About me

Mark Metzger was born and raised in Houston, Texas. Mark attended Elkins High School before graduating from the Marine Military Academy in 1999. While at Elkins High School, Mark played trumpet in the marching band and was an officer in the JROTC program. At the Marine Military Academy, Mark served as the Platoon Sergeant of Charlie Company and played on the football team. During his high school years, Mark was also cadet officer and later second lieutenant senior member in the Civil Air Patrol and a member of the Boy Scouts.

Mark then enlisted in the United States Marine Corps and attended boot camp at Marine Corps Recruit Depot San Diego in 2000. Upon graduation, Mark attended the Department of Navy’s Cryptologic Training School at Corry Station in Pensacola, Florida. After graduating as the Honor Graduate and earning a meritorious promotion, Mark’s military occupational specialty became an Electronic Intelligence Analyst (MOS 2631). During his tour in the Marine Corps, Mark worked directly under the National Security Agency and Central Security Service with participation in Operations: Northern/Southern Watch; Enduring Freedom; and Iraqi Freedom. When off duty and in his spare time, Mark volunteered as a Drill Instructor for the local Young Marines program. Mark received his Honorable Discharge in 2007 at the rank of Sergeant.  Subsequently, Mark worked for Lockheed Martin/Martin Marietta as a site security supervisor and other various security contractors.

Upon returning to his native Texas as a ranch hand on an exotic game ranch, Mark then attended and graduated from Texas A&M University in 2009 with a Bachelor of Arts in Philosophy. While at Texas A&M, Mark played linebacker/defensive end for the Aggie football team (#59), studied abroad in Bonn, Germany, and tutored students in Logic and Liberal Arts classes for the Texas A&M Student Athletic Department.  He then came back home to Houston and continued his education at South Texas College of Law (STCL).  While attending STCL, Mark participated in summer trial academy and various law societies to include serving as an elected officer in the Delta Theta Phi international law fraternity.

Mark is also a recent graduate of Gerry Spence's Trial Lawyers College.  Located at Thunderhead Ranch in Dubois, Wyoming, it is considered the most prestigious and selective trial advocacy college in America. To date, Gerry Spence has only graduated just over 1,200 students over the past 20 years.

Mark is a member of the Texas Criminal Defense Lawyers Association, Harris County Criminal Lawyers Association, The National College of DUI Defense, DUI Defense Lawyers Association, Houston Bar Association, and Delta Theta Phi international law fraternity alumni association.

Outside the courtroom, Mark is a founding owner of Sixell Innovations, a registered Department of Defense Manufacturer, which specializes in tactical weapon accessory manufacturing.  Locally, he owns and operates a welding and custom fabrication shop in Spring Branch, which specializes in custom motorcycle builds, restoration, and modifications.  Mark is also an ordained minister, while working on completing his Ph.D in Theology and Apologetics.

  • Sean Reza Darvishi

    I endorse this lawyer. Mark is an outstanding lawyer who zealously advocates for his clients. I knew Mark when I was an intern at the District Attorney's Office and now as a fellow criminal defense attorney and I always respected the great work he does. I would highly recommend.

  • David Christopher Hesse

    I call Mark a friend and an excellent Criminal Defense Attorney. We are friends because we both served in the Marine Corps. I can see his fire and determination in defending his clients. The same amount of effort he put into serving in the Corps is carried over to Defending his clients. Mark recently assisted me on a DWI case and helped pick a Jury. He knows how to read people. There are many lawyers who give lip service to their clients and do little to nothing. And there are few who actually care and fight. Mark is one of those few.
