Attorneys you can trust to fight for you. Experienced and aggressive representation you can count on.

Our Firm

Diligence, persistence, and preparation are the keys to our successful litigation practice.


Mr. Sher started his career as a prosecutor for the Arlington County Commonwealth Attorney’s Office and is famous for his dogged prosecution of a “cop killer”, as well as other serious felonies. One of his notable civil cases was against the Federal Republic of Germany on behalf of a Holocaust survivor.



Mr. Cummings began his career representing W. Mark Felt in the FBI civil rights conspiracy trial, and also worked toward the subsequent pardon by President Reagan. Mr. Cummings has been consistently recognized as an outstanding trial lawyer by his peers and legal publications.



After years of practice in the areas of civil and criminal litigation, David Sher and Mark Cummings formed Sher & Cummings in 1983.  In 2003, Mr. Sher and Mr. Cummings were joined by John Ellis, a renowned medical malpractice attorney, and the firm changed its name to Sher, Cummings and Ellis. Like any successful organization, it is the attorneys of Sher, Cummings and Ellis who make the firm exceptional. Our attorneys have represented individuals in multi-million dollar lawsuits involving wrongful death, personal injury, defamation, attorney malpractice and fees disputes, as well as various criminal matters ranging from DWI to murder.


Grace has a background in complex criminal litigation, investigations, and employment law. She currently focuses her practice on criminal and civil litigation in Virginia state courts.

Our partners have been practicing law since the 1970’s, and for the past 33 years, Sher, Cummings and Ellis has focused on providing the highest caliber representation for our clients. We treat our clients like they are part of the family, and as a result, most of our work comes from referrals of past clients. We are dedicated and responsive advocates who will work with you to achieve the best possible result in your case. Over the years, our attorneys have been recognized for their professional expertise. Both David Sher and Mark Cummings are AV rated by Martindale Hubbell, and have been selected yearly for Super Lawyers recognition since 2007 and 2008, respectively. They have also been recognized in the Washingtonian Magazine’s Top Criminal Defense Attorneys List.
