Dean Neuwirth
 

Dean Neuwirth brings more than 30 years of legal experience to his appellate practice, and 20 years handling appeals. He has won a dozen published opinions, including before the Tenth Circuit and the Colorado Supreme Court. Dean has also prevailed in many appeals in the Colorado Court of Appeals. 

In handling appeals, Dean focuses on his client’s goals, the trial record, and existing law to determine not only how best to win the appeal, but also how to use the appellate process to try to preserve good law for his clients or change unfavorable law. 

For eight years, Dean collaborated with former Colorado Supreme Court Justice Jean Dubofsky on appeals, including several high-stakes and high-visibility matters. During their time together, the two handled nearly 30 appeals. 

For many years, The Best Lawyers in America and Colorado Super Lawyers have both recognized Dean for his appellate work.
