W. E. O'Neil built Desert Bloom Ob & Gyn's beautiful medical office on time and under budget. The building exceeded our high expectations.

Sam C. Baxter, Director Human Services Department City of West Hollywood

WE O'Neil Construction Company recently completed a major renovation and addition project for our Mercedes-Benz of Littleton location. This was a very complex project with many moving pieces that could have had a very different outcome were it not managed so efficiently. Thank you for doing an excellent job of keeping our facility "Open for Business" throughout the construction.

Terry Minnick Mercedes-Benz of Littleton

We would like to thank W.E. O’Neil Construction Company for an outstanding effort on this recently completed project located in the Pacific Corporate Towers Building. The project involved a very aggressive schedule to be completed in three months. As a result of a “total team” effort the project was completed on schedule and within cost without cutting corners or a reduction of the quality of workmanship

Gerald Anderson, Facilities Project Mgr The Boeing Company.

W.E. O’Neil’s building team was great! They were aware of our financial structure and focus on cost efficiencies without compromising value and quality in delivering an exceptional project.

Kathy Luna, Owner Boys & Girls Club of Metro Denver

The Rincon Tower Expansion was an overwhelming success on all facets. Fast track, escalating materials cost, design in progress or complete lack of design did not stop the momentum. Quality subcontractors helped in a big way. The focus on maintaining cost and schedule momentum was imperative on this project. All the hard work paid off, ahead of schedule and under budget. An amazing feat considering all the obstacles the project team had. Tight communication and a solid team effort made this a reality. Hats off to W.E. O’Neil!

Joseph Martinez Project Manager, Harrah’s Entertainment

I have found the responsiveness and willingness to help, of the W.E. O'Neil Team to be outstanding……I can honestly say that all my dealings with W.E. O'Neil have been nothing but professional, direct, honest, and that every expectation set has been delivered upon as promised.

Rob Kabza VP Construction Operations Pulte Homes

W.E. O’Neil was always there to protect the Owner’s interest with every aspect of the project. They were proactive and not defensive when any problems arose; a real Owner’s Advocate! We’d certainly like to use their professional construction services again.

Larry Nelson, Owner St Charles Town Company

From the multiple bidding stages, through creation of the design/build package, to the close-out of construction, W.E. O’Neil Construction Company demonstrated the highest level of quality and responsiveness on this demanding, high profile project. W.E. O’Neil used its considerable design/build expertise to schedule and complete this multi-phase d/b project three months earlier than the contract required.

John E. Smock, Resident Engineer, Army Corps of Engineers – Edwards Air Force Base

A collaborative effort was ever present while working with the design and construction teams on this Nordstrom project. From the Owner, Architect, Consultants and support staff, to the General Contractor’s field and office team, their subcontractors, extending to Nordstrom’s support staff and vendors, the effort and team camaraderie to make this a successful and fun project was outstanding!

Paul Hjorten, Associate Principal, Callison Architecture, Inc., La Cantera Team

We were delighted when we saw that O'Neil was the low bidder on one of our new projects, and we look forward to a long relationship with O'Neil both in California and other areas of the country.

Paul Chapman, Vice President, 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 family owned and controlled 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.

This project is the perfect example of how the owner, architect, and the general contractor should work as a team in order to achieve the finest end result for all parties involved.

Craig Dinkins, Associate Principal, Callison Architecture, Inc., North Park Team

The employees of O'Neil, from top to bottom, were without exception, professional, experienced, dedicated and talented. Perhaps most importantly, they brought the project in on time and on budget. To an owner, there are no sweeter words.
