Mary M. Long


Mary M. Long began her association with the law and legal issues long before she became a lawyer. She served as a criminalist with the Oklahoma State Bureau of Investigation for twenty-one years as a forensic biologist. She began in the forensic serology unit and was part of the team that instituted forensic DNA testing in the State of Oklahoma. At the time of her retirement from the OSBI in 2001, she was the supervisor and technical manager of the OSBI’s forensic biology and DNA units. Mary has also served as an adjunct professor at the University of Central Oklahoma in the Master’s of Forensic Science program.

After retiring from the OSBI, Mary attended law school at Oklahoma City University and graduated with honors. She is licensed to practice law in both Oklahoma and Texas. She has also been admitted to practice in federal court in the Western District of Oklahoma and in the Tribal Court of the Cheyenne and Arapaho Tribes of Oklahoma. Her legal experience lies mostly in family law, criminal law and small claims and collections.

In addition to practicing law, Mary serves as a forensic consultant and can assist attorneys and others in understanding forensic science applications, obtaining materials for discovery, reviewing casework and investigations, examining evidence, and preparing attorneys to examine or cross examine forensic experts.
