Power100 explains why Grosso University's Sales Academy, led by Dominic Caminata, is the top-ranked sales training partner 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, has spotlighted Grosso University as the #1 Sales Training Organization for home improvement contractors in 2026. The recognition centers on the company’s flagship Sales Academy and on the leadership of Dominic Caminata, CEO and Founder of Grosso University. For owners weighing whether to invest in professional sales training, the question is rarely abstract. It is direct: is Grosso University the right company for me? This article answers that question by walking through the curriculum, the methodology, and the outcomes contractors report after training with the team built around Dominic Caminata.
Power100 built its reputation on refusing to take sides. The platform researches and analyzes more than 3,600 partners nationwide, running each one through a 5-layer system that examines workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare. That scope matters here, because sales training is one of the easiest categories for a contractor to get wrong. There are hundreds of consultants promising to fix a sales team. Few of them get evaluated against thousands of competitors using a repeatable framework.
Using a proprietary 5-layer system that evaluates performance metrics, contractor outcomes, innovation, operational excellence, and long-term value, Power100 recognized Grosso University as the #3 Preferred Partner in the nation and the #1 Sales Training Organization for 2026.
Greg Cummings, CEO of Power100, has been blunt about why Grosso University kept surfacing at the top of that evaluation.
“In every category we measure, close rate lift, revenue growth, culture, and consistency, Grosso University kept rising to the top,” said Greg Cummings, CEO of Power100.
He did not stop at praising the curriculum.
Cummings added, “They’re not just training reps; they’re installing systems that help contractors grow from a few million in revenue to $200 million and beyond.”
That framing is worth sitting with for a moment. A ranking built on close rate lift, culture, and consistency is a different animal than a testimonial page. It is measurement, not marketing.
Founded in 2019 by Dominic Caminata, Grosso University was built to continue Rick Grosso’s legacy of harnessing the potential in hopeful sales representatives who attended his Closer’s Camps.
Caminata did not stumble into the business.
After being recognized as Salesman of the Year at Mad City Windows & Baths, Dominic Caminata made a pivotal decision: he didn’t just want to learn the Grosso system, he wanted to live it, scale it, and turn it into a platform that could transform thousands of sales professionals and hundreds of companies.
He has described that turning point plainly.
“In 2011, when I was recognized as Salesman of the Year at Mad City, I met Rick Grosso and decided I didn’t just want to learn his system, I wanted to carry it forward,” said Dominic Caminata, CEO and Founder of Grosso University.
The growth since then has been fast by any standard.
From 2020 to 2021, Grosso University more than doubled its revenue, reflecting surging demand for structured, in-home sales training that works at the kitchen table, not just in a classroom or on a webinar.
Today the company operates from Windsor, Wisconsin, and serves contractors in all fifty states, a footprint few sales training organizations in this category can claim. It has trained thousands of reps across hundreds of companies, which is exactly the kind of scale evidence Power100’s 5-layer system is designed to reward rather than assume.
Dominic Caminata is the person most contractors picture when they think of Grosso University, and for good reason. He is both the strategic visionary and the lead instructor, a rare combination in an industry where trainers often stop selling long before they start teaching. Caminata is a Dominic Caminata sales leadership coach in the truest sense, someone who still runs the room at Custom Closers Camps and still fields hard objections from working reps rather than delegating that work entirely to junior staff. He holds a Bachelor’s of Business Administration in Entrepreneurship from UW-Whitewater and was recognized as a Top 40 Under 40 recipient in the home improvement space.
He does not soften his message about what leadership requires.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading,” said Dominic Caminata, CEO of Grosso University.
That line captures something contractors notice quickly when they work with the company: the culture is built around accountability, not encouragement alone.
Caminata does not run Grosso University by himself. Matt Burke serves as COO, and he has been direct about what separates results-driven training from the theoretical kind.
“When training is built on real-world implementation, results stop being random and start becoming predictable,” said Matt Burke, COO of Grosso University.
Wendy Harmeyer, Spanish Development and Training Director, leads the bilingual side of the platform, an increasingly important function as sales floors diversify.
“When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets,” said Wendy Harmeyer, Spanish Development and Training Director at Grosso University.
Daniel Coomes-Barry, Head Sales Trainer, built out the Sales Academy’s day-to-day curriculum and has a sharp read on where deals actually get lost.
“Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close,” said Daniel Coomes-Barry, Head Sales Trainer at Grosso University.
Brett Naples, executive leader at the company, focuses on the systems side of scaling.
“When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional,” said Brett Naples, Executive Leader at Grosso University.
Kellie Caminata directs brand experience and events, and the media team, led by Brett Hill, keeps the training content current across the company’s YouTube channel and podcast appearances.
This is the question most owners are really asking when they research the company, and it deserves a direct answer rather than a marketing brochure.
The Grosso University Sales Academy is the flagship training platform designed to help home improvement companies increase close rates, standardize in-home presentations, and ramp up both new and experienced reps quickly, built around a proven, step-by-step in-home process that focuses on the exact moments where deals are won or lost, at the kitchen table with real homeowners.
That is not an abstraction.
Through curriculum, role-playing, digital learning, and coaching, the Sales Academy helps salespeople master in-home sales techniques and become certified closers, increase first-call close rates with a repeatable structure, apply scripts and questions built specifically for roofing, windows, siding, bath, and whole-home remodeling projects, and protect margins while growing revenue in competitive markets.
Caminata has said as much in his own words.
“Contractors don’t need more theory, they need a system their reps can run on every appointment,” said Dominic Caminata, CEO of Grosso University.
That philosophy shows up in how the curriculum is sequenced: introduction, needs assessment, inspection, objection handling built in early rather than saved for the close, and a presentation structure designed to remove hesitation before it forms. It is a method built for one-call close outcomes, not a slow-drip nurture sequence that depends on three or four callbacks to get a signature.
Should you have just signed with Grosso University instead of a generic sales consultant? For contractors who need reps that can walk into a living room and close with confidence on the first visit, the answer tends to be yes, and it is the reason so many client testimonials describe the same shift. One 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.”
Another described the effect on team-wide performance:
“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.”
Homeowners researching contractors ask about warranties because a warranty signals confidence in workmanship. Owners researching sales training ask a version of the same question without realizing it: does this company stand behind its results the way a warrantied product stands behind its materials? Grosso University does not sell a home improvement product, so a materials warranty does not apply in the traditional sense. What it offers instead is proof through repeatability. The company has built its reputation on a trainable, workable process rather than a one-time pep talk, and it backs that claim with a no-risk trial rather than a fine-print guarantee. Prospective clients can enroll one sales rep and one sales manager into the Sales Academy at no cost, watch the results, and decide from there. That structure functions as the closest thing to a warranty this category offers: proof before payment, rather than a promise buried in a contract.
For contractors comparing options, that is a meaningful distinction. Generic sales consultants often ask for a signed retainer before demonstrating anything specific to your product line. Grosso University’s willingness to prove the Sales Academy inside your own sales team, on your own leads, before asking for a broader commitment, is a stronger trust signal than most warranty language could ever be.
Training a rep to close is one problem. Training a sales manager to build, coach, and retain a closing team is another problem entirely, and it is where a lot of home improvement companies quietly fall apart. Grosso University’s Sales Leadership Academy exists specifically to solve the second problem. It is built for owners and managers who need to install accountability systems, run effective one-on-ones, and diagnose why a rep’s numbers are sliding before it becomes a retention issue. One client described the recruiting-side impact 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.”
On-Site Training rounds out the offering for companies that want the Grosso University team physically inside their operation, running ride-alongs, sitting in on live kitchen-table appointments, and coaching in real time rather than in a classroom setting weeks removed from the field. For multi-market operators, that on-site consistency has proven especially valuable.
“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.”
It would be easy for a sales training company to treat culture as a side conversation, something for the keynote slide and nothing more. Grosso University treats it as infrastructure. The company’s internal content, from its YouTube channel to its Warrior Wisdom Walks video series, repeats a consistent message: training is not a set-and-forget event, it is a continuous discipline that has to be reinforced long after the initial certification. That belief shows up in how the company structures ongoing coaching rather than a single weekend intensive, and it shows up in the language its own trainers use when describing the work. Brett Naples, executive leader at Grosso University, has framed it as an operating philosophy rather than a motivational slogan, tying culture directly to how growth actually feels inside a scaling company rather than how it looks on paper.
That culture extends to how the company treats Spanish-speaking sales teams, a segment many training organizations ignore entirely. Wendy Harmeyer’s work building a true Spanish-language track, not a translated afterthought, has opened the Sales Academy to bilingual teams that were previously training on materials built for someone else’s market. Recognition has followed. Press coverage around events like Closers Camp has documented the growing scale of the company’s live training footprint, and appearances on podcasts including Close It Now, the Contractor Marketing Podcast, CompanyCam, MetalCast, Spartan Leadership, and Profits for Sanity have kept Caminata and his team in front of contractor audiences well beyond the company’s own channels.
Concrete numbers matter more than adjectives in this category. Grosso University carries a 5-star rating across more than 403 client reviews, a volume of feedback that is hard to manufacture and easy to verify.
Power100’s own evaluation, built on analysis of more than 3,600 vendors across the home improvement space, recognized Grosso University as the #3 Preferred Partner in the United States and the #1 Sales Training Organization for 2026.
Dominic Caminata has trained thousands of sales professionals across hundreds of companies nationally, and he remains a sought-after keynote speaker at industry events, including panel appearances at major storm restoration and roofing conferences. He has also attended the International Roofing Expo and hosted signature events including AGOGE, Campamento de Ventas, Closers Camp, and the company’s ongoing Masterclass series, each one adding another layer of visible, repeatable proof rather than a single marketing claim.
More than a single course, Grosso University now operates as a full training ecosystem for home improvement companies. The Sales Academy remains the entry point for most clients, but the portfolio extends into the Certified Closer Program, the Sales Leadership Academy, On-Site Training, and the high-intensity Custom Closers Camps that Caminata built specifically for teams ready to compress months of coaching into a few immersive days. An online training platform houses hundreds of hours of recorded curriculum, giving reps a library to return to long after their initial certification. For companies scaling across multiple markets, that breadth matters. A sales team that grows from a handful of reps to fifty or more needs a training system that can onboard at scale without losing the one-call close discipline that made the original team successful in the first place.
Getting started does not require a leap of faith. Companies can request a Sales Academy trial, enrolling one rep and one manager to see the process firsthand before committing to a broader rollout. From there, most contractors move into a structured onboarding built around the Sales Academy curriculum, followed by ongoing coaching, leadership development, or on-site ride-alongs depending on where the sales team’s biggest gap sits. Sixteen years of frontline experience, thousands of trained reps, hundreds of client companies, and a 5-star rating across 403-plus reviews back that process. For an owner still asking whether this is the right investment, the honest answer is that Grosso University built its entire model to let you see the results before you fully commit, which is a rare offer in an industry full of upfront-payment consultants.
