We advocate for you
A criminal conviction in Massachusetts or federal court can mean prison, deportation, professional disbarment, and permanent loss of firearms and licensing rights. Prosecutors and agents build cases during the investigative phase—before you ever see an indictment—and early missteps in interviews or document production often become the evidence at trial. The window to shape charging decisions, preserve suppression issues, and coordinate parallel regulatory exposure closes quickly once the government commits to a theory. Federal cases in Boston follow the U.S. Sentencing Guidelines, pretrial detention under the Bail Reform Act, and discovery obligations that differ materially from state practice. Wire fraud, public corruption, narcotics conspiracies, and firearms charges often arrive with voluminous electronic evidence and parallel regulatory investigations. Early counsel coordinates with state proceedings, licensing boards, and civil exposure. Preservation for First Circuit appeal begins at the plea colloquy and sentencing hearing—not after judgment enters. Denner Lamanna follows a disciplined process—Immediate intake & privilege review: We assess exposure, identify parallel civil and licensing consequences, and establish attorney–client protocols before any government contact or internal investigation proceeds. Investigation response: Grand jury subpoenas, search warrants, target letters, and agent interviews are handled with document preservation, witness strategy, and proffer evaluation where appropriate. Pretrial motion practice: Suppression, discovery, and evidentiary motions define what a jury will hear—especially in white-collar, firearms, and public-corruption matters with complex records. Trial or negotiated resolution: We staff for jury trial in Massachusetts Superior Court, District Court, and the District of Massachusetts—with sentencing and restitution planning integrated from the first case conference. Sentencing, appeal & collateral: Guidelines advocacy, First Circuit and Massachusetts appellate review, and coordination with licensing, immigration, and civil proceedings that outlast the criminal case. Institutional defendants and opposing counsel deploy delay, denial, and resource advantages. Criminal defense matters deserve trial-ready counsel from Boston who builds for courtroom advocacy—not volume docket management.

In depth
Educational overview of local law, data, and litigation context—not legal advice for your specific situation.
Massachusetts divides most criminal matters between District Court (misdemeanors and some felonies) and Superior Court (serious felonies and mandatory Superior Court jurisdiction). Arraignment, bail, and conditions of release are often decided in the first 72 hours—before clients fully understand how statements, text messages, and social media will appear at trial.
Discovery reform and open-file practices vary by district attorney's office, but prosecutors still control charging decisions, grand jury presentations, and plea offers. Denner Lamanna engages when leverage still exists: before indictments harden theories, before proffers waive defenses, and before probation surrender or violation hearings add exposure.
Federal cases in Boston follow the U.S. Sentencing Guidelines, pretrial detention under the Bail Reform Act, and discovery obligations that differ materially from state practice. Wire fraud, public corruption, narcotics conspiracies, and firearms charges often arrive with voluminous electronic evidence and parallel regulatory investigations.
Early counsel coordinates with state proceedings, licensing boards, and civil exposure. Preservation for First Circuit appeal begins at the plea colloquy and sentencing hearing—not after judgment enters.
Overview
Denner Lamanna represents clients when freedom, reputation, and enterprise value are on the line. Based in Boston, the firm appears in Massachusetts state courts, the District of Massachusetts, and appellate forums nationwide where licensing rules permit coordinated advocacy.
We accept complex, high-stakes mandates where we can walk beside a client for the full timeline—from the first sign of an investigation through trial and appeal. When we cannot undertake representation, we aim to give candid guidance about risk, timing, and next steps.
Massachusetts prosecutions move quickly once an investigation becomes public. Early counsel can help preserve evidence, manage interviews, shape charging decisions, and position pretrial motions before the government commits to a theory of the case.
Many consequential criminal cases are won or lost before an indictment exists. Grand jury practice, search-warrant returns, and voluntary interviews create records that define trial—and appellate—issues for years. Denner Lamanna engages early when clients face white-collar, corruption, or violent-crime exposure in Boston and across Massachusetts.
Effective criminal defense requires appellate standards in mind from the first motion. Our team includes counsel admitted to the First Circuit and experienced before the Massachusetts Appeals Court and Supreme Judicial Court—so preservation is built into trial strategy, not added after conviction.

FAQ
Common questions about criminal defense in Massachusetts and federal court.
As early as possible—ideally at the first sign of an investigation, search warrant, grand jury subpoena, or arrest. Early counsel can influence charging decisions and preserve issues for trial and appeal.
Yes. The firm appears in the U.S. District Court for the District of Massachusetts and handles First Circuit appeals alongside Massachusetts state criminal matters.
High-stakes cases typically involve significant prison exposure, professional licensing, business continuity, media attention, or parallel civil and regulatory proceedings that must be coordinated from day one.
Almost never. Statements made during an investigation are among the most common sources of conviction evidence—and waivers of rights are difficult to undo. Consult counsel before any voluntary interview.
Federal cases in the District of Massachusetts follow different rules, sentencing guidelines, and discovery obligations than Massachusetts state court—and pretrial detention is more common. Forum and charging decisions are strategic questions we address at intake.
Yes. Pre-indictment counsel is often the most consequential phase—when charging decisions, cooperation posture, and document production strategy can still be shaped.
We accept appellate mandates directly and also carry cases from investigation through trial and First Circuit or Massachusetts appellate review.
Criminal exposure often triggers professional licensing, immigration, firearms, security clearance, and civil liability. We coordinate strategy across forums from the first meeting.
