LEADERSHIP
NuBuild has been growing and expanding North Americas telecommunications infrastructure for 10 years.
Our founder and CEO Angelo Guerriero didn't stumble into infrastructure, he built his way into it. With a proven track record in heavy civil construction, growing and successfully exiting his own business, Angelo brought that same entrepreneurial sharpness to NuBuild when he founded it in 2016.
Umberto and Michael, both civil engineers, lead the company together with Angelo. Their technical foundation combined with Angelo's business instincts created something rare in this industry: a company that understands the work from the ground up, and runs it with the discipline of a seasoned operator.
Since 2016, that combination has grown NuBuild into a team of 150+ employees, a fleet of 300+ machines, and an operation that now spans both Canada and the United States.
One Family. One Vision. One standard.
The NuBuild Way.

THE EXECUTIVE TEAM

President
Angelo Guerriero
Angelo brings over 40 years of experience in heavy civil and construction to his role as President of NuBuild Contracting. Before founding NuBuild, he built and led successful construction businesses; a track record that shaped the leadership philosophy and operational standards the company runs on today. Ten years into NuBuild's journey, Angelo remains deeply involved in both the big picture direction and the day-to-day of the business. His hands-on approach and decades of industry knowledge continue to be the foundation the entire organization is built on.

Senior Vice President
Umberto Guerriero
Umberto is a Certified Engineering Technologist with 15 years of experience in civil engineering, and one of the original architects of what NuBuild is today. Before co-founding the company, he served as an inspector with the Municipality of Durham and went on to work as a construction manager. This experience gave him a deep understanding of how projects are built, managed, and delivered at every level. At NuBuild, Umberto has been involved in the company's processes from day one, and his technical precision and operational instincts remain central to how the business runs.

Operations Manager
Michael Guerriero
Michael is a Certified Engineering Technologist with 10 years of experience in civil engineering. He joined NuBuild in 2018, bringing a background in land development technology that gave him a strong foundation in how projects take shape from the ground up. As Operations Manager, Michael is focused on the successful execution of day-to-day operations & making sure the right resources, processes, and people are in place to keep projects moving and standards high.

Chief Financial Officer
Anna Marchese
Anna has spent over 40 years in accounting and finance, managing the financial operations of multiple businesses — including family-owned enterprises and the construction companies that preceded NuBuild. That level of experience across industries and business structures gives her a uniquely grounded perspective on how organizations grow and sustain themselves. She has been with NuBuild from its very first day, and her financial stewardship has been a quiet constant behind every milestone the company has reached. Outside of NuBuild, Anna is also a registered real estate salesperson — a reflection of the same sharp eye for value and long-term thinking she brings to everything she does.

Director of Operations
Mike Pothier
Mike spent 31 years with the Ontario Provincial Police, rising to the rank of Detective Inspector and serving as a Major Case Manager. These are roles that demanded precision, leadership under pressure, and the ability to coordinate complex operations with zero margin for error. After retiring from the OPP, he transitioned into private corporate investigation before joining NuBuild in 2023 as an Operations Manager. His impact was immediate. In 2024, Mike was promoted to Director of Operations, and the organization he oversees runs like a well-oiled machine — structured, accountable, and built to perform.

Director of Marketing
Alexander Russo
Alex's foundation in advertising and marketing was built in the classroom and sharpened quickly in the field, starting with an internship in advertising before launching a media company in 2017 focused exclusively on real estate and construction. That company grew, earned publication features in industry magazines, and is still in operation today. After two years working with NuBuild as a client, Alex joined the team full-time as Director of Marketing — bringing the creative instincts, industry fluency, and entrepreneurial edge of someone who has built something of their own.

Senior Manager, Design
Daniel Cain
With nearly 15 years in the telecom industry, Daniel has built a career spanning roles from CAD Technician to Senior Manager, understanding the challenges in each role from first hand experience. Daniel has led design and permitting project teams across Canada, while building collaborative client relationships and partnerships with local contractors along the way.
At NuBuild, Daniel brings a steady hand, sound decision making, and over a decade of management experience to our design team. With a strong focus on health and safety, a client and quality first approach, and an eye for budget conscious solutions that get it right the first time, Daniel is focused on delivering repeatable success for every project.
