Milton Grunwald, Esq.



Milton Grunwald, Esq.

Nassau County Criminal Defense Attorney

In over 35 years of practicing law, Milton Grunwald has tried all kinds of civil, commercial, estate and criminal cases.

As a law student at St. John’s University, he won the Sporacio Trial Competition as the best advocate at the law school. He went on to represent St. John’s in the National Trial Competition, defeating such prestigious Law Schools as Yale and NYU.

After St. John’s Law School, Milt Grunwald went to the Nassau County District Attorney’s Office in Mineola, New York. He served with distinction in his three years in the Office of Denis Dillon, rising through the ranks to the County Court Trial Bureau and serving as the Chief of the Mental Health Unit. He tried over 21 cases to verdict in three years, including:

  • Robbery
  • Burglary
  • Narcotics and drug cases
  • Drunk driving
  • Driving under the influence of drugs
  • Drunk driving by a refusal to take a breathalyzer test
  • Suspended licenses
  • Assault
  • All types of larceny cases (from petit larceny to grand larceny)
  • Forgery

As a prosecutor, Milton Grunwald worked in felony screenings and the Grand Jury. He presented direct evidence in grand jury presentments and at hearings such as Dunaway, Wade, Huntley, Mapp, Gomberg, and Sandoval. He understands the art of arranging and presenting evidence in its simplest and most logical form. Over the years, Attorney Grunwald has developed keen cross-examination techniques, as well as learned the language of the science involved in ballistics, fingerprints, blood serology, and forensic pathology.

In 1988, Milton Grunwald formed the law firm of Grunwald & Seman with Karl Chip Seman, his partner in the DA’s office. They embarked on a legal career that provides a hard-nosed, relentless, and successful representation of their clients.

In over 35 years of practice, Milton Grunwald has defended men and woman accused of murder, manslaughter, robbery, burglary, drug possession, drug sale, forgery, possession of forged instruments, commercial fraud, drunk driving, driving under the influence of drugs, drunk driving by refusal, license revocations, endangering the welfare of a child, internet crimes, assault, criminal mischief, menacing, harassment, aggravated harassment, sexual abuse, rape, larceny, and state liquor law violations.

As Nassau County, with the election of Kathleen Rice, has focused on the harsh prosecution of drunk driving cases, the firm has emphasized the defense of such matters. Their expertise is critical when reviewing breathalyzer logs, equipment logs, field sobriety performance tests, videotaped refusal tests and the impact of controlled substances on the motorist. As a consequence of handling such drunk driving cases, Attorney Grunwald has also worked hard and mastered the issues involved in the area of civil forfeiture of cars for those individuals arrested for drunk driving.

In addition, Attorney Grunwald has handled and developed an expert niche in trying complex commercial litigation including partnership and corporate dissolutions. The cases have covered industries such as real estate companies, architectural firms, the lighting and construction industry, insurance companies, fire extinguisher companies, and the auto industry. The cases have litigated issues with tens of millions of dollars at stake.

A graduate of the NYU Graduate School of Public Administration, Milt Grunwald worked for two years as a hospital administrator at the Bronx Municipal Center [Jacobi Hospital]. His relationship with doctors, nurses, hospital administrators, physical therapists, and chiropractors lead to the development of a practice that includes the commercial and civil concerns of professionals in the health care field. His litigation practice and the skills developed as a trial attorney has provided his clients with the necessary edge to present their case in the most favorable light. Additionally, Attorney Grunwald’s criminal defense background has also helped several practitioners who faced disciplinary action by the Department of Education, Board of Health and Office of Professional Medical Conduct.

In 2003, Milt Grunwald was elected the Village Justice of Roslyn, where he has lived for over twenty years. He hears all types of building matters and traffic cases. He has presided over trials involving the most common issues such as speeding to parking violations and as complex as landowner and municipal liability. See People v. Brian Witthun [Distinguishing the language of unreasonable speed under 1180a of the Vehicle and Traffic Law].

Milt Grunwald is a graduate of the St. John’s School of Law in Jamaica, New York, The NYU Graduate School of Public Administration in Washington Square, New York, Brandeis University in Waltham, Massachusetts and Abraham Lincoln High School in Brooklyn, New York.
