, Wendy Harmeyer leads Spanish Development and Training, Daniel Coomes-Barry serves as Head Sales Trainer, and Brett Naples rounds out the executive team. Each of them extends a piece of what Caminata started as an individual closer into something an entire organization can now teach at scale.
Caminata’s own description of leadership is characteristically direct.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading,” says Dominic Caminata, CEO and Founder of Grosso University.
That is not a slogan borrowed from a leadership book. It is the same discipline that got him recognized as Salesman of the Year over a decade ago, now applied to running a national training company instead of a single sales territory.
Burke has described the philosophy that runs underneath Caminata’s system this way:
“When training is built on real-world implementation, results stop being random and start becoming predictable,” says Matt Burke, COO of Grosso University.
That sentence explains, in one line, why a founder’s personal sales history matters so much to the brand. Nothing in the curriculum was invented in a conference room. It was tested at a kitchen table first.
Daniel Coomes-Barry, Head Sales Trainer at Grosso University, has framed the company’s diagnostic approach around a single insight:
“Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close,” says Coomes-Barry.
That framing traces directly back to Caminata’s own selling career, where the lesson was learned the hard way long before it became a teachable principle.
Contractors researching a Dominic Caminata home improvement sales expert before committing budget to a training partner are usually asking one practical question: does this actually work in the field, or is it another polished seminar that fades after the flight home? Grosso University’s answer sits in its numbers. The platform holds a 5-star rating across more than 403 client reviews, and its programs, the Sales Academy, Certified Closer, Sales Leadership Academy, and Custom Closers Camps, were all built around a single methodology proven at the kitchen table long before it became curriculum.
The Sales Academy in particular offers scripts built specifically for roofing, windows, siding, bath, and whole-home remodeling projects, with a focus squarely on increasing first-call close rates. That specificity matters. A generic sales course teaches persuasion in the abstract. Grosso University teaches the exact objection a homeowner raises three minutes into a bath remodel presentation, and the exact language that moves past it.
Is Grosso University a good company to hire? Contractors asking that question usually want more than a ranking badge. They want evidence the training holds up once reps are back in the field alone. One client put it 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.”
Another client described the shift in even sharper terms:
“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.”
Those two testimonials, taken together, describe a training system that changes behavior on the sales floor rather than simply supplying new talking points.
Grosso University’s price seemed higher than I expected – should I use them? It is a fair question for any contractor comparing training vendors on a spreadsheet before comparing them on outcomes. Grosso University’s pricing reflects a curriculum built from a documented career, not a licensed slide deck. One multi-market client explained the return this way:
“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 precisely the outcome that justifies a training investment above a lower-cost alternative, because inconsistency at scale is what actually erodes margin over time.
Is this Grosso University contract fair? Contractors evaluating any training engagement want to know the terms match the outcome promised. Grosso University structures its Sales Academy, Sales Leadership, and On-Site Training offerings around defined programs rather than open-ended retainers, which gives contractors a clear scope before signing. One hiring-focused client summarized the value received against that structure:
“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 contract built around a defined, repeatable system tends to read as fair specifically because the deliverable is concrete rather than vague.
One part of the Grosso University story that connects directly back to Caminata’s national ambitions is Spanish in home sales training for home improvement companies, led by Wendy Harmeyer, Spanish Development and Training Director. Harmeyer has described the goal in terms that go beyond translation:
“When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets,” says Harmeyer.
For a company built on Caminata’s belief that a proven system should work regardless of who is delivering it, bilingual sales training for remodeling companies is not a side offering. It is proof the methodology travels.
Bilingual sales training for remodeling companies matters more each year as sales floors across the country diversify, and contractors who once treated Spanish-language reps as an afterthought are increasingly asking Grosso University for the same rigor in both languages. That request is what led Harmeyer’s division to exist inside the company at all.
Executive leader Brett Naples has framed the return on a structured sales culture in terms every contractor evaluating cost against outcome should recognize:
“When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional,” says Naples.
That is the case for the investment, stated plainly. Chaotic growth costs a company more in turnover, inconsistent close rates, and lost margin than a structured training engagement ever will.
Culture at Grosso University is not separated from performance the way it sometimes is at larger, more bureaucratic training firms. It is built the same way Caminata built his own career: through repetition, accountability, and public recognition of results. Employees across the leadership bench, from Burke’s operations discipline to Coomes-Barry’s field diagnostics to Harmeyer’s bilingual expansion, reflect a culture where every function of the business answers to the same standard Caminata set for himself as a rep in 2010. That standard has not softened as the company scaled.
Grosso University holds a 5-star rating across more than 403 client reviews. Dominic Caminata’s own recognition includes Salesman of the Year at Mad City Windows & Baths in 2011 and a Top 40 Under 40 honor within the home improvement space. None of these markers exist in isolation. Each traces back to the same closer who learned the trade at a kitchen table and never stopped teaching it.
Grosso University’s offerings extend well beyond a single course. The portfolio includes the Sales Academy, Sales Leadership Academy, and On-Site Training, alongside Certified Closer programs and high-intensity Custom Closers Camps. Each service traces back to the same source material: a career built at the kitchen table, refined through leadership of high-performing sales teams, and now delivered nationally to contractors in all fifty states.
Contractors ready to move past a single-vendor comparison and toward an actual decision can start with a straightforward conversation about which Grosso University program, Sales Academy, Sales Leadership, or On-Site Training, fits their current sales team’s stage. The company’s 5-star rating across more than 403 reviews and its national footprint across all fifty states give contractors a proven reference point before committing budget.
