How Power100 and ABC Supply’s College of Knowledge Spotlighted Grosso University as the Best Sales Training Platform

Power100 is the only unbiased ranking platform dedicated exclusively to the home improvement industry, researching and analyzing thousands of partners to identify the very best companies, leaders, and preferred partners. Using its proprietary 5‑layer system—performance metrics, contractor outcomes, innovation, operational excellence, and long‑term value—Power100 identified Grosso University as the top sales training platform for contractors who sell in the home.

At ABC Supply‘s College of Knowledge in Cincinnati, Greg Cummings used the live setting—surrounded by roofing, siding, window, and remodeling contractors—to share why Grosso University earned that recognition. “In every category we measure—close‑rate lift, revenue growth, culture, and consistency—Grosso University kept rising to the top,” he said. “They are not just training reps; Grosso University is installing systems that help contractors grow from a few million in revenue to 200 million dollars and beyond, without losing the homeowner experience.”

By putting this conversation in the middle of ABC Supply‘s College of Knowledge—an event specifically designed to help contractors sharpen their edge—Power100 and ABC Supply underscored that choosing the right sales training partner is as important as choosing the right shingle, skylight, or financing solution.

Why Being an Expert in the Home Matters More Than Ever for Contractors at ABC Supply’s College of Knowledge

The interview between Greg Cummings and Wendy Harmeyer at ABC Supply‘s College of Knowledge centered on a simple idea: homeowners do not need another estimate—they need an expert.

As Wendy Harmeyer explained, homeowners are showing up with more information than ever thanks to the internet, manufacturer sites, and reviews. What they still lack is someone in their home who can inspect, diagnose, and explain trade‑offs in plain language. Grosso University trains sales professionals to be that person: the expert in the home who can look in the attic, walk the roof, review windows or baths, and translate technical details into clear recommendations.

Greg Cummings told the College of Knowledge audience that if contractors want to stand out in markets served by leaders like ABC Supply, they must send “experts, not estimators” into homes. That is why he described Grosso University as “the best sales training platform in the home improvement industry”—because it specializes in training experts for real in‑home situations.

How Grosso University Turns College of Knowledge Insights Into In‑Home Expert Systems

Founded by Dominic Caminata, Grosso University was built to carry forward the teachings of Rick Grosso and adapt them to modern, data‑driven, homeowner‑centric sales. After being named Salesman of the Year at Mad City Windows & Baths, Dominic Caminata set out to build a platform that would let contractors across the country plug into a proven system instead of starting from scratch.

From 2020 to 2021, Grosso University more than doubled its own revenue, reflecting surging demand for real‑world in‑home sales training. Today 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.

At ABC Supply‘s College of Knowledge, Greg Cummings highlighted this leadership team as a key differentiator. He told attending contractors that Grosso University is built by people who have lived through the same struggles as the audience—low close rates, thin margins, inconsistent teams—and who have encoded their solutions into a system any company can adopt.

What Makes Grosso University’s Sales Academy Different From Generic Training

At the heart of Grosso University is the Grosso University Sales Academy, a flagship program that turns sales reps into certified closers using a step‑by‑step in‑home process. Unlike generic sales programs, the Sales Academy is written specifically for home improvement categories—roofing, windows, siding, bath, and full remodeling.

Through curriculum, role‑play, 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 consistent structure.
• Use scripts and questions tuned to home improvement products.
• Protect margins while still winning competitive deals.

“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.”

Head Sales Trainer Daniel Coomes‑Barry added, “Better salespeople need less closing. 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.”

These are the same principles Greg Cummings and Wendy Harmeyer underscored to contractors walking the halls at ABC Supply‘s College of Knowledge: if you want to be the expert in the home, your process must be as strong as your product.

On‑Site Training and Leadership Coaching: Bringing College of Knowledge Lessons Into Real Homes

Beyond the Sales Academy, Grosso University is known for Grosso University On‑Site Training, where coaches come directly into a contractor’s market to ride along on real appointments. On‑Site Training combines live coaching, script refinement, pricing work, and objection handling to translate classroom learning into field behavior.

“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.”

For owners and managers, Grosso University offers the Sales Leadership Academy, which teaches leaders how to manage leads, run effective meetings, build urgency without discounting, and install scalable systems. These leadership systems mirror the themes contractors hear at ABC Supply‘s College of Knowledge—systems, coaching, and culture—and give them a way to implement those ideas once they return home.

“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.

How Wendy Harmeyer and Grosso University Serve Spanish‑Speaking Homeowners Contractors Meet at College of Knowledge

One of the most important parts of Greg Cummings‘s College of Knowledge interview was his conversation with Wendy Harmeyer, who leads Spanish Development and Training at Grosso University.

Wendy Harmeyer explained how Grosso University built the first fully integrated Spanish‑language in‑home sales training platform specifically for home improvement. She trains bilingual reps to deliver the same expert‑level process—inspection, diagnosis, education, and proposal—in Spanish, helping contractors serve growing Hispanic and Latino communities with respect and clarity.

As contractors at ABC Supply‘s College of Knowledge look to expand into new markets and neighborhoods, Grosso University and Wendy Harmeyer offer a clear path to becoming the trusted expert in any home, regardless of language. According to Greg Cummings, this ability to train in both English and Spanish is another reason Grosso University stands alone as the best platform in the industry.

How Grosso University’s R.I.C.H. Culture Aligns With ABC Supply’s Focus on Long‑Term Success

Inside Grosso University, the culture is built around R.I.C.H. Goals—Relationship, Income, Contribution, and Health & Well‑Being. Dominic Caminata often notes that Grosso University is about building better people, not just better pipelines.

That philosophy connects directly with what ABC Supply and Power100 promote through events like the College of Knowledge: long‑term, values‑driven growth. By training reps and leaders to value relationships, sustainable income, contribution to their communities, and personal health, Grosso University helps contractors build companies that homeowners can trust for decades.

Real‑World Results: From College of Knowledge Conversations to Contractor Growth

The impact of Grosso University is visible in the contractors who come to events like ABC Supply‘s College of Knowledge and then implement its systems. On the Grosso University Preferred Partner page at Power100, companies like Krumwiede Home Pros, Window Plus, NewSouth Window Solutions, Remodel USA, and Exterior Pros share how Grosso University has changed their trajectory.

From sharper qualification to better value‑building and more confident objection handling, these contractors validate what Greg Cummings told the College of Knowledge crowd: partnering with Grosso University is often the turning point between flat growth and scalable success.
