Enzo USA, Inc. was founded by Mary Jo and Brett Guarrero. In 2006, while raising their now teenage son in the small town of Telluride, Colorado, they partnered with Rovanco Piping Systems as a manufacturer’s representative of their pre-insulated piping systems. In addition to selling Rovanco products, Enzo launched their own line of sensible, thermal efficient products and continues to research, design and develop innovations. In 2016, the Guarrero’s relocated to Broomfield, Colorado, a town sandwiched between Denver and Boulder.

As a business consultant and former VP in the cable TV and wireless industries, MJ has over 30 years of business operations experience.  Her role at Enzo involves finance, marketing, branding and product development. As of 2021, MJ became the sole owner of Enzo, making the organization 100% women-owned.

A Denver native, MJ loves hiking, tennis, soccer (go Man City) and is a proud graduate of Metropolitan State University (go Roadrunners). FAVORITE SANDWICH: North Denver’s finest…grilled Italian sausage patty on a toasted bun, topped with green chilis, provolone and splash of red sauce.

Brett Guarrero’s role at Enzo is everything engineering and sales. Since 2006, he has designed and specified hundreds of miles of insulated piping systems. He can be found on job sites across the country and beyond…from Los Angeles to Pittsburg, Dickenson to Houston, and from Germany to Israel.

In addition to blazing a trail selling Rovanco and Enzo products, Brett is an inventor. To date, Brett has earned two U.S. patents and continues to design unique products and systems for the built environment.

Brett holds degrees in Industrial Engineering, Finance and Marketing from Southern Illinois University, and an MA in Organizational Leadership from Regis University, Denver. He is a native Chicagoan; frequently reverts to speaking in “Guido”; is a private pilot and would love to spend every waking moment outdoors.
