Overview

Meet Claire M. Elster, Defense Attorney and Advocate

Claire Elster didn’t always plan on being a criminal defense attorney. In fact, she first dreamed of working in family law — until she saw how often the system was used as a weapon between people who once loved each other. Looking for a way to make a real difference, she found her path in criminal defense. What she discovered was a profession that let her fight for people when they’re at their most vulnerable — and offer them a way through.

Since opening Elster Law Office in 2018, Claire has built her practice around one simple principle: every person deserves to be treated like a person, no matter what they’re accused of.

Background and Credentials

Claire began her legal career in Colorado in 2009 after earning both her journalism degree and law degree from the University of Missouri; where she graduated with top honors. While in school, she rose to the top of the national arbitration circuit — taking second place at nationals and developing skills that would shape her courtroom style.

Early in her career, Claire worked on some of the most difficult criminal defense cases imaginable — including sexual assault defense and even a wrongful death case involving police brutality. That experience shaped her deeply, and today, she brings both strength and sensitivity to every client she represents.

Ms. Elster was recently recognized as one of the Top 10 in Criminal Defense in Colorado by NACDA (National Academy of Criminal Defense Attorneys). Judges, District Attorneys and defense colleagues alike, all know and respect Ms. Elster for her straight-forward, professional and dedicated conduct both inside and outside the courtroom. Ms. Elster always puts her clients’ goals first, working tirelessly to achieve a just and favorable outcome for each and every person she represents.

She’s also a proud coach of her local high school mock trial team — a way she gives back to the legal community and supports the next generation of advocates.

Ms. Elster graduated with top honors from the University of Missouri School of Law and since then has been nationally recognized for her work as a criminal defense attorney. Ms. Elster was previously awarded a Top 10 Under 40 in Criminal Defense by NACDA (National Academy of Criminal Defense Attorneys) and is currently listed as one of the Top 10 Criminal Defense Attorneys in Colorado by NACDA. Judges, District Attorneys and defense colleagues alike, all know and respect Ms. Elster for her straight-forward, professional and dedicated conduct both inside and outside the courtroom.
