A national Law360, Texas Super Lawyer, and Texas Tech Rising Star,” Will is invested in his clients and the legal counsel he provides. In all aspects of his diverse practice, Will draws upon his understanding of contract, commercial, and environmental law, his ability to prioritize and assess risk, and his experience in resolving legal conflicts to help his clients address current challenges and position them to seize future opportunities.

A significant part of Will’s practice involves serving as outside general counsel for companies without their own legal departments or in-house counsel. Acting as a quarterback, Will plays an instrumental role in addressing all the legal needs of these clients, including general corporate matters, contract drafting, risk allocation, employment, and various regulatory issues, such as environmental permitting, responding to administrative enforcement actions, and workplace safety. His steady hand, clear guidance, and demonstrable commitment to his clients’ success have made Will an invaluable advisor and ally for businesses across a broad spectrum of industries.

An experienced and effective trial attorney, Will also represents clients on both sides of the docket and in various contexts.

He has handled lawsuits involving real estate transactions, commercial contracts, eminent domain, oil and gas matters, partnership disputes, wrongful discharge and employment discrimination, trade secrets, non-compete agreements, and other business-related torts.

Will has also counseled industry clients and public entities in high-profile environmental contamination cases. In those cases, Will has pursued and defended claims involving property damages, tort damages, remediation, allocation, cost recovery, and natural resource damages under state and federal statutes and the common law.

Organized, prepared, responsive, and trustworthy, Will brings common sense to any situation, allowing him to streamline communication and identify not only what is important to his clients but also to opposing counsel and their clients—a skill that often leads to efficient and favorable outcomes.

However, when settlement is not an option, Will is prepared and ready to go to trial to achieve his clients’ desired results.

My clients are often close friends—or become close friends—in large part because they know I’ve got their backs and genuinely care about their success.”
