Martin G. Weinberg

For more than 40 years, Weinberg has provided his clients with skillful and dedicated counsel in many of the most challenging criminal law cases of our times. 

Award-Winning Defense

When the government pursues a criminal case, the burden rests on them to prove beyond a reasonable doubt that the defendant is guilty. This requires collecting and presenting evidence; however, not all evidence the prosecutor has is strong, and in some instances, it might have been unlawfully detained.

In a recent book, "Unacceptable: Privilege, Deceit & the Making of the College Admissions Scandal Hardcover", by Melissa Korn and Jennifer Levitz, Attorney Martin Weinberg is described as, "one of the most well-respected trial lawyers in Boston. Weinberg had done solely defense since graduating from Havard Law almost fifty years earlier. Known as fiercely intelligent, he tackled tough white-collar and criminal cases, from political corruption to murder."

At Martin G. Weinberg, Attorney at Law, when we take on a case, we are diligent and detailed-oriented, examining every bit of evidence and thoroughly reviewing the manner in which it was obtained. If any injustices occurred during the process, we are not afraid to challenge the government and work toward rectifying constitutional violations. Our Boston federal defense lawyer will develop a unique legal strategy for your case.
