Get on the Road To The Best Possible Outcome.


The Best Defense Is A Good Offense

Most criminal defense attorneys wait until hearing dates or until the prosecutor offers a plea bargain before taking action on your criminal defense case. This is reactive and ineffective. You cannot afford to settle for less than the absolute maximum effort to minimize the impact of an arrest on criminal charges.

At The Law Offices of Mark Deniz APLC, we take a proactive approach that doesn’t waste time waiting for an initial court date. Mr. Deniz, a former prosecutor, will immediately begin reviewing the facts of your criminal law case to identify any weaknesses that can be used against the prosecution.
