WilmerHale's Denver office has expanded the firm's presence in the Rocky Mountain region. Over the past decade, innovators, entrepreneurs and business leaders have converged on Colorado, which routinely ranks among the top states in the areas of best places to live, fastest growing economies, best business climates and most educated workforces.

Our Denver-based team includes lawyers with significant legal and government experience—Partners Ken Salazar, Tom Strickland, Andy Spielman and John Walsh—and is recognized for having extensive knowledge in the areas of energy and environment, intellectual property, investigations and litigation, corporate, strategic response, and Native American law. Our IP lawyers—including Natalie Hanlon Leh, Ben Fernandez and Mindy Sooter—represent clients on a range of issues involving patent, copyright, and trademark and trade secret law, and serve as lead counsel in high-profile patent litigation and prosecution cases. Expanding the firm's Corporate Practice in Denver, Keith Trammell counsels public companies, private equity funds and privately held companies on capital markets and merger and acquisition transactions.

All of our lawyers represent numerous Colorado and Rocky Mountain companies, and also support clients headquartered in other cities and countries. The firm's Intellectual Property Department and IP Litigation Practice, which include lawyers from the Denver office, are consistently ranked among the best in the United States by Chambers and Partners, Law360 and The American Lawyer. The lawyers in our Energy, Environment and Natural Resources Practice, led by Andy Spielman, help clients achieve their business objectives in a range of regulatory, litigation, legislative and transactional matters at the intersection of law, business, science and public policy.

WilmerHale's preeminent Native American Law Practice has a strong record of handling high-stakes litigation and complex regulatory matters, with lawyers representing tribes on a variety of issues such as energy and natural resource development, land acquisition, water rights, gaming matters, and tribal sovereignty. Our Strategic Response Group assists clients in navigating multifaceted challenges with legal, public policy and media dimensions.

Drawing on the collective experience of the firm's 1,000 lawyers located throughout the United States and around the world, we are able to serve leaders of the Rocky Mountain region's business community and are dedicated to growing the economy and making Colorado a sought-after place to do business. We are also deeply invested in our community, and regularly provide lawyers and staff with opportunities to make an impact through pro bono and community service. We recruit talented and accomplished lawyers and staff in Denver and are proud of our diverse and growing office, which is 57% female and 34% minority, and is co-led by Natalie Hanlon Leh.
