“My firm used Ken Roush as an expert witness in a large highway interchange construction mediation. Mr. Roush was very thorough in his approach and extremely knowledgeable of the concrete industry, specifications and technicalities of this construction. He was a great facilitator to the successful conclusion of this matter.”
– Plaintiff Attorney

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.”
