W.E. O’Neil and Jim Baum: Decades of Partnership

Building premiere gaming and hospitality developments across California, Illinois, Louisiana, and Arizona markets.

Our collaboration with Jim Baum started in 2001 on our first gaming facility project with the Rincon Band of Luiseno Indians, during his tenure as Corporate Director of Development at Harrah’s Entertainment Inc.

Over the past 25+ years, our relationship with Jim has only grown stronger, even as he transitioned through different employers. Recently, in this video, Jim joined us to reflect on our enduring partnership and the lasting impact we’ve made together in developing premier gaming facilities, a true testament to mutual trust, shared vision, and long-term collaboration.

Testimonials

We’re slaying dragons when we build projects, and we have fun doing it. That’s what my relationship with W.E. O’Neil represents. I’ve worked with W.E. O’Neil for over 25 years across four gaming companies in five states, totaling more than $800 million in construction. From a temporary casino in California that grew into a major multi-phase development to bringing a riverboat casino landside in Louisiana, our like-minded approach and shared focus on relationships have been the foundation of this long-standing partnership.

The Rincon Tower Expansion was an overwhelming success in 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!

I commend the team that was on the Harrah’s Casino Expansion for their excellent job of managing the project from bid to completion. The communication and level of management input that was provided to our company was far beyond our expectations. Your superintendent’s management was instrumental in the successful completion of the project. I feel his example even had a positive impact on the attitude and productivity of our own staff!
