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

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.

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.
