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 25 years our attorneys have protected the rights of workers and have spoken for the victims harmed by substandard medical care, defective products, and unsafe work places. We represent people who have been injured in auto accidents, construction site accidents, as a result of medical negligence, and through exposure to harmful substances such as asbestos, silica, lead paint, or defective products. Our attorneys are at the top of their profession and offer unparalleled legal representation. We have easily accessible offices in Virginia, Maryland, and D.C.

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 have founded a law firm 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.

Koonz, McKenney, Johnson & DePaolis LLP provides our clients with the highest level of competent, personalized legal representation available in the Washington, D.C. metropolitan area. Each Maryland, Virginia and Washington DC personal injury lawyer at our firm has developed the knowledge, resources, and contacts to handle large, complex cases without losing the personalized commitment of a small, hometown law firm.

Koonz, McKenney, Johnson & DePaolis LLP has offices in Fairfax, Virginia, Greenbelt, Maryland, and the District of Columbia. Our work in the courts of all three jurisdictions has established our attorneys as aggressive representatives of our injured clients. We are, first and foremost, a firm of trial lawyers who vigorously pursue claims of injured people in the local and federal courts in all three jurisdictions.

The attorneys of Koonz, McKenney, Johnson & DePaolis LLP pride themselves on making our community a safer place to live and raise our children through our aggressive representation of injured people. Through our efforts, we have protected consumers from future injuries by forcing corporations to change the design of defective products and to alter harmful conduct. As a result, we believe we have made our community a better place for everyone.
