Mary kept me out of prison.
I was facing prison time and Mary was able to get me deferred adjudication. She was very extremely patient with me, carefully explaining the law regarding my case. She was always professional and I was not the most desirable client.
If I am ever in need of a award winning acclaimed lawyer again, there is no doubt that it will be Mary Conn.
Bob, Criminal Defense Client
She always believed me when I said I was innocent.
I was arrested at school during my senior year of high school September 2010 and charged with Capital Murder (multi). Mary Conn took on my case in the Summer of 2014. She always believed me when I said I was innocent and promised to fight for me til the end.
Mary Conn did just that. I walked out of the Harris County jail on July 2, 2015 after a jury of my peers could not find me guilty.

Best attorney around!!! A++++ FI-1 FIRST PAROLE!!!
I hired Ms. Conn to represent my husband on his first parole review. My husband had a 35 year sentence for a serious crime, and was a parole violator.
Ms. Conn walked me through the process of parole from the beginning until the end. Ms. Conn and I personally appeared before the Board Member voting on my husbands release. My husband was home in my arms 32 days later!!! Can I say more???? This is the attorney you need to hire!!!!”

Thanks for the gracious advice.
I want to say thank you for your gracious advice. Your sincere, calming advice reminded me of when I use to work at a hospital, helping people that couldn't help themselves. It also reminded me of how I managed to be a primary caregiver for my wife having cancer, who eventually passed away some years ago.
Thanks again for your kindness & reminding me to continue helping people.

Criminal Defense Information
The smallest criminal offenses can have a lasting impact on your future if you do not take the time to properly handle the penalties. It is a common misperception that misdemeanor offenses will be “wiped off” your record easily as the years go by. However, a misdemeanor has the potential to develop into a felony if you do not receive the appropriate advice of legal counsel.
Criminal law developed from the initial Code of Hammurabi thousands of years ago. Since this time, modern civilization evolved to develop the common law court system, which provided the backbone of most criminal courts in the United States, including Texas. Criminal laws have expanded over time to now include both large and small penalties, as well as corresponding punishments and penalties.
Texas Criminal Laws
In Texas, criminal offenses are divided between felonies and misdemeanors. Felonies have penalties that range from 180 days in state jail (for a state jail felony) up to the death penalty (for a capital felony). These ranges are in addition to a fine up to $10,000 per offense. Misdemeanor offenses have a punishment range of up to one year in county jail. Many misdemeanors do not involve any jail time, but instead require the defendant to pay a fine of up to $4,000.
If you are facing criminal charges, you need a award winning acclaimed lawyer who can defend you and protect your legal rights.
Criminal law has attracted the imagination of authors, playwrights, and producers alike over the years. However, criminal law is not as glamorous as the movies and news media make it out to be, and many criminal law offenses can have dire repercussions for everyone involved. It is therefore important to consult with an experienced criminal defense attorney as soon as you are arrested for a violation.
The Texas Penal Code contains an extensive list of all felony and misdemeanor offenses. It is important to keep in mind that a combination of misdemeanors may lead to a felony. Failure to speak with an attorney during the sentencing of a misdemeanor may eventually lead to a felony conviction several years down the road. While you may receive a lighter sentencing (depending on the facts and circumstances of your case), a felony conviction will follow you throughout life and will impact your ability to maintain employment. It is therefore important to speak with a criminal defense attorney as soon as possible.
