Home improvement companies often spend the most time training the newest people on the sales team. New reps learn the sales steps, practice answering questions, and work on closing a job. But as people gain experience, training can start to slow down. Some sales leaders may feel they already know the process. Others get busy managing people and stop working on their own skills. That creates a real challenge. A sales team cannot keep getting better if its leaders stop learning.
At Grosso University, CEO Dominic Caminata has helped build a place where experienced sales leaders, managers, contractors, and new reps can keep learning together. Through home improvement sales training for contractors, Grosso University gives teams a system they can take back to their companies, practice with their people, and keep using as they grow.
That long-term value stood out during Grosso University’s Closer’s Camp, where Greg Cummings, CEO of Power100, spoke with Mike Biondino, Sales Manager at CAT Exteriors. Mike has known the Grosso organization for years. He has watched Dominic Caminata grow as a leader. He has watched Grosso University grow into a larger training platform. Yet Mike still comes back to the in-person events.
His reason was simple. “I’m always learning,” Mike said.
He explained that as his team grows, he keeps looking for ideas they can take home, put into action, and use to help more people grow into stronger sales professionals and leaders. His experience shows why one call close training for home improvement sales teams can be more than something a new rep learns once. It can become a system that grows with the company.
Power100 was at Closer’s Camp to hear those stories directly from the contractors and leaders who have worked with Grosso University and Dominic Caminata. Power100 is the only unbiased third-party platform that recognizes and elevates the top leaders and most impactful companies in the home improvement industry.
Through conversations like the one between Greg and Mike, Power100 gives the industry a closer look at what contractors are learning, what they are putting into practice, and why experienced leaders continue to invest in their people. Mike’s story points to a simple lesson for growing companies. Great sales leaders do not reach a point where learning stops. They keep looking for better ways to coach their teams, strengthen their process, and prepare the next group of leaders.
At the end of day one at Grosso University’s Closer’s Camp, Greg Cummings connected with Mike Biondino, Sales Manager at CAT Exteriors, to look beyond the lessons taught inside the room. Mike has been around the Grosso system for years. He knew Dominic Caminata before Grosso University became what it is today. He has also had the chance to take ideas from the training and watch members of his own team use them. That history gave Mike a rare view of the bigger picture. His comments were not only about one event. They showed what can happen when a sales leader keeps learning, keeps bringing lessons back to the team, and stays close to a training system as both the company and its people grow.

For Mike, years of sales experience have not given him the sense that he has learned enough. They have done the opposite. The more responsibility he takes on and the more his team grows, the more he sees a need to keep sharpening his own skills.
“I go way back with them and in my infancy of my career, so I just love supporting it and I’m always learning,” Mike told Greg.
That sentence explains much of why Mike continues to return.
Early in a sales career, training may focus on learning what to say in the home. Later, the same lesson can take on a new meaning. A manager may hear it and think about how to coach a rep. A sales leader may think about how the whole team can use it. An owner may see how the idea can become part of the company’s culture.
Mike is now looking at training through that wider lens.
“As we continue to grow, I’m always seeing what else that we can take and implement with the team and just continue to grow,” he said.
The word “implement” matters. Mike is not coming back only to hear good ideas. He is looking for something useful enough to take home.
That is also what makes sales leadership coaching for home improvement companies different from training aimed only at new reps. Leaders must understand the sales process well enough to teach it, monitor it, correct it, and help others get better at it.
Mike’s return to Grosso University shows that learning can change as the leader changes. What helped him earlier in his career can now help him develop someone else.
See how Grosso University helps home improvement sales leaders keep developing their teams.
Mike’s view of Dominic Caminata goes back much further than the current Grosso University campus.

Grosso University, CEO Dominic Caminata
When Greg asked what it had been like to watch Dominic and the organization grow, Mike went back to their first meeting.
“I first met Dom in Virginia with Rick and I’m like, I’m going to get that guy,” Mike recalled.
There was competition in that first impression.
Mike saw someone he wanted to beat.
He then watched Dominic go on to win Grosso that year. From there, Mike continued following what Dominic was doing and how he was applying what he had learned.
“Since I’ve just followed him and, you know, seen what he’s doing in a whole different market,” Mike said.
That history gives Mike’s view of Dominic more weight.
He did not first meet Dominic as the CEO standing at the front of a university. He remembers him doing the work inside the same sales world. He saw the competitive side. He saw the growth. Years later, he is seeing what happened when that experience became something other sales teams could learn from.
That is an important part of Dominic’s story.
Credibility in home improvement sales training for contractors is stronger when the person teaching the system understands what it feels like to use it in the real world. Mike had the chance to watch Dominic go down that path before watching him lead an organization built to help others do the same.
The relationship also says something about growth.
The person Mike once looked at as competition became someone whose work he continued to follow. Today, Mike brings his own team into an environment that Dominic helps lead.
That is a very different kind of win.

A speaker can make people excited.
But Mike pointed to a harder test. What happens after the team goes home?
While talking about his years around the Grosso system, Mike explained that one of the things he has enjoyed most is seeing his own people use what they learn.

Greg Cummings interview with Mike Biondino, Sales Manager at CAT Exteriors
He described being able to “watch my guys implement some of the stuff and grow.”
That takes the conversation beyond whether Mike personally likes Grosso University.
He is watching the ideas reach his team.
For a sales manager, that matters because training has little value if it stays inside a notebook. The goal is for the rep to use it when a real homeowner asks a hard question, when price becomes a concern, when trust has not yet been built, or when the salesperson needs to slow the conversation down.
The Grosso system gives teams a set process to return to. The 11 Step in-home selling system for contractors is designed to help salespeople understand where they are in the conversation and what needs to happen before moving forward.
That structure also gives managers something they can coach.
Mike can return from an event with the same language his team has heard. He can watch how a rep uses the process. He can see where the rep is strong. He can also see where the rep needs more practice.
That creates a bridge between an event and everyday coaching.
It also helps explain why Mike keeps showing up instead of simply sending other people. When the manager understands the training, the lesson has someone inside the company who can keep it alive.
The event may end.
The coaching does not have to.
Greg also asked Mike about something that could be seen all around them at Closer’s Camp: the Grosso University facility itself.
Mike’s response was immediate.
“The facility is just magnificent,” he said.
The comment was lighthearted at first, with Mike joking that he was disappointed his picture was not on the wall yet. But his answer soon moved into a much bigger point about the home improvement industry.
“The industry does need it because I think within us, we do need that platform that everybody can go to that gets that one call close,” Mike said.
That point helps explain why the setting matters.
Home improvement selling has its own challenges. The salesperson often enters a customer’s home. Trust must be built quickly. Needs have to be understood. Value has to be clear before price becomes the main focus. Questions and concerns must be handled without rushing the homeowner.
Mike believes the industry benefits from having a place built around those real situations.
For contractors seeking home improvement sales training in Windsor, Wisconsin, the Grosso University campus provides teams a place to practice those skills with people who understand the home improvement sales process.
Mike also pointed back to one of the oldest ideas in the system.
“That one call close. That’s still back in the day training,” he said.
His point was not that sales should stay stuck in the past.
The tools around a salesperson may change. Lead sources can change. Technology can change. The way customers research companies can change.
But a rep still has to sit with a homeowner and have a real conversation.
That is why one call close training for home improvement sales teams can still matter. The goal is not simply to make a sale as fast as possible. It is important to know how to build trust, explain value, understand the customer, answer concerns, and help the homeowner make a clear decision during the visit.
For Mike, having a place where teams can keep working on those basics fills a need that has not gone away.

As the conversation moved toward the future, Greg asked Mike what excited him most about the next six to eighteen months.
Mike did not start with a sales target.
He started with people.
“Just the growth that I’m going to see in our team,” he said.
He then pointed to something even bigger.
“Watch your new guys kind of grow into leadership and all that.”
That answer brings Mike’s whole view of training together.
A new rep may walk into a training program trying to become better at selling. With enough learning, practice, and support, that same person may later become someone another rep looks to for help.
Mike is excited to see that change happen within his team.
That makes sales manager training for home improvement companies about more than stronger numbers. It can also help companies build people who are ready to coach, lead, and carry the system forward.
Greg then asked Mike what he would say to contractors or salespeople who are not feeling as hopeful about the future.
Mike answered with a situation that almost every home improvement salesperson can understand.
“You can show up to a house and you can go, ‘Oh man, that’s going to be a $50,000 dollar deal,’ and talk yourself out of it,” he said.
The homeowner has not said no.
The presentation has not happened.
The salesperson has simply looked at the size of the job and decided what the customer will think.
Mike believes that it can become its own barrier.
“So it’s the mind. You just got to get over it,” he said.
It was a short statement, but it carried a bigger lesson.
A sales process can give a rep steps to follow. A trainer can teach the questions. A manager can coach the presentation. But the salesperson still has to walk into the home believing there is an opportunity worth earning.
That is where skill and mindset meet.
Mike’s outlook on the future reflects the same belief that keeps bringing him back to training. There is always another lesson to learn. There is always another person who can grow. And there may be more opportunities in front of the team than they first believe.
Mike Biondino’s long relationship with Grosso University gives one view of its impact. He has watched Dominic Caminata grow, watched his own people use the training, and has continued to come back as CAT Exteriors has grown. But that contractor experience is not the only sign that Dominic and Grosso University are gaining ground. Over the past year, both the leader and the organization have earned recognition that points to a larger story about the place they are building in the home improvement industry.

Dominic Caminata was named a Business Elite 40 Under 40 honoree
One of the biggest moments came in May 2026, when Dominic was named a Business Elite 40 Under 40 honoree. He received the honor at the St. Regis New York as part of a group of young leaders recognized for leadership, innovation, and business impact. For Dominic, the award marked more than a personal career milestone. It reflected the work behind building Grosso University from a sales training idea into a national platform serving contractors and sales teams.
That recognition also came during a year when Grosso University reached major industry milestones. The organization was named the number 1 Sales Training Organization for home improvement contractors in 2026 and was also recognized as the number 3 Preferred Partner nationally. Those rankings put the platform Dominic leads among the most recognized resources serving contractors across the country. They also add another layer to what Mike described in his interview. Contractors are not only returning because of relationships. The organization itself is earning broader recognition for the systems, leadership, and value it brings to home improvement companies.
Dominic has also continued taking his ideas outside the classroom. In a featured interview with Greg Cummings, he shared his vision for Grosso University and explained why he believes strong sales systems must work in real homes, with real customers, and under the pressure contractors face every day. That public conversation gave owners and sales leaders another look at the thinking behind the platform, rather than just seeing the finished training programs.
His role as a Power100 Expert Contributor has further expanded that voice. In his article, “Is One Call Closing Really Dead?”, Dominic argued that the future of one-call selling is not built on pressure. He said it depends on trust, education, clear financing, and a strong process that helps homeowners feel sure about their decision. That message connects closely with the kind of training Mike continues to value. The system may have deep roots, but Dominic is still working to update how those ideas fit modern homeowners and today’s contractors.
Together, these milestones show a leader whose reach is growing in multiple directions. Dominic is building a training company, developing sales leaders, speaking to the wider contractor community, and putting his ideas into public conversations that can help the industry think differently about selling.
For Grosso University, the awards and rankings are not the finish line. They are signs that the work being done inside the organization is being noticed outside it.
That makes Mike Biondino’s words even more meaningful. He has watched the journey from much closer than most. Long before the rankings, the national recognition, and the larger platform, Mike remembers the salesperson he wanted to beat.
Today, he is watching that same person lead a university that his own team continues to learn from.
For Mike Biondino, the value of training has become clearer with time. Years in the industry have not made him feel finished. They have shown him that every new stage of growth brings a new lesson, a new challenge, and another person who may need help becoming better.

Grosso University Closers Camp
That is what makes his long connection with Dominic Caminata and Grosso University stand out. Mike has seen the journey from many angles. He remembers Dominic as someone he once wanted to beat. Today, he sees him as a leader building a place where sales professionals can keep learning, practicing, and preparing for what comes next.
But the strongest part of Mike’s story is not how long he has known the organization. It is what he continues to do with what he learns. He brings ideas back to his team. He watches newer salespeople develop. He sees people take on more responsibility. And he looks forward to seeing some of those same people grow into leaders.
That is a different way to think about experience. Experience does not have to mean knowing everything. It can mean knowing how much there still is to learn.
Mike also left the conversation with a reminder for salespeople unsure about the road ahead. Opportunity can disappear before the homeowner ever says no if the salesperson has already decided what is possible. A large project, a hard conversation, or an uncertain market can make a rep pull back before giving the customer a real chance to decide.
For Mike, the answer starts with the mind. Stay open to the opportunity. Trust the process. Keep working on the skill. Keep learning.
That same idea now sits at the center of what Grosso University represents under Dominic Caminata’s leadership. The goal is not for a salesperson to complete training and move on forever. The goal is to build habits, confidence, and leadership skills that can continue to grow with the person and the company.
Mike Biondino has been around long enough to see how much can change.
He has also been around long enough to know that the people who keep learning are often the ones most ready for whatever comes next.
Power100 researches and compares companies serving the home improvement industry rather than relying solely on marketing claims or paid praise. For its 2026 partner rankings, Power100 says it reviewed more than 3,600 industry partners through its five-layer evaluation system. The platform looks at areas such as company performance, contractor results, customer experience, innovation, operations, and long-term value. That process led Power100 to rank Grosso University as the number 1 Sales Training Organization for 2026 and the number 3 Preferred Partner nationally.
Power100 says its rankings come from an independent evaluation process rather than a paid ranking position. The platform compares companies against thousands of other industry partners before making its selections. In Grosso University’s case, Power100 cites contractor outcomes, client feedback, leadership, company culture, and sales performance as reasons the organization ranked so highly. This gives contractors another source of information when comparing home improvement sales training, rather than relying solely on what a training company says about itself.
No. Grosso University offers programs for both new and experienced sales professionals, as well as separate coaching for managers, owners, and company leaders. Its Sales Academy includes the 11 Step In-Home Selling System, mindset coaching, role playing, private coaching, and ongoing training. The company also offers Sales Leadership Coaching and an Extreme Leadership Mastermind for people responsible for building and leading teams.
Mike Biondino’s experience supports that point. He has been around the Grosso system since early in his career, yet he still returns because, as he told Greg Cummings, “I’m always learning.” His view is that the lesson changes as the person grows. A salesperson may first learn how to sell. A manager may later use the same system to coach someone else.
The goal of Grosso University’s one-call close training for home improvement sales teams is to give salespeople a clear process for handling the full in-home conversation. Its training covers presentation skills, rapport, product value, objection handling, mindset, and closing techniques. The company describes its Sales Academy as a way to improve first-call close rates through training, role-playing, coaching, and repeatable sales methods.
Mike’s comments also point back to the basics of knowing how to work through the entire appointment, rather than deciding too early that a homeowner will not buy. His message was simple: give the opportunity a real chance before talking yourself out of it.
Grosso University offers more than a single event. Its current programs include ongoing coaching, private Zoom sessions, role playing, management meetings, online training resources, leadership coaching, and longer-term sales operating systems. Its Grosso OS program, for example, includes rep certification, custom sales systems, live training, retraining, performance correction, and leadership coaching over time.
That helps answer one of the biggest concerns with sales training: whether the lessons survive after the event ends. Mike Biondino said he looks for ideas his team can “take and implement.” He has also watched his own salespeople use lessons from the training and grow, which is why continued practice matters more than simply attending.
Grosso University provides on-site sales training for contractors that goes beyond classroom instruction. Its On-Site Training program includes custom boot camps lasting two to five days, hands-on coaching, ride-along training, real-time feedback, lead handling reviews, presentation coaching, objection training, and systems managers can continue using afterward.
Closer’s Camp follows a similar practice-based approach. The 2026 event used live sales challenges, competition, and real-world practice instead of a sit-and-listen format. Mike’s focus on bringing lessons back to CAT Exteriors fits that model because the value is meant to show up in what a salesperson can actually do after the training.
Yes. Grosso University has programs built specifically around leadership. Its sales leadership coaching for home improvement companies covers recruiting, onboarding, lead management, accountability, financial programs, operations, team culture, and strategic growth. The company also teaches managers how to move beyond simply tracking numbers and become better coaches for their salespeople.
That part of the platform connects directly to Mike Biondino’s Outlook. When Greg asked what excited him about the future, Mike spoke about watching new people on his team grow into leadership. In his view, sales development does not end when a rep learns how to close. The next step is helping that person become capable of leading others.
No. Grosso University operates its campus in Windsor, Wisconsin, but it also provides virtual and company-based training options. Closer’s Camp 2026 offered virtual streaming for people who could not attend the live event, while other programs use Zoom coaching, online training, virtual ride-along options, and customized training delivered directly inside a contractor’s company.
That means contractors searching for Grosso University virtual sales training or nationwide home improvement sales coaching are not limited to attending the Wisconsin campus. The physical facility provides teams with a place to train together, while the broader program allows companies in other markets to continue using the system throughout the year.
