Plenty of Change, but Tessier’s Stands Strong at 100 – The Daily Republic

Tessier’s Inc., a Premier Mechanical Contractor serving the Midwest Region, is celebrating their 100th anniversary as a South Dakota business.

Serving Customers in South Dakota for over 100 Years

“We are celebrating our proud South Dakota heritage, our dedicated great employees and their families without whom we would not exist, our customers who have trusted us with their building projects, their needs of specialty metal fabrication and installation, the servicing and maintenance of their mechanical equipment for over a hundred years, and our business partners who have trusted, supported, and encouraged us for all these years,” said Gopal Vyas, chairman of Tessier’s Inc., and a 42-year veteran of the company.

Tessier’s Inc. is a mechanical contractor and sheet metal fabrication company providing heating, ventilating, air conditioning, and environmental control services from their offices in Mitchell, Sioux Falls, Rapid City, and Brookings, South Dakota and Sioux City, Iowa. The company has worked on many highly visible construction projects in South Dakota and in many other states. Tessier’s highly trained and acclaimed service, maintenance, and environmental control experts proudly serve the region. The specialty fabrication and welding division provide services to many industrial clients.

Tessier Sheet Metal Works was conceived when Roy Tessier decided to start a roofing and sheet metal business in Mitchell, South Dakota in 1919.

Evan Tessier followed in his father’s footsteps after World War II and joined the company in 1946. Soon after, Evan decided that the future of the business lay in heating and air conditioning and changed the course of Tessier’s, becoming a Premier Lennox Dealer with the mission of “Making your comfort our concern.” With growth came the incorporation and Tessier Sheet Metal Works was incorporated in 1958.

In 1983 the corporation’s name was changed to the current name of Tessier’s Inc. which was more in line with the current business. Evan’s desire of succession planning lead to key employee buyout to the new generation of owners that included, Doug Splitt, Duane Miller, Bob Wermers, Mark Buche and Gopal Vyas. Mark Buche and Gopal Vyas continued to grow the company and built a reputation based on the finest workmanship, attention to the customers needs, dedication to service, ethics, and relationships. Under the leadership of Buche and Vyas the company opened business offices in Omaha, Nebraska and Rochester, Minnesota. With the offices in South Dakota, Minnesota and Nebraska, it was able to better serve clients in their trade area.

In 2007, Tessier’s Inc. became a part of APi Group, Inc., a multibillion-dollar parent company of more than 40 independently managed specialty construction and infrastructure companies with similar ethics, values, and culture. APi Group, Inc. is based in New Brighton, Minnesota.

In 2010, Mark Buche retired after 37 years of service to the company and Rashid Kadir a 25 year veteran was selected President, along with Mike Wagner (32 years) as V.P. and Darren Brewster (16 years) as CFO to lead the company into the new century.

“For 100 years Tessier’s Inc. has been a big part of the South Dakota construction industry. We are proud of our employees, their dedication and work ethics, and are excited for the next opportunity and for new challenges with our mission of Building Partners One Relationship at a Time. The future is bright with our young and talented leadership team led by President Rashid Kadir,” said Gopal Vyas, chairman of Tessier’s Inc.
