Mr. Nelson has been practicing law since 1981 and has had his own firm since 1997. The firm handles environmental and landuse cases for citizens. It also litigates matters in areas such as professional malpractice, contract disputes, property disputes, admiralty, negligence, product liability and other torts.

  The firm's land use and environmental practice has served citizens and community associations in urban, suburban, and agricultural areas. On these clients' behalf, the firm has litigated the enforcement of water quality, wetlands, forest preservation, noise and air quality regulations; the siting of rubblefills and quarry uses; the pollution of urban neighborhoods by industrial facilities; the development of rural land for non-agricultural uses; and the introduction of high-density uses in suburban neighborhoods. Additionally, the firm selectively handles medical malpractice and personal injury cases for plaintiffs.

The firm continues its representation of clients throughout the state in administrative proceedings and in the trial and appellate courts. The Maryland Court of Appeals, the state's highest court, has recognized the importance of our cases by deciding to review six of our cases in the last two years. We are especially proud of our December 2009 victory in the Maryland Court of Appeals where the Court accepted our argument that the Prince George's County's Planning Board must consider the requirement in the County's General Plan that no more than 1% of all residential development in the County may occur in the County's Rural Tier. We also continued to represent clients in medical malpractice, personal injury cases, and other civil matters throughout the state.
