About Our Law Firm

Upholding Justice For You In And Around Our D.C., Fairfax, And Greenbelt, MD Offices

The law firm of Koonz McKenney Johnson & DePaolis LLP represents clients from Virginia, Maryland, and the District of Columbia in all aspects of personal injury litigation. For over 30 years, each lawyer at our firm has protected the rights and spoken on behalf of workers and victims harmed by substandard medical care, motor vehicle accidents, and unsafe workplaces.

During our history, we have strived to better the laws that protect the rights of victims by providing quality legal representation to those injured in car accidents, construction accidents, as a result of medical malpractice and through exposure to harmful substances, such as asbestos, silica, and lead paint. Our D.C., Maryland, and Virginia injury attorneys are at the top of their profession and offer unparalleled legal representation in and around the metropolitan area.

About Our Legal Team

The founding partners, Joseph H. Koonz, Jr., Carolyn McKenney, and Roger C. Johnson began this firm in 1979 with a shared goal of aggressively defending the rights of individuals. We are dedicated to representing injured people, one client at a time.

In keeping with this goal, we do not represent insurance companies or corporate clients. Rather, we exclusively represent individuals who have been injured through no fault of their own, including those entitled to workers’ compensation or Social Security disability benefits.

Our Washington, D.C., Virginia, and Maryland personal injury attorneys pride themselves on making our community a safer place to live and raise our children.
