Firm History

In 1968, Joseph S. McCarthy and James T. Wharton established the Law Offices of McCarthy and Wharton, with their two main clients, Erie Insurance Company and Allstate Insurance Company, both of which remain clients of the firm today.  Over the first 10 years, while housed in a historic property at 100 South Washington Street in Rockville, Maryland, the firm saw significant growth, adding attorneys and expanding its office by acquiring the adjacent historic property at 104 South Washington Street.  In 1998, after another 20 years of significant growth and practice expansion, the firm acquired another adjacent historic house at 108 South Washington Street, and these three Victorian properties served as the firm’s principal office over that forty year period.


In 2007, the firm opened offices in Baltimore consistent with the Mid-Atlantic regional expansion of the practice. The Baltimore office is located directly behind the circuit courthouse in the elegant Van Sant Building at 210 East Lexington Street, Suite 300, in Baltimore City.  These offices have already expanded in both size and capacity to support of the continuing overall growth of the firm.


In 2008, the McCarthy Wilson LLP proudly announced the relocation of its Rockville office to the new ASHA Executive Building, a brand new state-of-the-art LEED Gold-Certified Green Building, located at 2200 Research Boulevard, Suite 500, in Rockville, Maryland.  In addition to superior, integrated and technologically advanced office space, our new office features outstanding conference facilities, which will assist our continuing work in such areas as complex mediations, arbitrations, multi-party depositions, mock trials, jury analysis and continuing legal education seminars.  The Rockville office continues to serve as the principal office of the firm.


McCarthy Wilson LLP is now comprised of approximately 25 lawyers and over 50 highly skilled legal support personnel, working on cases in the state and federal trial and appellate courts of Maryland, Virginia and the District of Columbia, from our Rockville and Baltimore locations. As our numbers, practice areas, and legal expertise have increased, so has our ability to handle a broad range of cases for large and small clients throughout the region and across the nation.


As we celebrate our 40th year of dedicated service to our clients and our profession, we invite you to contact us should you have any questions or require any information with regard to your legal needs. It has been our pleasure serving our community throughout our storied history, and we look forward to the opportunity of working with you in the future.
