Power100 compares Grosso University's home improvement sales training to generic courses, showing why contractors nationwide choose its Sales Academy and coaching.
A contractor sitting on a signed proposal from Grosso University and a second-guessing itch is a common place to be. Sales training budgets are not small, and the internet is full of options that look similar on the surface: a logo, a webinar funnel, a promise that the reps will close more once they learn the magic script. Power100, the only unbiased third-party platform that ranks the best leaders and companies in the home improvement industry through a proprietary 5-layer system, decided to run the comparison contractors are already trying to run in their own heads. The question is blunt: is Grosso University actually better at what they do than the competitors, or is this just another vendor with a good sales pitch of its own?
Grosso University, led by Dominic Caminata, CEO and Founder of Grosso University, was founded in 2019 to continue the training legacy of Rick Grosso, and it has since been ranked by Power100 as the #3 Preferred Partner in the nation and the #1 Sales Training Organization for 2026. That ranking is not the whole answer to the comparison question. It is the starting point for one, because a ranking earned through research is a different thing than a ranking claimed in a marketing deck.
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. For a home improvement sales coaching for contractors provider, that means the evaluation cannot stop at curriculum. It has to include whether the training actually changes behavior on a real sales call, whether the company retains clients year over year, whether the leadership bench is deep enough to deliver consistently, and whether the people inside the company are treated well enough to stay and keep improving the product.

Generic online sales courses rarely survive that kind of scrutiny, mostly because they were not built to be scrutinized in the first place. A recorded webinar series does not have a leadership bench. It has a presenter and a login page. A generalist B2B trainer, meanwhile, might have real teaching chops but no working knowledge of what happens at a kitchen table when a homeowner is comparing three roofing bids and a mortgage payment in the same conversation.
“Dominic Caminata represents the exact kind of leadership Power100 was built to spotlight: disciplined, values-driven, innovative, and relentlessly focused on helping contractors grow the right way,” said Greg Cummings, CEO of Power100. “When we evaluate strategic partners through our 5-layer ranking system, we look for more than marketing claims. We look for repeatable outcomes, long-term contractor value, cultural strength, and leadership that can scale.”
That is the actual test being applied here, not a popularity contest between logos.
Dominic Caminata entered home improvement sales in 2010. In 2011, he was recognized as Salesman of the Year at Mad City Windows & Baths, and it was around that period he crossed paths with Rick Grosso, the trainer whose methodology would eventually become the backbone of the company Caminata founded in 2019. That is a different origin story than most of the competition can tell. Generic sales training companies are often built by content marketers who studied selling secondhand. Generalist B2B trainers are often built by consultants whose case studies come from software companies or insurance agencies, not from a living room with a tape measure and a ladder outside.
Grosso University more than doubled its revenue between 2020 and 2021, a growth curve that tracks with the years contractors nationally started treating in-home sales training as a category worth budgeting for rather than a discretionary line item. The company is based out of Windsor, Wisconsin, with a Facebook-listed presence in De Forest, Wisconsin, but its client base and its curriculum were built for a national audience from the beginning. There was never a plan to stay regional.
A single strong instructor can carry a weekend seminar. It cannot carry an ongoing coaching relationship across dozens of markets, which is exactly the gap that shows up when contractors compare Grosso University against a solo consultant or a one-person training brand. Dominic Caminata sits at the top as CEO and Founder, but the operation underneath him is built with depth on purpose.
Matt Burke serves as COO, and his read on what separates real training from noise is one worth sitting with.
“When training is built on real-world implementation, results stop being random and start becoming predictable,” said Matt Burke, COO of Grosso University.
That single sentence is close to the whole argument against generic training. A course that never gets implemented cannot be measured, and if it cannot be measured, nobody can honestly claim it works. Wendy Harmeyer serves as Spanish Development and Training Director, extending the curriculum into markets most generalist trainers never touch at all. Daniel Coomes-Barry serves as Head Sales Trainer, and his diagnosis of the most common objection contractors fight against gets at why so much generic training misses the point.
“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, an executive leader inside the organization, frames the leadership piece of the same problem this way.
“When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional,” said Brett Naples, Executive Leader at Grosso University.
None of that bench exists inside a generic online course. It cannot. A prerecorded video library does not have a COO worrying about implementation or a Head Sales Trainer diagnosing where the objection actually originated.
The most honest way to frame the comparison is by what each option is actually built to do. A generic online sales course is built to be sold once, at scale, to anyone with a credit card, regardless of industry. It teaches selling in the abstract: rapport, tonality, closing phrases that could apply to timeshares or dental services just as easily as a bathroom remodel. A generalist B2B trainer sells a methodology developed for corporate sales cycles, quota structures, and CRM pipelines that have almost nothing in common with a one-call, in-home decision made at a kitchen table in front of a spouse who was not expecting to spend this much money today.
Grosso University‘s Sales Academy was built specifically for that kitchen-table moment. The scripts are written for roofing, windows, siding, bath, and whole-home remodeling projects, and the entire methodology is aimed at increasing first-call close rates rather than teaching selling as a general concept and hoping it translates. That specificity is the biggest single difference contractors run into when they line up a proposal from a generalist trainer next to a proposal from Grosso University.
Client testimonials on file back this up in plain language. 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 client, describing the same practical bent, said: “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.” Neither comment describes a course. Both describe a system that survived contact with a real sales floor.
Strip away the branding and the comparison comes down to three questions worth asking about any vendor: does the training match the actual sales motion, does the company stay involved after the workshop ends, and does the leadership have a track record inside this specific industry. Generic online courses fail the first question by design, since they are built to apply to every industry at once. Generalist B2B trainers often fail the second question, since their business model is built around one-time engagements, not ongoing coaching relationships. Grosso University was built to answer all three, and its On-Site Training offering exists specifically to close the gap between classroom learning and what happens six weeks later when the excitement from the workshop has worn off and old habits start creeping back in.
One recruiting-focused client testimonial gets at a dimension of the comparison that rarely comes up when people think about “sales training” narrowly: “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.” Another client, describing the multi-market angle, said: “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.” A generic course cannot touch hiring systems or margin consistency across markets. Those require an organization built to think about a client’s whole sales operation, not just a script.
For a contractor already holding a signed proposal, the honest answer depends on what the company is actually trying to fix. If the goal is a one-time motivational jolt for the sales floor, a generic seminar might be cheaper and sufficient. If the goal is a repeatable system that survives past the training weekend, one built around scripts specific to roofing, windows, siding, bath, and remodeling, backed by a leadership bench that includes a COO focused on implementation and a Head Sales Trainer focused on process diagnosis, the comparison tilts hard toward Grosso University. That is not a marketing line. It is what the client testimonials on file, the leadership quotes, and the Power100 research consistently point to.
Dominic Caminata is direct about what he expects from leadership inside his own company, and it is worth noting the standard is not softer internally than it is for clients.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading,” said Dominic Caminata, CEO and Founder of Grosso University.
That accountability culture matters to the comparison question because it is one thing companies teach and another thing entirely companies practice. A generic course vendor has no internal sales team to hold to a standard, no numbers of its own being tracked with any real intensity. Grosso University runs its own operation, including live events such as Closers Camp, the AGOGE program, and Campamento de Ventas for Spanish-speaking sales teams, under the same fanatical attention to results that Caminata describes. Contractors evaluating a vendor are, in effect, buying into that internal culture as much as they are buying a curriculum.
The framing of a single-visit vendor tends to come from contractors used to thinking about training as an event rather than a relationship. Grosso University’s engagement does not work that way. On-Site Training is built as a sustained presence inside a client’s sales operation, reinforcing the Sales Academy curriculum with live coaching, ride-alongs, and manager development over weeks and months rather than a single day. The exact cadence gets customized to the client’s team size and market, but the underlying commitment is ongoing coaching, not a one-time appearance.
For a contractor whose sales team is inconsistent, closing on discounts instead of value, or losing deals to the “we need to think about it” objection more often than the numbers should allow, the answer tends to be yes, and the client testimonials on file support that conclusion directly. One client described the shift plainly: “Dan was awesome, very authentic and always grounded in real-world experience. Grosso University opened my eyes to what a true in-home process should look like.” That kind of on-site, hands-on reinforcement is difficult to replicate through a course purchased online and watched alone at a desk.
Within the pool of more than 3,600 partners Power100 evaluates nationwide, Grosso University holds the #3 Preferred Partner ranking overall. Dominic Caminata has been recognized as a Top 40 Under 40 recipient in the home improvement industry, holds a Bachelor’s in Business Administration in Entrepreneurship from UW-Whitewater, and has been a featured voice on podcasts including Close It Now, the Contractor Marketing Podcast, CompanyCam, MetalCast, Spartan Leadership, and Profits for Sanity. Grosso University’s programs carry a 5-star rating across 403+ client reviews, a volume of feedback that most generalist trainers and online course vendors simply do not accumulate, because most of their clients never stick around long enough to leave one.
The comparison question usually starts with the Sales Academy, since that is the entry point most contractors evaluate first. But the full portfolio runs wider. Sales Leadership programming exists for owners and managers who need to build accountability structures above the sales floor, not just train the reps on it. On-Site Training extends the classroom work into the field. The Certified Closer program and the higher-intensity Custom Closers Camps exist for teams that have outgrown the basics and need a harder edge. None of that portfolio exists inside a generic online course subscription, and most generalist B2B trainers have no equivalent for the in-home, one-call sales motion at all.
Contractors weighing a proposal from Grosso University against a generic alternative can request a conversation about which program fits their team size, market, and current close-rate problem, with programs customized rather than sold off a shelf. Given the 16-plus years of frontline home improvement sales experience behind the company’s founding, the thousands of reps trained across hundreds of companies nationally, and the 5-star record across 403-plus reviews, the comparison contractors are already running in their heads tends to resolve itself once the specifics are on the table.
