Dennis O’Shaughnessy – Founder and President

After 12 years as the Central Regional Sales Manager for PERMA-PIPE, a company that makes pre-insulated piping systems for direct buried, heating and cooling distribution systems, an opportunity presented itself to become the Manufacturer’s Representative for PERMA-PIPE in Illinois, Iowa and Wisconsin. I jumped at the chance to launch my own business. I opened the doors in 1999 and have successfully grown this business building on the industry knowledge of my mentors and fellow workers at PERMA-PIPE and putting that business acumen to good use. I am very proud that I have been able to build a company and hire the right people to make Mechanical Equipment a recognized leader in our market place.


With a degree in Mechanical Engineering Technology, Ed started his career with a small engineering firm working his way from pump design engineer to Vice President gathering valuable experience in design, production, sales and marketing. He then switched to the plumbing side of the business before joining Mechanical Equipment in sales. Our customers (and us) are lucky to have access to his knowledge.


Pat has a long, successful history in the commercial HVAC business. He began as a pipefitter apprentice right out of high school and worked his way up through the ranks quickly, becoming a Superintendent at a major Mechanical Contractor.
