Power100 spotlights Grosso University's Spanish in home sales training for home improvement companies, the #1-ranked system building bilingual closing teams nationwide.
A remodeling company owner posts a job listing for a bilingual sales rep. The applications come in fast, because Spanish-speaking talent is out there and homeowners who prefer Spanish are a growing share of the market in roofing, windows, siding, and bath. Then the harder question shows up: once that rep is hired, what exactly do you train them on? Translate the English script and hope it lands? Or build something that was actually designed, from the studs out, for a Spanish-speaking sales conversation at the kitchen table?
Power100, the only unbiased third-party platform that ranks the best leaders, companies, and strategic partners in the home improvement industry through a proprietary 5-layer ranking system, has spent time inside that question. The answer keeps leading back to Grosso University, a national sales training organization led by Dominic Caminata, CEO and Founder of Grosso University, and a company Power100 ranked as the #3 Preferred Partner in the nation and the #1 Sales Training Organization in the home improvement industry for 2026. Its Spanish in home sales training for home improvement companies is built directly on the belief that a bilingual closing system only works when it is trained, not translated.
Power100 researches and analyzes more than 3,600 partners nationwide through a 5-layer proprietary system that examines workmanship quality, operational reliability, customer satisfaction, innovation, and employee welfare. A Spanish-language curriculum gets tested against all five layers, not judged as a side project or a nice-to-have add-on tacked onto an English program. Does it produce reps who can actually close at the kitchen table? Is it repeatable across markets and companies? Does it hold up when a contractor scales from one bilingual rep to a full bilingual team?
Greg Cummings, CEO of Power100, frames the evaluation around leadership and culture as much as curriculum. Grosso University’s leadership bench, built specifically to support a Spanish-language program rather than borrow one, is a large part of why the company keeps clearing that bar.
Grosso University was founded in 2019 by Dominic Caminata to continue the training legacy of Rick Grosso, the legendary in-home sales trainer whose kitchen-table methodology shaped a generation of home improvement closers. Caminata entered home improvement sales in 2010 and was recognized as Salesman of the Year at Mad City Windows & Baths in 2011, the same period he crossed paths with Grosso. From 2020 to 2021, the company more than doubled its revenue, a growth rate that forced a decision most training companies never face: expand the curriculum in English only, or build something that could genuinely serve a bilingual sales force.
Grosso University chose the harder path. Rather than hand a Spanish-speaking rep a translated script and call it training, the company built a dedicated Spanish development track led by a named director with the language expertise to make it real. That decision is a big part of why Spanish-language capability sits inside the core curriculum today instead of existing as an afterthought.
Dominic Caminata leads the company as its CEO and Founder, and he is often described by clients and colleagues as a Dominic Caminata in home sales trainer first, a title earned on the sales floor before it ever showed up on a business card. He built his credibility as a Dominic Caminata sales leadership coach the same way, by producing measurable results with real sales teams before turning that experience into a national platform.
Caminata does not run the Spanish-language program alone, and he would be the first to say so. Wendy Harmeyer serves as Spanish Development and Training Director, a role created specifically because Grosso University’s leadership decided a translated script was not good enough. Matt Burke serves as COO, overseeing how training programs get implemented across client companies. Daniel Coomes-Barry serves as Head Sales Trainer, and Brett Naples holds an executive leadership role inside the organization.
“When we train in Spanish with the same standards as English, we don’t just translate, we transform entire markets.”
— Wendy Harmeyer, Spanish Development & Training Director, Grosso University
That line matters because it draws a line most training companies never bother drawing. A translated script assumes the words are the product. Harmeyer’s program treats the standard, the process, the objection handling, and the close as the product, with Spanish as the language it happens to be delivered in.

Caminata ties that same discipline back to leadership at the top of the organization.
“Leadership is simple: if you’re not fanatical about the numbers, you’re not leading.”
— Dominic Caminata, CEO & Founder, Grosso University
Ask a remodeling company owner who has hired a bilingual rep without a real training system what happened, and the story is usually the same. The rep is a strong closer socially, likeable, hardworking, good with people. But the sales process itself was never designed in Spanish. It was patched together, borrowed from the English deck, run through a translation tool, and handed over with a shrug. Objection handling breaks down. Qualifying questions land wrong. The rep improvises, and improvising at the kitchen table is expensive.
Grosso University’s Sales Academy avoids that trap by building scripts for roofing, windows, siding, bath, and whole-home remodeling projects with the specific goal of increasing first-call close rates, and the Spanish track mirrors that same structure rather than approximating it. The process discipline that shows up in the English curriculum, the pre-approach, the qualifying conversation, the value build, the objection sequence, the close, gets rebuilt in Spanish rather than translated line by line. That distinction is the entire value proposition. A remodeling company owner who signs a bilingual rep expecting a real closer needs a training system that treats Spanish-speaking homeowners with the same rigor as English-speaking ones, not a lighter version of the real program.
Daniel Coomes-Barry, Head Sales Trainer at Grosso University, puts a version of that discipline in blunt terms that applies across both languages.
“Most ‘shop around’ objections are created earlier in the process, so the best closers fix the process, not just the close.”
— Daniel Coomes-Barry, Head Sales Trainer, Grosso University
That principle does not change when the conversation happens in Spanish. If anything, it matters more, because a bilingual rep who has never been trained on process discipline is more likely to fall back on charm alone, and charm alone eventually meets a homeowner who needs more than charm.
Start with hiring. Companies bringing on Spanish-speaking reps often hire for language first and sales aptitude second, which inverts the order that actually produces closers. Grosso University’s training model assumes both matter, and it gives owners a framework to evaluate candidates on sales fundamentals, not just fluency. A bilingual rep who cannot qualify a lead or handle a price objection in English will not magically solve those problems by switching languages.
Training cadence comes next. On-Site Training gives contractors a way to bring Grosso University’s Spanish Development curriculum directly into their own sales floor, rather than sending one rep off to a generic seminar and hoping the material transfers. The cadence matters because sales training that happens once and never gets reinforced fades within weeks. Grosso University builds its programs around live implementation, not a single event.
“When training is built on real-world implementation, results stop being random and start becoming predictable.”
— Matt Burke, COO, Grosso University
Language-specific closing tools round out the system. Objection scripts, qualifying questions, and value-building language get built for how Spanish-speaking homeowners actually think and talk about a purchase decision, rather than reverse-engineered from an English deck. A remodeling company scaling a bilingual sales team is not just adding headcount. It is adding a second closing language that has to hold up under the same standard as the first one, and that standard is the entire point of the program.

A training company can only teach discipline it practices internally. Grosso University’s leadership structure, with named roles for Spanish Development, sales leadership, and operations, reflects a culture that treats specialization seriously rather than stretching one trainer across every function. Brett Naples, an executive leader inside the organization, has spoken to how that structure translates into growth that feels intentional rather than reactive.
“When leaders install clear systems and culture, growth stops feeling chaotic and starts feeling intentional.”
— Brett Naples, Executive Leader, Grosso University
That internal culture shows up externally in a specific way. Clients who have gone through Grosso University’s broader training programs describe a system, not a personality, doing the work. One client put it this way about the company’s hiring and training impact more broadly: “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 described the process discipline directly: “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.”
Grosso University carries a 5-star rating across more than 403 client reviews, a scale that spans companies far larger than any one bilingual sales team. The company has trained thousands of sales professionals across hundreds of home improvement companies nationally since Caminata founded it in 2019, and its revenue more than doubled between 2020 and 2021, a growth curve that tracks with the industry’s shift toward bilingual sales capacity. That record sits underneath Power100’s recognition of the company’s Sales Training Organization ranking for 2026, evaluated against more than 3,600 partners nationwide through the platform’s 5-layer system.
One client testimonial speaks directly to the kind of consistency Spanish-language training is meant to deliver at scale: “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.” That is the outcome a remodeling company owner should expect from a bilingual closing system built correctly: consistency across markets and languages, not a patchwork of scripts that only work when the right rep happens to be in the room.
Spanish in home sales training for home improvement companies is one piece of a broader portfolio. Grosso University’s Sales Academy covers the full in-home process for roofing, windows, siding, bath, and whole-home remodeling projects. Its Sales Leadership Academy trains owners and managers on accountability, recruiting, and manager development, the layer above individual closing skill. On-Site Training brings any of these programs, including the Spanish curriculum, directly into a contractor’s own sales floor rather than an off-site classroom. Together, the portfolio gives contractors a single training partner for hiring, closing, leading, and now, doing all three in a second language.

Remodeling and roofing company owners weighing whether to build or expand a bilingual sales team typically start with a conversation about where the current program breaks down. Grosso University’s team, led by Dominic Caminata and supported by Wendy Harmeyer’s Spanish Development track, walks contractors through what On-Site Training would look like for their specific market, service mix, and existing sales staff. A client considering the investment often asks a version of one more testimonial’s language: “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.” That is the standard the Spanish curriculum was built to match, not approximate.
