“Ken Roush did an outstanding job as an expert witness in litigation involving a major concrete bridge in the Florida panhandle. Ken identified that the contractor’s inability to obtain passing test results was due to a defective concrete specification. As the result of Ken’s involvement, we were able to negotiate a significant settlement in favor of the contractor.”
