Honest dependable Attorney
From start to finish Attorney Callas had my best interest at heart. He explained everything in detail, and In layman’s terms, because legal verbiage is confusing to me. I wouldn’t hesitate to hire him again. Plus his paralegal is great too!! Thanks again for all your hard work!!
