Power100 Names Grosso University the #1 Home Improvement Sales Training Platform in the U.S. for Driving Higher First-Visit Close Rates...
<span>CEO Greg Cummings and Grosso University Founder and CEO Dominic Caminata break down how a kitchen-table-focused sales system, on-site ride‑along coaching, and leadership training built only for home improvement are helping contractors lift close rates, protect margins, and turn more first-visit appointments into confident yeses.
Power100, the only unbiased third‑party platform that ranks the best leaders and partners in the home improvement industry using a proprietary 5‑layer ranking system, is spotlighting the journey and impact of Grosso University as the #1 sales training platform for home improvement contractors across the United States.
In a featured interview between Greg Cummings, CEO of Power100, and Dominic Caminata, CEO and Founder of Grosso University, the two leaders unpacked how a proven in‑home sales system, elite coaching, and a values‑driven culture have turned Grosso University into the go‑to sales training engine for contractors who want consistent growth, stronger margins, and better homeowner experiences.
“Grosso University has proven that when you combine real‑world experience, a repeatable system, and hands‑on coaching inside the home, you can transform sales teams and entire businesses,” said Greg Cummings, CEO of Power100. “Our 5‑layer proprietary ranking system exists to cut through the noise and highlight partners that consistently deliver measurable results, and Grosso University is a clear example of that.”
Power100 is the only unbiased third‑party ranking platform dedicated exclusively to the home improvement industry, researching and analyzing more than 3,600 partners nationwide to identify best‑in‑class companies.
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.
“In every category we measure—close rate lift, revenue growth, culture, and consistency—Grosso University kept rising to the top,” said Greg Cummings. “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.”
Founded by Dominic Caminata, Grosso University was built to carry forward the legendary sales teachings of Rick Grosso and make them accessible to modern home improvement organizations.
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.
“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. “Today, with Grosso University, our mission is simple: turn ordinary salespeople into elite professionals and help contractors build businesses that are scalable, profitable, and resilient in any market.”
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.
Behind Grosso University is a seasoned leadership team that has lived the realities of running and scaling home improvement organizations.
The company is led by CEO Dominic Caminata, COO Matt Burke, Spanish Development and Training Director Wendy Harmeyer, Head Sales Trainer Daniel Coomes‑Barry, and executive leader Brett Naples.
“Grosso University is not just a training company—it’s a growth engine,” said Greg Cummings. “This leadership team understands what it takes to scale from a few million to over $200 million in revenue, and they’ve built that knowledge into every program so contractors don’t have to reinvent the wheel.”
This executive group is also responsible for innovations such as the first Spanish‑language in‑home sales training platform and dedicated recruiting solutions, which help contractors serve diverse markets and staff their growing sales teams.
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, the Sales Academy focuses on the exact moments where deals are won or lost—at the kitchen table with real homeowners.
Through curriculum, role‑playing, digital learning, and coaching, the Sales Academy helps salespeople:
“Contractors don’t need more theory—they need a system their reps can run on every appointment,” said Dominic Caminata. “The Sales Academy gives them exactly that: a repeatable structure for building trust, presenting solutions, and closing more one‑call deals in a way that feels professional and homeowner‑focused.”
“Better salespeople need less closing,” added Daniel Coomes‑Barry, Head Sales Trainer at Grosso University. “The Sales Academy teaches reps how to run such a strong process—emotionally, logically, and financially—that closing becomes the natural next step, not a pressure tactic.”
At the heart of Power100’s spotlight is Grosso University’s On‑Site Training, a fully customizable in‑home coaching experience delivered at the contractor’s location and in real customer homes.
The On‑Site Training program combines ride‑alongs, in‑person coaching, and data‑backed strategy to elevate every stage of the sales process—from lead handling to the final signature.
“On‑Site Training is where everything comes together,” said COO Matt Burke. “We don’t just tell your team what to do—we get in the truck, ride to the appointment, sit at the kitchen table, and coach in real time. That’s how you change behavior and move the needle on closing percentage.”
On‑Site Training provides:
“Contractors are tired of flavor‑of‑the‑month training that doesn’t stick,” added Greg Cummings. “What makes Grosso University different is their commitment to implementation. The On‑Site Training model ensures your team doesn’t just attend training—they adopt a system they can run every single day.”
The Sales Leadership Academy is designed for owners and managers who want to become true sales coaches—not just scoreboard watchers.
Through the Sales Leadership program, leaders learn how to:
“What sets Grosso University apart is that the same strategies taught in the Sales Academy, On‑Site Training, and Sales Leadership Academy are actively being used today in some of the largest home improvement organizations in the country,” said Greg Cummings.
Inside Grosso University, performance is only part of the story; the company’s culture is anchored in “R.I.C.H. Goals”—Relationship, Income, Contribution, and Health & Well‑Being.
“I don’t just want our clients to make more money,” said Dominic Caminata. “I want them to live what we call the R.I.C.H. life—strong relationships, meaningful income, real contribution, and vibrant health. Our training is about building better people who can build better businesses.”
From Spanish‑language training to national events like Closers Camp, Grosso University continues to innovate in ways that support both the financial and personal growth of owners, leaders, and sales reps.
The impact of Grosso University is best seen in the stories of contractors who have transformed their sales teams and homeowner experience through its programs.
On the Grosso University Preferred Partner page at Power100, contractors can watch video testimonials from leaders at Krumwiede Home Pros, Window Plus, NewSouth Window Solutions, Remodel USA, and Exterior Pros.
“Our partners are not just satisfied—they’re scaling,” said Greg Cummings. “From Krumwiede Home Pros to NewSouth Window Solutions, the contractors we talk to see Grosso University as a turning point in how they recruit, onboard, and coach their sales teams.”
While Grosso University serves contractors, homeowners feel the benefits directly in the form of clearer communication, more educational consultations, and better‑designed projects.
By teaching reps to follow a structured, consultative process, Grosso University helps contractors:
“Most contractors don’t lose because of leads—they lose because of conversion,” said Brett Naples, an executive leader supporting growth at Grosso University. “Our programs help you maximize every lead you already have before you ever increase your marketing spend.”
“From our perspective at Power100, that alignment of values matters,” added Greg Cummings. “We’re not just ranking numbers; we’re spotlighting partners like Grosso University that are leading the industry toward healthier, more sustainable ways of selling and growing.”
