David recently relocated from California with his wife, Lynn, a research scientist and native New Englander.  They enjoy traveling, hiking, and cooking together, and they appreciate that the sailing winds of the Charles River are calmer than on San Francisco Bay.

In his pro bono practice, David has advised several individuals in immigration proceedings and disputes over public benefits.  David also has advised community organizations on non-profit corporate and tax matters and environmental and land use regulations.
