About Me

Throughout his life and career, security consultant, law enforcement professional, and former Marine Staff Sergeant Chris Grollnek has maintained involvement in a vast array of educational, professional, civic, and personal endeavors. As a member of the United States Marine Corps from 1992 through 2003, Grollnek ascended through the ranks of Private First Class, Corporal, and Sergeant before reaching Staff Sergeant, serving in such capacities as Senior Drill Instructor, Close Combat Instructor, Master Instructor, and Assistant to the Commanding Officer of the Marine Corps Detachment. Following his honorable discharge, while awaiting his classification by the U.S. Department of Veterans Affairs as a disabled veteran in 2000 Chris Grollnek joined the 4th Reconnaissance Battalion, H&S Company, in San Antonio, where for the next three years he performed as Armory Staff Noncommissioned Officer in Charge and Reserve Battalion Operations Chief. In addition, Chris Grollnek completed an internship as a Personal Protection Officer at Perot Systems (since acquired by Dell) in Dallas and earned his B.S. in Business Management and Leadership Studies from the University of Maryland University College during this time.By 2003, Chris Grollnek had joined the McKinney Police Department in McKinney, Texas, where he continued to diversify his skill set as a security expert.
