William Andrews
Chief Security Advisor
My name is William Andrews, and I am the founder and CEO of Andrews Comprehensive Security Services. I am a man of faith, putting God first in my life. I am a family man. My beautiful wife and I have three amazing daughters and three incredible grandchildren.
I am a veteran of 31 years, having served in the United States Marine Corps, the United States Army National Guard and the United States Air Force. I retired in 2021 as a Chief Master Sergeant with four tours to the Middle East in support of Operation Enduring Freedom and Operation Iraqi Freedom.
I am also a police officer with 27 years of experience with over 10 years in the Community Services sector. As a Community Engagement Officer, I’ve become passionate about instructing citizens, businesses and organizations on Active Shooter Response Training. Our mission at Andrews Comprehensive Security Services is to instill knowledge and understanding that will enhance your survivability during a crisis. Understanding these qualifications are reasons for why I am qualified to help lead your business with the best security system and program available to your community.
