ABOUT US

The All County Security Agency, Inc. was first established in 1989 by former Howard County Police Officer, Charles Ellenberger. Through his personal experiences as a veteran officer of the Howard County Police Department, Mr. Ellenberger realized firsthand the incumbent need for private security. Maintaining an undying loyalty to Howard County and its residents, the All County Security Agency established its corporate offices in Ellicott City, Maryland. 

Hand-selecting a veteran team of security and investigation professionals, Mr. Ellenberger leverages far-reaching industry contacts and knowledge of client security needs to continually develop a dedicated team of individuals drafted from a wide variety of legal and law enforcement backgrounds. Through on-site training and continuous professional development, our diverse staff of men and women is consistently prepared to meet and exceed the highest standards of our clients. Overall, the All County Security Agency team encompasses more than 150 years of proven, industry-leading experience in security, military, and law enforcement. 

All County Security Agency is currently responsible for providing their services at government buildings, apartment complexes, medical facilities, schools, health clubs, athletic events, fairs, business parks, and many more. We currently have a staff of over 100 security personnel working on a full and part-time basis. We are able to provide up to 75 security personnel for fairs and special events, and as little as one employee for a small site.
