*Required Fields

Employee-ownership means unity. One team, one dream: my colleagues' success is my success, and vice-versa. We have each others' back. Also, I feel like I have a voice. Our opinions matter here!

Janet Perez
Project Manager

We have the horsepower to build just about any project, but how you get to the finish line matters. We believe in a partnership approach with our clients and we work hard to create a positive environment and an enjoyable construction experience.

Sean Jean
Project Executive

At WEO I get to work with some of the best minds in construction. Solving challenges long before putting a shovel in the ground is an extremely satisfying part of our work. Getting to demonstrate our plans to a perspective client is equally rewarding.

Brian Rush
VP, Preconstruction

Being an employee-owner means my opinion matters. It makes us all work harder because we care MORE about the end results. It also means I’m not working for a big, faceless organization. I am working for ME and this team. It means that I get to see my hard work pay off personally.

Melissa Lowry
Project Manager

Thoughtful leadership makes W.E. O'Neil better as a company in that it attracts the smartest and brightest people. People who want to be challenged and want to see their ideas put to use come to work for W.E. O'Neil.

Mike Hockett
Exec VP, Client and Project Development

We strive to be forthright in everything we do. There’s no personal conflict between what my job is asking me to do and what my personal values suggest that I should do.

Project Superintendent

Why W.E. O'Neil

Client Stories

No way did I expect this kind of success on a job. Pandemic? Rain? Tough Site? How about two months early and money back. This is one to remember and celebrate.

James Palda, Senior Director Real Estate Development
Steadfast Development

What specifically sets W.E. O’Neil apart from their competition is their team-oriented approach. They really care about the client.

Jonathan Power
Game Creek Holdings

From our first walk through with W.E. O’Neil’s construction supervisor to final delivery, their team was professional and executed beautifully. We were able to lease nearly 500 units in six months in large part due to W.E. O’Neil delivering an exceptional product on-time and in process. Their high quality delivery of the residential towers surpassed our expectations. W.E. O’Neil’s craftsmanship and efficiency at turnover was best-in-class. I look forward to working with them in the future.

Aaron Galvin
Luxury Living Chicago Realty

We consider W.E. O’Neil to be a partner and one of our few ‘go-to’ contractors on a national basis. We plan to continue to use them and I highly recommend them. They repeatedly showed their willingness to be a partner and team player on each project. Their teams are very strong and were able to identify problems in advance to reduce costly change orders and delays. Whenever there were problems, as there always are in construction, W.E. O’Neil looked for solutions, not excuses. That reflects the quality of their people, who are among the most dedicated and qualified of any we have worked with.

Paul Chapman, Vice President (former)
Belmont Village

O’Neil is made up of a core group of dedicated and competent professionals, who, while moving forward using the latest and most innovative techniques available to successfully guide the completion of a project, do so in a caring and nurturing manner that is almost akin to a parent successfully raising a child. The fact that O’Neil is a employee-owned business is always evident, and it is what their success is rooted to. As DePaul looks forward to its continuing relationship with W.E. O’Neil we absolutely recommend their services to any potential client who has a desire to see its construction project completed on time, on budget, and at a level of quality that is unsurpassed.

Robert Janis, Vice President of Facility Operations
DePaul University

The most valuable service W.E. O’Neil Construction provided for us on this project was in how easy, responsive, and friendly they are to work with. It made problem solving so much more effective.
