Walk into McHenry Pressure Cleaning Systems and you’ll be greeted by Chopper, a stubborn but loveable Chesapeake Bay Retriever. “You don’t negotiate with a Chessie,” says President Dennis Black.

The cute pooch is a new addition to a company with a long history. Black has been working with pressure washers for more than 30 years. At age 18, he began working for a large Maryland auto parts store owned by the McHenry family.

Soon, he and John McHenry realized that pressure washers were a good business on their own. They started a separate pressure cleaning Maryland business and sales began to climb.

In the early days, they had a large agricultural base including dairy farmers, as well as small garages and trucking firms. As technology began to change, so too did their customer base.

“The Internet had a tremendous effect on our business,” said Black. “It increased the awareness of what pressure washers can do; it gave us another tool to get out to our customers.”

Another reason for McHenry’s growth is their partnership with Mi-T-M.

“Bar none, Mi-T-M is the best manufacturer we work with. They always support us and you just don’t find that in our industry,” he said.

Black said he appreciates Mi-T-M’s high-quality equipment, warranties, programs, and the fact they offer him private label machinery. But he especially cites the relationships he’s formed with Mi-T-M staff members.

“Karl Loeffelholz is always helping us, always advocating for us,” he explained. “Karen Anderson has always been very good to me. We have a bond of friendship.”

Like Mi-T-M, integrity has always been the cornerstone of Black’s business.

“At the end of the day, our service and our knowledge is what we have,” he said. “We enjoy helping our loyal customers.”

“Dennis and his team at MPCS is one of our greatest partners in this business. They have continued to support us, not only by purchasing equipment but always giving us feedback on how to improve our products, programs and to become a better manufacturer.” – Karl Loeffelholz, Dealer Division Manager Mi-T-M Corporation
