W. K. Thomas & Associates is a private, family-owned construction company with offices in Butler, PA, and serving all of western Pennsylvania. Second generation family member, Brent Thomas, has been leading the company since 1999 and continues to grow its success.


W. K. Thomas displayed excellent project control, regularly offered value engineering suggestions, interfaced very effectively with the independent architect and other team members and was a delight to work with. As a result the extremely demanding project, where they were required to integrate several European design standards not common in the US, was completed with a minimum of issues and under budget. I would recommend W. K. Thomas to any company looking to complete any form of building project. They are a very professional team who cares about the Customer and the quality of the product.

My experience with W. K. Thomas & Associates was exceptional. From the first time I met with Brent Thomas through the whole process the project was seamless. We had zero problems, zero setbacks and it was absolutely trouble free. My advice to anyone wanting to build a building is to sit down with W. K. Thomas & Associates, tell them what your needs are and let their design team go to work for you. After we signed off on the final plans it was only a matter of months before we were able to move in and there were never any problems or delays. It was truly an exceptional experience.

I would highly recommend them to anyone thinking about a new building for their business.

We recently had the pleasure of working with Brent Thomas and W. K. Thomas and Associates during the remodel of our downtown Butler business. They were able to turn our three floor, ninety year old building into a modern, comfortable, and safe space. The addition of an elevator allows our office to be fully handicap accessible. The work was of the highest quality, and we were able to remain open with no interruption of care to our patients.
