About me

I have spent my entire legal career defending citizens accused of crimes.  I find my work deeply rewarding.  I think there is likely not a more noble calling than protecting the constitutional rights of those who have had their lives turned upside down based on mere accusations.

  • Christopher Daniel Leroi

    I endorse and would recommend Mr. Brengle to everyone and anyone. I have been practicing for 24 years. I was the youngest judge in Colorado history, a magistrate, a prosecutor in three districts, a law professor, and have worked in private practice for years. I still learn from his Avvo answers each and every day. He is a huge credit to the legal system. Hire him.
