Thomas Engineers offer a full complement of structural engineering services. Projects are managed with the goals of the client always in mind. Our work is necessarily grounded in principles of mathematics, materials science and engineering, and the art of applying these tools in practice. We use the highest level of technology appropriate to the project. Results are given in straight-forward language appreciated by our clients. Our focus is the integrity of the interactive relationship with our client, and the quality and economy of the project. Each client and every project has the direct professional and personal attention of the principal engineer.

A large portfolio of successful designs for buildings, bridges, and special structures is augmented by work in structural dynamics, structural stability, and computation science. Clients include industrial and commercial enterprises, public institutions, and government.
