Zachary Reibstein, criminal defense attorney at Barringer Law Firm.

Zachary Reibstein, Attorney

A second-generation criminal defense attorney, Zachary Reibstein grew up in and around New York City. After working as a legal assistant post-college he accepted a full scholarship to pursue his J.D. in San Diego, California. Upon graduating in the top 10% of his law school class he returned to New York City and became a prosecutor with the Queens County District Attorney’s Office.

As a prosecutor in America’s largest city, Zachary handled thousands of cases ranging from minor misdemeanors to violent felonies. In addition to extensive trial-work he worked closely with NYPD detectives investigating major cases: responding to crime scenes, drafting search warrants, supervising line-ups and obtaining suspect confessions. His caseload included countless assaults, robberies and burglaries; as well as drug, economic and sex crimes. In one prominent case he successfully prosecuted the theft of religious objects worth half a million dollars.

Zachary initially entered private practice in 2009 after spending three years as a prosecutor. Specializing in criminal defense and civil litigation, he achieved numerous dismissals and not guilty verdicts for clients facing criminal charges, acted as special counsel to NYPD officers accused of misconduct, and recovered millions of dollars for clients injured due to negligence. In one representative case a jury found his client not guilty of possessing an unregistered handgun despite it being found in a car owned solely by the client while the client was alone inside it.

After six years in private practice Zachary joined the Special Operations, Narcotics & Gangs bureau of the Nassau County District Attorney’s Office. As a member of an elite bureau tasked with curbing an opioid epidemic, he successfully prosecuted violent crimes and narcotics conspiracies including “Operation Bundle-Up”: a multi-jurisdictional investigation that resulted in over 40 arrests and convictions – the largest drug network takedown in Long Island history.

Seeking a higher quality of life for his family, Zachary relocated to Colorado in early 2018; quickly gaining experience as a prosecutor in Denver and Broomfield counties, as well as with defense firms handling criminal cases through the state. Zachary takes his job as a defense attorney seriously and is laser-focused on holding prosecutors to their burdens of proof. If mistakes were made by law enforcement, he will find them and use them to his client’s advantage. Having grown up around the field of criminal justice, Zachary can investigate and assess a case better than anyone. As a former actor with extensive public speaking experience, his closing arguments at trial are particularly effective.

If you or a loved one have been charged with an offense, be it a minor violation or a complicated felony, Zachary will advise you thoroughly, fight for your rights aggressively, and provide you with the best representation possible.
