How do I litigate disputes on behalf of my clients?

I approach litigation by listening first, understanding what actually matters to the client, and then building a strategy that fits both the legal and human realities of the dispute. Complex business cases rarely follow a predictable script, which is one of the things that draws me to this work. From the outset of a case, I focus on seeing the bigger picture, identifying the issues likely to drive the outcome, and communicating candidly with clients about both risks and opportunities along the way.

Handling complex business disputes across multiple forums

Deric McClellan represents businesses and individuals in a broad range of complex commercial disputes in federal, state, tribal and bankruptcy courts. While his practice spans multiple areas of litigation, Deric concentrates primarily on sophisticated business litigation involving high-stakes factual and legal issues that demand innovative thinking and careful case development. His experience includes matters involving eminent domain, products liability, breach of contract claims, constitutional torts, non-compete agreements, landlord-tenant disputes, riparian rights and bankruptcy adversary proceedings, among many others.

Developing case strategy with trial and appellate perspectives in mind

Deric approaches litigation with an eye toward how a case will ultimately play before both judges and juries. From the earliest stages of a matter, he works to identify the core factual narrative, assess witness credibility, and anticipate the legal and procedural issues most likely to shape the outcome of the case. Drawing on his appellate background, Deric takes a broad, long-range view of litigation strategy, helping clients understand not only where a case currently stands, but also where it’s likely heading months or years down the road. He believes that effective advocacy requires seeing the full landscape early, whether that means positioning a case for summary judgment, preparing for trial or preserving issues for appeal.

Building persuasive narratives through communication and preparation

Deric recognizes that litigation decisions often involve considerations extending beyond purely economic analysis, and he works to build relationships that allow for productive conversations throughout the life of a case. Clients value his strong writing skills and his his direct conversational style, particularly his willingness to explain litigation risks, costs and potential outcomes upfront rather than offering unrealistic expectations. His prior experience working in sales before entering the legal profession also shaped his practical understanding of relationship-building and client service.

Bringing insight from federal judicial clerkships

Before joining Crowe Dunlevy, Deric served as a law clerk to the Honorable Stephanie K. Seymour and the Honorable John E. Dowdell. This valuable experience enhances Deric’s ability to approach motion practice and courtroom advocacy with a strong sense of what courts find persuasive, credible and effective—as well as what arguments are more likely to undermine a party’s position.

Delivering practical and efficient representation

Deric emphasizes efficiency, preparation and strategic focus throughout the litigation process. Because he views every complex business case as unique, he invests time in understanding the factual nuances, documentary history, and interpersonal dynamics underlying each matter. While he primarily represents defendants and corporate clients, his experience handling select plaintiff matters also provides additional perspective into how opposing parties and counsel may approach litigation strategy and case valuation.
