  • Jack G Dekovich

    Clay is a skillful litigator that is fully committed not only to his clients but also to the rule of law. Mr. McCaslin's ability to tame the jungle of civil litigation allows him to ensure that his clients get the compensation they deserve. Clay is one of the greatest attorneys that I have ever had the pleasure of knowing. I endorse this lawyer.
