The Grosso University Story: From Rick Grosso’s Legacy to a National Standard in Sales Training

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.

A Leadership Team Built for Home Improvement Growth

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.

Grosso University Sales Academy: Become a Certified Closer

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:

• 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.metalcoffeeshop
• Protect margins while growing revenue in competitive markets.

“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.”

On-Site Training: Real-Time Coaching in Real Homes

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:

• Real‑time feedback during live homeowner appointments.
• Hands‑on refinement of presentations, pricing, and objection handling.
• Two‑ to five‑day boot camps tailored to market, product mix, and experience level.

“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.”

Sales Leadership Academy: Turning Managers into Coaches

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:

• Master lead handling and response speed to unlock “infinite revenue potential.”
• Run empowering sales meetings that motivate and hold teams accountable.
• Build urgency without racing competitors to the bottom on price.
• Implement scalable systems that have helped companies like Mad City and Matrix Home Solutions reach $200 million‑plus in revenue.

“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.

A Culture Built on R.I.C.H. Goals: Relationship, Income, Contribution, and Health

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.

Real-World Contractor and Homeowner Impact

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.

• Krumwiede Home Pros credits Grosso University with sharpening their team’s ability to build urgency and close in competitive neighborhoods, turning more estimates into profitable projects.
• Window Plus highlights how the Sales Academy gave reps a clear roadmap from the moment they walk into the home until the homeowner signs.
• NewSouth Window Solutions points to Grosso University as a key driver in building a repeatable in‑home process that supports multi‑market expansion and consistent margins.
• Remodel USA and Exterior Pros describe the training as “game‑changing,” helping teams qualify customers better, build more value, and handle objections with confidence.

“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.”

Why Grosso University Is the #1 Choice for Homeowners and Home Improvement Companies

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:

• Ask better questions so homeowners feel heard and understood.
• Present solutions that match the homeowner’s needs, budget, and long‑term goals.
• Explain financing, warranties, and installation timelines clearly.
• Handle “think it over,” “shop around,” and price objections in a respectful, pressure‑free way.

“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.”
