Our task as litigators is to advocate for our clients by crafting persuasive arguments.  In order to do so effectively, we must understand our audience, use language effectively, and craft a compelling story. We tell our clients’ stories for the first time on the page; our legal briefs are often our first opportunity to present their cases and persuade the court. I am a lawyer because I love the process of crafting an argument—taking the time to consider both sides, researching the law on all issues, and finding a creative approach to articulating our best case.
