Mary is an attorney with the Dallas office. Her primary focus is First-Party Property Claims and coverage-related litigation. As a double engineer, with a Bachelor in Electrical Engineering and a Masters in Mechanical Engineering from the University of Nevada Las Vegas (“UNLV”), Mary understands technical issues with a distinct acuity and different angle while working with experts in various fields.

Before becoming an attorney, Mary gained real-world engineering work experience. As a systems engineer, she worked at Sandia National Laboratories located inside Kirtland Air Force Base, Albuquerque, NM. She also worked on several public works projects in Nevada and Arizona, including projects at the Clark County Water Reclamation Department, UNLV, and the City of Las Vegas. She also worked as a construction manager on private projects, including the Fashion Show Mall food court located on the famous Las Vegas Boulevard. While an engineering student at UNLV, Mary and her team won third place in a national competition involving electromagnetic innovation research and testing project at Nellis Air Force Base, Las Vegas, NV.    

Prior to joining Butler, Mary was a first-party property insurance attorney representing insureds.  She also served the State of Texas as an Assistant District Attorney, handling Juvenile cases, Child Protective Services (CPS) cases, and Misdemeanor cases. Before that, Mary served the City of Houston to assist Indigenous Texans with Hurricane Harvey claims for contractor fraud, FEMA benefits denials, and bank foreclosures on flooded homes.  

Mary’s Egyptian and Greek ethnic background, in conjunction with her middle and high school education in a French Catholic school with a certificate from the Alliance Française, allows her to be culturally sensitive on potentially complex international matters.  Mary is fluent in both Arabic (Egyptian dialect) and French.

Mary is fond of Texas and the Texan community, particularly because of the programs the State initiates for the assistance to those in need, such as those displaced due to floods, programs created to assist juveniles, and programs created to assist and support the disabled. 

Mary is admitted to the Texas Bar, the U.S. District Courts of Texas, and the U.S. Court of Appeals for the Fifth Circuit. She is a member of the Christian Legal Society in Houston and in Dallas.
