How did your firm decide on the primary area of practice(s)?

Baumgartner Law is dedicated to defending those accused of crimes, because we know exactly how unfair and unreasonable the criminal justice system can be. Everyone deserves a rigorous defense, not just the innocent, and that is exactly what we provide. No client will ever get less than our full effort and attention.

What experience or education distinguishes your lawyers from others?

At Baumgartner Law, we handle not just criminal defense cases, but also Federal Police Brutality and Police Misconduct cases. We know exactly how the police operate and how to question police officers. That gets our clients great results.

What distinguishes your law firm from others?

Baumgartner Law prides itself on it's client-centered practice philosophy. We know that a great defense doesn't have to sacrifice client service and responsiveness. When you have been charged with a crime, you need an attorney who both knows the law, and how to guide you through the process. We know this is a scary ordeal, and we are here to help you through it.

Birk Baumgartner

My name is Birk Baumgartner, and I am the principal at Baumgartner Law, LLC. I graduated Cum Laude from Southern Methodist University Dedman School of Law, and have been a litigator ever since. I am the fourth attorney in my family, but unlike my family members, I declined a job at a big law firm. Instead, I decided to dedicate my practice to a limited number of cases, with focused and individualized care. I believe that access to great legal counsel should not be limited to those that can provide large up-front retainers. I will always listen to anyone's legal questions and provide the best advice possible; and I will work to find a financial arrangement that works for you.

Daniel Mossinghoff

I am Daniel Mossinghoff and I am proud to be the Criminal Defense Director for Baumgartner Law, LLC. I have been a criminal defense trial attorney for almost all of the 20 years I have been practicing. I am dedicated to protecting the rights of anyone accused of a crime and vindicating those wrongfully charged.
I graduated Magna Cum Laude from Regis University in 1996 and then graduated law school from the University of Colorado in 2000. As a fledging lawyer, I cut my teeth and learned trial work as a district attorney for four years. Fairly quickly, I realized I was not meant to work as a prosecutor and quit. I missed working with people and arguing to protect our Constitutional rights.
Since then, I have been a criminal defense attorney for the last 16 years. I have defended thousands of clients in the areas of DUI defense, juvenile law, domestic violence and major felony cases. I have tried over 150 jury trials and countless motions hearings. My former partner and I successfully defended a client charged with Murder in the 1st Degree. I have also presented or been published over a half dozen times in multiple areas of criminal defense. Finally, I have been recognized as a Rising Star by Superlawyers and received recognition by other ranking organizations. I am currently ranked 10/10 on AVVO.
I am invigorated to work with the legal team at Baumgartner Law, LLC. This firm intentionally created a team of lawyers who will work synergistically to give you the best defense available. I hope you will entrust your criminal matter with us.
