Daniel D. Williams

Dan brings a passion for creative and aggressive advocacy to the practice of law, making him a highly successful trial lawyer.  He handles bet-the-company and other complex commercial litigation matters for clients in a broad range of industries.  In the last several years, this has included defending multi-million-dollar class actions; litigating complex real estate disputes; handling fraud and RICO cases; litigating employment and non-competition disputes; and handling business disputes for emerging and established companies of all shapes and sizes.  The unifying theme through his practice is a keen awareness of his clients’ needs as cases progress from pre-suit negotiation through trial.  This requires listening as much as talking, and proactively designing legal strategies that meet the unique goals of each client. 

Before becoming an attorney, Dan served as an advisor at the U.S. Department of Health and Human Services, working on welfare policy and community development programs.  At the beginning of his legal career, Dan practiced at the leading litigation firm in Washington, DC, Williams & Connolly LLP.  He then relocated to Colorado in 2007, and began practicing at an international law firm with offices in Boulder and Denver. In 2016, he co-founded Williams & Daley LLC.
