Gregg H. Hilzer

Gregg H. Hilzer is a partner at Pashman Stein Walder Hayden who focuses his practice on cannabis law, white-collar criminal investigations, complex litigation and regulatory matters.

Gregg is co-chair of Pashman Stein’s Cannabis & Hemp Law practice group. Recognized on the InsiderNJ “Insider 100: Cannabis Power List” in 2022 and 2021 as an influential voice in the cannabis debate, Gregg has experience advising existing medical marijuana operators and representing applicants poised to enter various aspects of the medical marijuana industry. In both the medical marijuana and hemp spaces, he provides multifaceted legal guidance to business entities and individuals focused on managing risk and ensuring compliance with regulatory requirements. 

Gregg’s experience also includes complex litigation matters on behalf of financial institutions, multinational corporations, public entities, small businesses, and individuals. A highly skilled litigator, he has successfully represented a wide range of clients in the state and federal courts of New Jersey and New York. He also has substantial experience representing clients before various regulators, including the New Jersey Department of Banking and Insurance, New Jersey Board of Medical Examiners, and New Jersey Office of Attorney Ethics. His white-collar experience includes defending matters involving allegations of bank, tax and healthcare fraud; commercial bribery; and violations of the False Claim Act. He is also regularly called upon to evaluate his client’s policies and procedures to ensure regulatory compliance and effective risk management.

Along with Pashman Stein partner Raymond M. Brown, Gregg was a member of the legal team that successfully defended U.S. Senator Robert Menendez in Federal District Court against unfounded allegations of public corruption and bribery brought by the federal government. The trial ended in November 2017 with a hung jury and subsequent mistrial.  Shortly thereafter, the Department of Justice dismissed all remaining charges against Senator Menendez.

While in private practice, Gregg also earned his LL.M. in Banking, Corporate & Finance Law, where he was ranked first in his class with a concentration in government investigations and securities regulation.

Upon his graduation from law school, Gregg served as law clerk to The Honorable David B. Rand in the Morris County Superior Court.

Gregg is proud of the results he has achieved for clients, some of which are noted here and under the “Experience” section of this biography.  Of course, each legal matter is unique on many levels, and past successes are not a guarantee of results in any other pending or future matters.
