Attorney Profile

Joseph Anthony Lazzara Attorney Joseph Lazzara

Denver Criminal Defense Attorney

My name is Joseph A. Lazzara, and for the last 20+ years I have focused my legal career on helping people who face criminal accusations in the state of Colorado. I strongly believe that everyone is entitled to excellent, high-quality representation, and that’s how I organize my practice here at the Law Office of Joseph A. Lazzara, P.C. I am an experienced and aggressive trial lawyer with a long track record of success. I am also proud to serve clients who have been injured and who have potential personal injury claims. Whether serving my clients in criminal or civil court, I am more than prepared to fight for their rights and interests. I am admitted to practice law in all Colorado courts.

History of Excellence & Experience

I attribute my courtroom success at least in part to my work as a clerk to Chief Justice Opala of the Oklahoma Supreme Court, which gave me an insider’s view and an invaluable perspective of the justice system. Observing the inner workings of a State Supreme Court Judge so closely gave me an edge and the ability to effectively and intelligently represent my clients. I received my undergraduate degree from Adams State University in Colorado and my J.D. from the University of Oklahoma College of Law in Norman, Oklahoma.

My goal is to give back to my community. That’s why I served as an adjunct professor at Metropolitan State College in Denver. I am a member of multiple professional legal groups including Colorado Bar Association, Colorado Criminal Defense Bar Association, National College for DUI Defense, National Association of Criminal Defense Lawyers, The National Trial Lawyers Top 100 Trial Lawyers, Arapahoe County / Douglas County Bar Association. I have an A+ rating with the BBB, part of Haystack Help Radio, the sole attorney for Tom Martino's Legal Help Center and a proud member of Tom Martino’s—the “Troubleshooter”—referral list. Also, I have been included in the Who’s Who Among American Attorneys.

My bar admissions include:

  • Colorado, 1993
  • United States Court of Appeals 10th Circuit, 1993
  • United States Court District of Colorado, 1993
