About me

For over 23 years, attorney, Craig N. Mastro, has been providing skilled and aggressive criminal defense to people throughout the State of Colorado. In addition to being an experienced trial attorney, Mr. Mastro uses his communication skills at pre-trial hearings or in conferences with local, state and federal prosecutors to negotiate the withdrawal of charges, reduction of charges or sentences, and alternatives to jail for his clients. Mr. Mastro is known as an experienced lawyer who knows how to seek the best possible solutions to each client's unique legal problems.

If you or a loved one has been accused of a crime, it is important to get all the information you can and proper representation. Feel free to call Craig at his office or on his 24 hour line. Mr. Mastro offers free initial consultations and can usually give you a few minutes to answer questions you may have, even if you are not interested in retaining his services.

    I have worked with and against Craig. If you hire Craig, you can rest easy knowing he's doing the heavy lifting. He's an excellent litigator and he has the respect of the DA's he works against.
