About me

Mark Kendall Bailey was born in Alexandria, Louisiana. After graduation with distinction from Louisiana College with a B.S. in Criminal Justice, Mark worked as a licensed Firearm Instructor and tactical Baton Trainer for law enforcement personnel. In 2001, Mark received his Juris Doctor from Oklahoma City University School of Law.

Mark successfully defended major corporate clients, such as Wal-Mart and Home Depot, in numerous trials across Oklahoma.

However, in 2003, he shifted his legal focus to criminal defense litigation and began working for the Oklahoma County Public Defender’s Office, where Mark was responsible for managing, negotiating, and litigating thousands of felony cases, ranging from DUI to Murder in the First Degree. Based on his extremely high success rate, Mark was promoted to Supervising Attorney, where he was responsible for training others in the professional and appropriate representation of clients. After leaving the Public Defender’s Office, mark continued with criminal defense representation for the Oklahoma firm Atkins and Markoff. In 2010, Mark incorporated his own firm for the continuation of legal work within the private sector.

Mark practices law in state courtrooms across Oklahoma and Texas, as well as in the Unites States Federal District Courts for the Western and Northern Districts of Oklahoma. Mark appreciated the value of reputable legal education, and has taught college classes on Jury Selection techniques and Forensic Firearms Evidence. He also teaches Continuing Legal Education courses with the Oklahoma Bar Association, and is one of the legal educators for Self-Defense Act licenses for H & H Shooting sports. He is also an active member in the Armed Citizens Legal Defense Network, Armed Citizens Alliance and listed in the National Rifle Association Business Alliance.


Mark is currently affiliated with numerous legal associations that further the respect of the legal profession, such as the National and Oklahoma Criminal Defense Lawyers Associations, Oklahoma Bar Association, and the Texas Bar Association.
