About CT Laboratories LLC
Experience cannot be overlooked. CT Laboratories LLC has been in business since 1987.  We are located in the heart of the Baraboo Bluffs in Baraboo, WI.  The lab was started back in the eighties as an off-shoot of the engineering firm Mid-States Associates.  Today, we are locally owned and continue to grow.  We are always increasing our capabilities and the locations we serve.

CT Laboratories' staff is comprised of dedicated, long-term employees. Key personnel, including our Laboratory Director, Quality Assurance Officer, Project Managers, Group Leaders and Senior Analysts have an average tenure of over 12 years with the company. We also understand that communication is the key to a successful project. Our clients are assigned a specific project manager to take care of their needs from initial project scoping and assistance with QAPP generation, to fulfilling bottle requests and verifying sample receipt through addressing technical issues and final report generation. 

Quality is not a given or an afterthought at CT Laboratories. Our quality assurance program is designed to ensure legally defensible data. From numerous performance evaluation studies, NELAP and other individual State audits, as well as our in-house program, we continually monitor our quality to ensure our clients get the best results possible.
