Criminal Defense Lawyers
Stahl Gasiorowski Criminal Defense Lawyers is a highly successful criminal defense firm with offices in Mountainside, NJ and Manhattan, N.Y. For more than 30 years, we have represented individuals and corporations in federal investigations and criminal charges throughout the United States, and in state courts in New Jersey and New York. We are a small firm devoted exclusively to serious criminal and regulatory matters.
Federal and State White-Collar Criminal Defense
Stahl Gasioroski specializes in defending those accused of white-collar crimes: healthcare fraud, financial frauds (bank fraud, mortgage fraud, securities fraud), computer fraud and ransomware, wire and mail fraud, foreign currency transactions, criminal tax evasion, money laundering, cryptocurrency fraud, and Ponzi schemes. We also represent clients charged with complex criminal conspiracies such as RICO, CCE, and VICAR offenses. In addition to criminal matters brought by U.S. Attorney Offices, Department of Justice, and District Attorneys, we also handle matters involving the SEC, FINRA, FDA and other government regulatory agencies. Our clients include accountants, dentists, physicians, pharmacists, pharmacy sales representatives, lawyers, corporate executives, brokers, financial planners, builders, as well as publicly traded and privately held companies, partnerships, and investment funds.
Federal and State Defense
Our lawyers are experienced in defending against allegations involving extortion, kidnapping, narcotics trafficking and other drug offenses, firearm offenses, identity theft, domestic violence, sexual assault, physical assault, credit and debit card fraud, and serious motor vehicle offenses such as DUI, death by auto and eluding.
Internal Corporate Investigations
Stahl Gasiorowski also oversees corporate investigations for small to midsize companies involving insider-trading, corporate malfeasance, employee and trade secret thefts, cybercrimes, and employment issues. As a former Assistant U.S. Attorney for the District of New Jersey, Mr. Stahl has years of investigative experience uncovering and analyzing financial records, interviewing employees, and gathering evidence.
University and Student Disciplinary Matters
We represent university and college students accused of fraternity/sorority hazing, assault, underage drinking, sexual harassment and sexual assault, and code of conduct violations. These matters require a knowledge of the student-client’s rights, the disciplinary hearing process and the collateral consequences of cooperation or non-cooperation. In addition, university investigations often expose clients to criminal investigations and charges. We work to protect our student-clients’ rights in both the academic and law enforcement settings.
Success Through Experience and a Team Approach
The key to our success is exhaustive preparation, in-depth investigation, aggressive pre-trial motions, well-thought-out trial strategy and trial skills honed over more than three decades of practice. To level the playing field against federal and state prosecutors and agencies with unlimited resources, we employ a team approach. Each of our criminal defense attorneys has a unique set of skills and experiences. We work together to develop the best possible defense strategy. Our team looks for the flaws and weaknesses in the government’s case, whether it is in the facts or the law, to best position the defense of our clients.
Our firm also has a network of highly accomplished private investigators, forensic accountants, forensic psychologists, and experts across a wide array of disciplines to assist us. Many of our cases are complex, involving millions of documents, recorded conversations, and voluminous financial transactions. In these larger cases, bringing together a team of professionals has proven to be most effective and cost efficient in attacking the government’s theory of the case.
Why Us
When the stakes are high, clients count on Stahl Gasiorowski as the go to small firm for complex white collar criminal defense and investigations. Stahl Gasiorowski is small, but nimble, and as capable as much larger firms because we are leaner, with a laser focus on a singular practice: criminal defense. Keenly aware of the damage an investigation or prosecution can do to our client’s personal lives and families, their businesses and finances, and their reputations, partners Robert Stahl and Laura Gasiorowski work together and with clients to provide pragmatic, strategic and aggressive representation to individuals and corporations facing government investigations. The firm has a strong healthcare fraud practice concentrating on Anti-Kickback Statute cases and healthcare fraud involving medical devices (DME), pharmaceuticals (compounds and diversion); telemedicine and Medicare fraud schemes like CGX testing, bloodwork and screening schemes and up-coding. In addition to healthcare, the firm represents financial professionals charged with insider trading, securities fraud, and cryptocurrency frauds. Stahl Gasiorowski has also represented prominent public officials in public corruption and bribery cases.
Laura K. Gasiorowski and Robert G. Stahl are a formidable team – inspired, creative, experienced, driven, and relentless. Robert Stahl started his professional career in law enforcement, later becoming an attorney and working for years as an Assistant United States Attorney for the District of New Jersey. An accomplished trial attorney, he brings 35 years of experience and an insider’s knowledge of how white-collar criminal cases are initiated, investigated, and prosecuted. Where possible, he is adept at negotiating strategically to avoid prosecution, or to reduce exposure in a carefully crafted plea. When necessary, he is a formidable trial advocate known for his courtroom skills. Partner Laura Gasiorowski has been a criminal defense attorney for over 30 years in New York and New Jersey. She is a fierce advocate for her clients, combining detail oriented, proactive investigation with aggressive, creative, and incisive motion practice and courtroom advocacy. Known for thinking “out of the box” and for exquisitely crafted, powerful motions, appellate briefs and sentencing memoranda, Ms. Gasiorowski also has a deep reservoir of mitigation skills, crucial to her advocacy for clients, whether in obtaining a dismissal of charges, alternative resolutions, or sentencing practice.
The range and depth of the firm’s cases speaks about the firm’s reputation and abilities. In the past year, Stahl Gasiorowski has represented a deputy mayor of a large US city accused of bribery and corruption; a business owner and the business entity in a multistate multi-defendant federal prosecution for the transport, sale and processing of stolen catalytic converters and subsequent refining of precious metals for international sale, involving over $600 million in losses, and money laundering; and a marketing and sales director of a large lab with offices in New York and New Jersey charged with illegal kickbacks and healthcare fraud in relation to the payment of kickbacks to doctors and submission of medically unnecessary CGX cancer screening tests.
