Mary E. Conn

Federal & State Criminal Defense Lawyer in Harris County TX, Houston TX & Beyond

If you or someone you care about is in trouble with the law, Mary E. Conn Law, can help. The firm was founded in 1985 out of Ms. Conn’s desire and talent for helping people. Ms. Conn is licensed by the Supreme Court in Texas and the State Bar of California, several Federal Courts, including the Supreme Court of the United States, and practices in both states as well as all Federal Jurisdictions.

The firm delivers trial and pretrial services, in state and federal criminal cases, civil trial cases, adult and juvenile, criminal or delinquency cases, felony and misdemeanor cases, and select civil matters, including forfeiture cases. Typical cases range from capital murder, murder, and other crimes of violence to white collar crimes, DWI/DUI, conspiracies, sex cases, drugs, controlled substances, and all other criminal charges.

Ms. Conn is able to assist those who have been found guilty while represented by others, as she is skilled at sentencing advocacy under the Federal Sentencing Guidelines, the new laws in federal courts, and in the State Courts of Texas.

The firm also handles some carefully selected civil matters. The firm has conducted numerous jury trials and many non-jury hearings and trials. Many of Ms. Conn’s clients’ cases have been dismissed prior to trial, and prior to formal charges being brought.
