Misdemeanor Defense

Knowing the consequences of a misdemeanor 

conviction and the best defenses to use in court is the job of an experienced criminal defense attorney. Some misdemeanor charges may even result in jail time, in addition to fines and other burdens, so it's important to have the right advocate on your side.



& Sealings

Sealing or expunging your criminal record can have great impact on your ability to obtain employment, housing, and other opportunities. Many people do not know that even arrests with no conviction create a criminal record. If you have questions about your criminal record, please call us and we can advise you on whether you should try to seal your record.


Violent Crimes

Assault cases come in many forms. Depending what the charge is may greatly impact the severity of your case. In the event you are charged with a violent crime, it is essential to retain a skilled and experienced criminal defense lawyer. Let us guide you in the right direction to help you get through this difficult time.

White collar crimes typically involve financial crimes, cyber crimes, identity theft, health care fraud, insurance fraud, fraud in commercial matters & other nonviolent offenses.  If you have been charged with a white collar crime or have been notified that you are under investigation due to an allegedly fraudulent claim and are concerned about potential liability, call us.


Property Crimes

Although these crimes are typically non-violent and do not carry overly harsh penalties, it is important to remember that any type of criminal conviction will cast a long shadow over your future. Do not just give up and accept a conviction! Instead, get help from experienced property crimes defense attorneys like Macedonio & Duncan.
