Of Counsel:

Harold W. Pskowski has been practicing law in Maryland and Washington D.C. since  1984, when he moved from the Boston area.  His wife, who is a Montgomery County native, persuaded him to make the move and he has not regretted it.  His practice focuses on trusts and estates, including planning for persons with special needs and their families.  He can advise clients on how to preserve assets for the use of a loved one with a disability, while still qualifying the beneficiary for government assistance and creating a structure for his or her long-term care. Although he believes that family needs are paramount when advising clients, his tax background enables him to advise on the tax implications of client planning and how taxes can be minimized.
