About me

Leonard Stamm wrote the book on Maryland DUI Law.  He has been a
practicing drunk driving, DUI, DWI, and criminal defense lawyer in the
District, Circuit, and

appellate courts of Maryland

since 1984.  Since 1991,
after the death of his partner, Alan J.
, he has maintained a practice, under the name of
Goldstein & Stamm, P.A., in Greenbelt, Maryland, representing individuals
accused of crimes and traffic offenses in state and federal courts,
primarily in Montgomery (Rockville and Silver Spring), Prince George's
(Upper Marlboro and Hyattsville), Howard (Ellicott City), Anne Arundel
(Annapolis and Glen Burnie), Calvert (Prince Frederick), Charles (La
Plata), and St. Mary's (Leonardtown) counties. Stamm
also handles cases in Baltimore City, Baltimore County, Caroline (Denton), Frederick, Kent
(Chestertown), Queen Anne's (Centreville), and Talbot
(Easton) counties, and has handled cases in
Dorchester, Garrett,
Harford, Washington,
Wicomico, and Worcester counties.  Stamm handles
appeals in the Maryland appellate courts, and is admitted to practice
before the United States Supreme Court.  In early 2004,
Andrea Hayduk joined the firm as
an associate attorney also focusing on drunk driving, DUI, DWI, and
criminal cases in the District, Circuit, and appellate courts of Maryland. 
In early 2008, Ms. Hayduk relocated to her home in Tennessee and was
replaced by Johanna Leshner.

Stamm is
recognized as an authority in the area of drunk driving defense and
Motor Vehicle Administration hearings in Maryland and has lectured and
written extensively in this area, in Maryland and around the country.
He has been a speaker at and has organized
numerous continuing legal education seminars since 1986.  He is
presently a Regent of the National College for DUI Defense, serving on its Amicus Committee,
and is former President of the Maryland Criminal Defense Attorneys'
.  He also serves on the Maryland Criminal Pattern Jury
Instruction Committee of the Maryland State Bar Association.  He has had a
number of articles published in the Champion magazine, the magazine of the
National Association of Criminal Defense Lawyers
He has been qualified as a practitioner and an
instructor in standardized field sobriety tests in
accordance with standards set forth by the International Association of Chiefs
of Police (IACP)
and the National Highway Traffic Safety Administration (NHTSA) and completed a certification class as an operator and maintenance technician
for the Intoxilyzer 5000.  He recently hosted a training seminar in the
Intox EC/IR.  Stamm holds a certificate of successful
completion for the Robert F. Borkenstein Course on "Alcohol, Drugs, and
Highway Safety: Testing, Research, and Litigation
" based out of Indiana
University at Bloomington.  He is one of the few lawyers in the country to have taken a two and a half day
overview of the Drug Recognition Expert (DRE) program. 
Martindale-Hubbell gives him an "AV" rating. 
He has also been listed in "Super Lawyers" and "Best Lawyers." 
In September 2008, the first edition of Stamm's book,
Maryland DUI Law, was
published by West Publishing Company.


Stamm's philosophy in drunk driving (DUI/DWI) defense is that unless the
State is offering a plea that is significantly better than going to trial and
losing, there is no good reason to plead guilty and not go to trial.  In
drunk driving cases, unlike many other charges in state court, more often then
not there is very little if any benefit to pleading guilty.  As a result he
prepares every DUI/DWI case for trial.  This is different from the vast
majority of other lawyers who will assume they cannot win your case and plead
you guilty.
