Inquire About Your Matter

We have the knowledge, experience, and networks to guide your business through your local legal challenges. We are DC residents and business-owners, and we are ready to help you.

Our Philosophy



Our attorneys know D.C. law. We draft legislation that becomes law, represent employers before the EEOC and D.C. Office of Human Rights, advise public-private partnerships, and assist with multiple types of financing mechanisms including TIFs and tax abatements. We stay current on all areas of the law which we cover. Our attorneys work closely with District government agencies, and can advise your company how to work with our local government.



Our attorneys have represented hundreds of local businesses and Fortune 100 corporations in complex and high-stakes real-estate transactions, in federal and local court, before the D.C. Council and a multitude of District agencies, and candidates in the highest profile local political campaigns. Our attorneys have logged hundreds of hours helping individuals, nonprofits, and businesses to navigate the myriad complexities of District government regulations. Our professional staff has years of hands-on experience assisting attorneys with all facets of the legal profession.



Almost half of our staff have worked at high levels within the Executive and Legislative branches of the District of Columbia government. We maintain excellent working relationships with the District’s Mayor and Councilmembers, as well as appointed agency directors and staff. In addition, we strive to build strong relationships with our current and former clients and participate on numerous public policy, community, charitable, and legal boards of directors.
