Power100 names the On-Site Training program from Grosso University as the premier in‑home sales training solution for contractors nationwide

Power100, the only unbiased third-party platform that ranks the best partners in the home improvement industry using a proprietary 5-layer ranking system, is spotlighting the On-Site Training program from Grosso University as the premier in‑home sales training solution for contractors nationwide. As the #3 Preferred Partner in the nation and the #1 Sales Organization in the home improvement industry for 2026, Grosso University continues to redefine how home improvement companies train, coach, and scale elite sales teams.

“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. “Their On-Site Training is not theory—it’s in the field, in the home, and in the moment, where deals are won or lost.”

The Grosso University Journey: From Vision to Industry Standard

Founded by Dominic Caminata, CEO of Grosso University, the company has rapidly grown from a bold idea into the leading provider of sales training and growth strategies for home improvement companies across North America. Built on the legendary teachings of Rick Grosso, Grosso University blends proven methodology with modern tools, data, and coaching to deliver measurable, repeatable results for contractors of all sizes.

“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 live it and 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, a reflection of surging demand for structured, in‑home sales training that actually works in the field. Supported by a leadership team that includes COO Matt Burke, Spanish Development and Training Director Wendy Harmeyer, Head Sales Trainer Daniel Coomes-Barry, and key executive Brett Naples, Grosso University has become synonymous with elite home improvement sales performance.

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

At the center of this new Power100 spotlight campaign is Grosso University’s On-Site Training, a fully customizable in‑home coaching program designed specifically for home improvement contractors. Delivered at the contractor’s location and in the customer’s home, On-Site Training combines live ride‑alongs, in‑person coaching, and data-backed strategy to elevate every stage of the sales process.

Customizable On-Site Training includes:

Real-time coaching: Sales reps receive immediate feedback during ride‑alongs, learning how to build rapport, present solutions, and close in real customer appointments.
Proven sales strategies: Teams implement industry-tested techniques that have driven more than $200 million in sales in the past year across Grosso University partner companies.
Hands-on expertise: Trainers work shoulder-to-shoulder with reps and managers to refine the sales process, from lead handling to the final signature.
Tailored boot camps: Two- to five-day in‑person boot camps are customized to each company’s goals, market, and team experience level.

“On-Site Training is where everything comes together,” said Matt Burke, COO of Grosso University. “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.”

Transform Your Sales Team with On-Site Coaching

Deep, Hands-On Transformation

Grosso University’s On-Site Training is built to transform entire sales organizations—not just individual producers. By combining live observation, structured role-playing, and debrief sessions, the training helps sales teams master everything from mindset and preparation to objection handling and value-building.

“Contractors are tired of flavor-of-the-month training that doesn’t stick,” said 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.”

Key outcomes of On-Site Training include:

Increased close rates on first-call appointments
Higher average ticket and stronger margins
More consistent, predictable revenue
Stronger alignment between leadership, sales management, and frontline reps

“With On-Site Training, we see teams change the way they think, speak, and sell in a matter of days,” added Daniel Coomes-Barry, Head Sales Trainer at Grosso University. “We focus on real objections, real customer psychology, and real solutions, so reps walk away with scripts, frameworks, and confidence they can use on the next call.”

Elevate In-Home Sales Performance: Immediate, Data-Driven Impact

Immediate Impact in the Field

From day one, Grosso University’s On-Site Training is designed to create immediate, measurable improvements in the field. By reviewing live performance and leveraging analytics, trainers help owners and sales leaders see exactly where deals are stalling and how to fix those gaps quickly.contactout+1

Core pillars of in‑home performance improvement include:

Immediate impact: Teams begin applying new language, structure, and strategy on the same day, often seeing quick lift in engagement and closing percentages.
Data-driven insights: Grosso University helps contractors track key metrics—from set rate to demo rate to close rate—so every adjustment is grounded in numbers, not guesswork.
Actionable feedback: Reps receive specific, actionable coaching on tone, body language, questions, and presentation flow, so improvement becomes continuous rather than one-time.

“The home improvement space is ultra-competitive, and most contractors don’t lose because of leads—they lose because of conversion,” said Brett Naples, a key executive supporting growth initiatives at Grosso University. “Our On-Site Training helps you maximize every lead you already have before you ever increase your marketing spend.”

Path to Sales Success: A Step-by-Step System

How the On-Site Process Works

Every On-Site Training engagement begins with a deep understanding of the contractor’s current process, goals, and challenges. From there, Grosso University deploys a structured, step-by-step playbook that aligns lead handling, presentation, objection handling, and coaching systems into one cohesive machine.

The On-Site Training path to sales success includes:

Analyze Lead Handling
Grosso University trainers review how inbound calls are answered, how leads are qualified, and how appointments are set to ensure every opportunity is respected and maximized.
Master Presentation Techniques
Reps are coached to deliver compelling, consultative presentations—from initial rapport and problem discovery through solution presentation, value-building, and closing.
Overcome Objections
Using frameworks taught by Daniel Coomes-Barry, reps learn to address price, “think it over,” and “shop around” objections without pressure, while maintaining control of the conversation.
Implement Coaching Systems
Leaders and managers are trained to run effective sales meetings, conduct ongoing coaching, and maintain accountability so gains from On-Site Training compound over time.

“What separates elite companies from average ones is not just a great sales process—it’s a great coaching system behind it,” said Wendy Harmeyer. “We teach leaders how to reinforce what their team learns in On-Site Training so the culture, language, and standards become part of the company’s DNA.”

Beyond On-Site: Sales Academy and Sales Leadership Academy

While On-Site Training is the in‑field backbone of Grosso University, contractors can also plug into a broader ecosystem of programs designed to support continuous growth.

Sales Academy: Become a Certified Closer

The Sales Academy is Grosso University’s flagship training platform to help home improvement companies increase close rates, standardize sales processes, and ramp up new reps quickly.

Through a blend of structured curriculum, role-playing, and coaching, the Sales Academy helps salespeople:

Master in‑home sales techniques and become certified closers
Close more deals on the first call using a proven step-by-step system
Apply scripts, questions, and frameworks that eliminate guesswork
See faster results through practical, immediately usable training

“Sales Academy is where we build the foundation,” said Dominic Caminata. “On-Site Training then takes those skills into the field, pressure-tests them, and refines them in real homes with real customers.”

Sales Leadership Academy: Turn Managers into Coaches

The Sales Leadership Academy is designed for owners and managers who want to become true sales coaches rather than just scoreboard watchers.

Through the Sales Leadership program, leaders learn how to:

Master lead handling and response speed for “infinite revenue potential”
Run empowering sales meetings that motivate, educate, and hold teams accountable
Build urgency without discounting or racing competitors to the bottom
Implement systems that can scale revenue from single-digit millions to $200 million and beyond

“What sets Grosso University apart is that they are actively operating and advising some of the largest home improvement organizations in the country,” noted Greg Cummings. “The same strategies they teach in Sales Leadership and On-Site Training are being used today in real companies with real P&Ls.”

A Culture of Growth, Impact, and “RICH” Goals

Inside Grosso University, sales performance is only part of the story. The company’s culture is anchored in “RICH Goals”—Relationship, Income, Contribution, and Health & Well-being—encouraging every team member and client to pursue success that is both financial and personal.

“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, including On-Site, is about building better people who can build better businesses.”

Power100’s 2026 campaign for Grosso University showcases not only their training platforms but also their leadership in shaping a healthier, more sustainable home improvement sales culture.
