Press Release – Organizational Announcement

For Immediate Release



BROOKFIELD (Jun. 5, 2024) – John Muraski has been named President of CornerStone One, a Brookfield-based company that specializes in commercial plumbing, commercial HVAC, earthwork and site utilities servicing Southeastern Wisconsin.

Muraski takes over as President, replacing founder Steve Adkins in overseeing daily operations. Adkins will remain as Principal of CornerStone One, focusing on long-term vision and company strategy.  Jason Pampuch will take on the role of Partner, continuing in his leadership role within the interior plumbing division.

Adkins founded, then CornerStone Plumbing, in 2003 in the garage of his home. The company grew its service offerings to include site utilities in 2005 and later earthwork in 2018. After expanding its services, the company changed its name to CornerStone One in 2018 to better reflect its breadth of work and capabilities. In 2020, the company introduced a commercial HVAC division, making it a full-service commercial site building resource from pre-planning to engineering to implementation.

“Everyone who we have encountered has played a role in building the company to be something I’m extremely proud of,” Adkins said. “CornerStone One was founded on a vision to make integrity, dedication and quality paramount to our business. Building on that foundation, we’ve created a reputation for quality and reliability in plumbing, site utilities, earthwork and HVAC. Each step was a leap towards greater challenges and achievements, underscored by our core values and a relentless pursuit of excellence.”

Muraski (42) joined CornerStone One in 2017 and most recently served as Director of Plumbing. His experience is extensive, from serving his state of Wisconsin Plumbing Apprenticeship shortly after graduating High School, to holding a Master Plumber license today. In his career, Muraski gained expert-level experience in manufacturing, sales and plumbing. Upon joining CornerStone One, Muraski took the lead on projects including St. Camillus Tower, Milwaukee Symphony Orchestra, Komatsu North American Headquarters, Rite-Hite World Headquarters and Baird Center expansion.

“I’m honored to step into the role of President of CornerStone One. While I do have vision and ambitions, I’m eager to carry on the existing values that our company was founded on and practices every day; committing ourselves to excellence in our work and in our community,” Muraski said.

In his years of leading teams, Muraski has developed a leadership style that prioritizes empathy, integrity, humility and work ethic. In his role as President, he plans to continue to support others and help team members grow into leaders themselves.

“John has a natural ability to lead by example,” said Adkins. “He has a unique leadership style and voice that is forward-thinking and inspirational. John takes care of his team members and is a mentor to others. His exceptional leadership qualities and deep operational understanding will take CornerStone One to great places.”

CornerStone One is located at 20865 Enterprise Ave, Brookfield, WI. The company offers services for verticals including healthcare, education, government, hospitality,  manufacturing, apartment/condo living, religious organizations, senior living and more.
