Meet the Team

Mark W. Simpson, Founder and President

Mark has never been known to include a suit, tie or briefcase in his daily wardrobe. He excels in work boots, a hard hat and safety shirts.

Mark grew up in a small-town west of Ottawa Ontario, where he developed an interest in the landscaping and construction world. At the age of 16, he worked for various companies and continued to the years following.

At 19 years old, he decided to start his own business; MWS construction. He started this company based on the need to have the control he desired and required to operate a successful business. This business caries the same values and roots he was raised and instilled with: hardworking, honesty, respect, pride, loyalty and a very high attention to detail.  The quality of every project he completes is done in an obsessive nature and ability to produce the highest quality of performance.

It is a 24 hour a day; 7 days a week; 365 days a year ritual at MWS to do things once and do it right.

MWS Construction has grown from a pickup truck with a trailer and one employee, to ten employees, multiple pieces of modern and up to date, heavy equipment and vehicles that he takes much pride in. With over 10 years’ experience and thousands of exceptionally well satisfied customers is the proof that MWS Construction delivers. Their testimonials outlining the impressive project results provide the fuel to

Drive Mark and his company to continue in this tradition of pride and excellence.
