Our Columbus Office

Ohio security clients are cared for primarily by our metro Detroit branch office, which is a hub of operations for all east Michigan and Buckeye State partners. Ohio has full access to our services with support from Detroit—but who knows… a DK office could be coming to Columbus in the future!

In addition to security management and response, the DK – Troy team is equipped to perform fingerprinting services and receive employees for new hire orientations.

One Company, One Solution

Uniformed Security

Our longest-serving area of service, the DK uniformed security division is our company’s largest and serves a variety of Columbus industries. DK carefully screens and trains all unarmed guards to serve the government, energy, education, manufacturing, healthcare, and entertainment sectors, among others. We provide security guard services in Columbus, Ohio to a wide range of organizations and thoughtfully evaluate every security request we receive.

Armed Security

We offer armed security in Columbus, Ohio in addition to our standard uniformed staff. All Ohio-based DK armed staff are licensed to carry firearms and are highly trained to respond in times of threat or emergency. Especially for high-risk organizations in education, healthcare, government, and cannabis, we encourage you to inquire about whether armed security is right for you.

Event Security

Covering duties similar to those of uniformed security guards, DK event staff are assigned to protect entertainment venues of all shapes and sizes. Our event team serves the smallest of gatherings all the way up to multi-day events attended by 100,000+ guests.

Why Us

Why Choose DK Security?

Our nearly 30 years of security expertise started as the idea of two accomplished federal law enforcement leaders: Bob DuHadway and John Kendall. Together, they built DK into a trusted and reputation-driven company that ranked among the nation’s 50 largest security providers even before expanding beyond Michigan. 

Today, we are proudly woman-led, WBENC-certified, and provide the Columbus business community with the same high-quality client support the “D” and “K” of DK were known for. On the individual level, each of our guards is carefully screened and trained to ensure the highest standards of hospitality and professionalism.

Whether you’re looking for a traditional uniformed security guard, background screening services, or to complete any number of custom security assignments, the range of services we provide is extensive and always backed by experience. DK Security is a full-service security provider, and we fulfill security requests of all shapes and sizes.
