Mr. Mark Kostos


Mr. Mark Kostos is the originator of the newest program at Lewis & Clark, arriving prior to the 2021-2022 school year.  Mr. Kostos has extensive experience in the law enforcement field.  Originally from San Diego, California, he joined the United States Marine Corps out of high school, ultimately rising to the rank of Gunnery Sergeant.  During his nearly 14 years of active duty, he worked in military intelligence, specializing in the Korean peninsula.  

After a special duty assignment with the Federal Bureau of Investigation and the Naval Criminal Investigative Service, Mr. Kostos chose to leave the Marine Corps and enter law enforcement.  He first served as a Border Patrol Agent in the Rio Grande Valley in Texas; and later as a police officer in the city of Irving, Texas.  The events of 9/11 spurred him to join the Federal Air Marshal Service (FAMS) where he served for a number of years as an in-flight security officer.  Subsequently, he supervised the training section for the FAMS Chicago Field Office, and ran one of the Visible Intermodal Prevention and Response Teams.  His most recent assignment was as the Assistant Federal Security Director for Law Enforcement with the Department of Homeland Security/Transportation Security Administration at St. Louis - Lambert International Airport. 

Mr. Kostos is married and has two adult children, and two grandchildren.  When not at Lewis & Clark, Mr. Kostos enjoys spending time with his family, hunting, fishing, and golf.  He also cheers on the Chicago Cubs. (But please don’t hold that against him!)

President Theodore Roosevelt said, “To educate a person in the mind but not in morals is to educate a menace to society.”  My goal at Lewis & Clark is to provide my students with the ethical, physical, technical, and tactical skills needed to put them on the path to becoming the next generation of great law enforcement professionals.

  • 1 or 2 year program; 3 credits per year

    The Law Enforcement program is a one year program with an optional second year that focuses on the core principles of criminal justice, the basic knowledge, skills, and standards taught at Missouri Peace Officers Standards and Training Program (POST) Certified Police Academies, and the curriculum from Missouri’s Department of Elementary and Secondary Education (DESE).  Professionalism, character, and integrity are embedded into this program and serve as a foundation for every participant. In addition, the program includes a strong emphasis on communication (verbal, non-verbal, and written) and teamwork.  

    This course will include many opportunities for students to connect classroom experiences through practical application.  Students will be involved with investigation techniques, law enforcement procedures and protocols, and courtroom etiquette.  

    Students will be taught the materials and skills using a variety of teaching and learning methods.  They will have daily lessons or learning activities where students will be expected to actively participate.  Some examples include: class discussions, lectures and slide presentations, practical skill demonstrations, drills and exercise, physical training sessions, team building activities and “role play” scenarios.  Students will be required to complete various assessments, worksheets, written assignments, oral presentations, practical exams, group/team projects, and physical training tests.

    This program will be foundationally built on principles of character and leadership development.  As such, student professionalism, participation and behavior will be assessed and included in the student’s overall grade at between 25%-35% of the total grade.  Students will have an opportunity to earn class professionalism points each day for professionalism.  Examples of being professional include: being on time, wearing a clean neat uniform, listening and following instructions, actively participating in class, and using professional language. 

    Physical training is a part of the Law Enforcement curriculum.  Students should be able to: perform basic physical exercises and be generally physically fit; tolerate the loud sounds associated with law enforcement, such as sirens, bangs and yelling/vocalizations; climb, lift, bend and handle taxing physical activity; tolerate an environment including high places, small spaces, extreme temperatures, and dirty environments.  A physical examination by a medical professional (such as a family physician) will be required for students enrolling in the law enforcement program.  More specific information will be provided during the summer.  

    Uniform Policy

    Uniforms will be worn daily. The uniform will consist of a blue polo shirt with the Lewis & Clark Law Enforcement Program logo, khaki cargo pants, and black polishable boots.  A police duty belt with equipment will be provided. The shirt must be tucked into pants. Hair should be pulled back off the collar/shoulder. Exposed jewelry is prohibited except for small stud earrings on women.  On physical training (PT) days, uniforms will consist of black shorts or workout pants, grey t-shirt or sweatshirt with the LE Program lolg, and athletic shoes.

    Students will have the opportunity to purchase the blue uniform polo shirts and grey PT shirts during the first week of class.
