Karen A. Leiser

Phillip Leiser

Managing Partner



Karen started her legal career as a staff attorney at Legal Services of Northern Virginia (LSNV) from 1997 to 2002, where she worked in the areas of housing and family law. She served as the Managing Attorney for the Fairfax branch of Legal Services from October 2000 through July 2002. She joined her husband’s law firm in 2002, as his Managing Attorney, where she has continued her practice in the areas of family law, landlord and tenant, and branched out into handling cases in other areas, including criminal and traffic defense and personal injury. Ms. Leiser has successfully argued cases before juries and on appeal to the Virginia Court of Appeals and has also presented cases before the Virginia Supreme Court. In one case, after the trial court refused to award her client any retirement benefits, Karen was able to convince the Virginia Court of Appeals to reverse the trial court’s ruling, and thereby obtained a significant portion of the husband’s retirement benefits for his wife of 27 years, after the husband stopped working early due to a disability.  For the full court opinion, follow this link.
