Established in early 2014, WilmerHale’s Denver office marks the firm’s entry into the Rocky Mountain region. The Denver office expands the firm’s footprint in the western United States and deepens our service to clients in several areas of signature strength, including energy and environment, investigations and litigation, strategic response, and Native American law. The Denver area is a major technology, energy research and financial center, a regional headquarters for government agencies, and an environment rich in natural resources. The Rocky Mountain region is the geographic heart of the country, poised for significant growth, and integral to the growing national and global economies.

WilmerHale’s energy and environmental practice is nationally known for advising companies in the technology, life sciences, energy and manufacturing sectors, and for shaping regulatory and policy developments on both a federal and state level. The firm’s strategic response practice handles multifaceted, high-profile challenges with legal, public policy and media dimensions. Our investigations and litigation practices draw on the collective experience of our many lawyers who have served in senior government positions, handling matters across the nation and abroad. The firm’s Native American law practice has a long track record of handling high-stakes litigation and complex regulatory matters on a range of issues—including energy and natural resource development, land acquisition, water rights, and gaming matters of particular importance in the western United States.

The Denver office was founded by WilmerHale Partners Ken Salazar and Tom Strickland.

Mr. Salazar served as US Secretary of the Interior, US Senator for Colorado, and Colorado Attorney General. Mr. Salazar is a Colorado native who draws on his high-level government experience and his singular insight into energy, environmental and natural resources matters, and tribal issues to assist the firm’s clients.

As Secretary of the Interior, Secretary Salazar helped lead the United States’ energy efforts in developing conventional and renewable energy resources on the nation’s public lands and oceans. As a US Senator, he served on the Energy and Natural Resources and Finance Committees, which oversaw the nation’s energy, natural resources, tax, trade, social security and healthcare systems. As Colorado Attorney General, Mr. Salazar oversaw thousands of civil and criminal legal matters and investigations. Before his election to public office, Secretary Salazar worked in private practice for 11 years as a natural resources and environmental lawyer.

Before joining WilmerHale as a partner, Tom Strickland worked for more than 30 years in both the private and public sectors. Mr. Strickland served as Colorado’s US Attorney, worked as lead policy advisor to the Governor of Colorado, and served on numerous state commissions, including the Great Outdoors Colorado Board and the Transportation Commission. Mr. Strickland also served as Assistant Secretary for Fish and Wildlife and Parks and as Chief of Staff to the Department of the Interior. As Assistant Secretary, he supervised the nation’s conservation agenda, including national parks and wildlife refuges.

In the private sector, Mr. Strickland has worked as an environmental and regulatory law partner in leading national law firms in Denver for more than 20 years. Mr. Strickland has also served as General Counsel to the largest health insurance company in the United States.
