Built to Last: RJ O’Neil Turns 100

SMACNA Greater Chicago is proud to congratulate contractor member RJ O’Neil on reaching an extraordinary milestone: 100 years in business!

Since 1926, RJ O’Neil has delivered quality HVACR, plumbing, pipefitting and maintenance services across healthcare, commercial, industrial and institutional sectors. Their longevity is no accident, it’s the product of an unwavering commitment to integrity, craftsmanship and the kind of lasting client relationships that define true excellence in our industry.

“Reaching 100 years is a significant milestone that reflects the strength of our team, the trust of our clients and the value of our partnerships,” said Jessica Medrano, CEO/President. “The relationships we have cultivated over generations are central to our success. While we take great pride in our history, we are equally focused on the opportunities that lie ahead.”

True to that commitment, RJ O’Neil will celebrate throughout the year with employee recognition initiatives and community programs — honoring a century of legacy while investing in the next.

On behalf of SMACNA Greater Chicago and the entire mechanical contracting community, we extend our heartfelt congratulations to the team at RJ O’Neil. Here’s to the next 100 years!
