About Mitzi Ng Clark

Mitzi Clark advises domestic and international corporations on a wide range of food, cosmetic, and drug packaging regulatory issues, ranging from U.S. Food and Drug Administration (FDA) premarket clearance requirements for food contact materials and local and state regulations concerning plastics and chemicals, to good manufacturing issues and regulatory requirements for food, alcoholic beverages, cosmetics, and animal feed. Mitzi’s practice extends to the international arena, where she regularly counsels clients on regulatory matters in jurisdictions such as Asia, Canada, the European Union (EU), Latin America, Africa, and the Middle East.

Mitzi began her legal career at Keller and Heckman in the firm’s Washington, DC office where she experienced firsthand the mechanics of U.S. regulatory agencies. Recognizing the need for food contact expertise on the West Coast, she relocated in 2018 to Keller and Heckman’s San Francisco office, which she currently manages. Since her time in San Francisco, Mitzi has helped numerous companies understand the nuances of various state and local laws and regulations, including California’s Proposition 65, A.B. 1200 on Plant-Based Food Packaging and Cookware, the Plastic Pollution Prevention and Packaging Producer Responsibility Act (SB 54), the Rigid Plastic Packaging and Container Program (RPPC), and the State’s plastic bag legislation.

While in law school, Mitzi served as the executive editor of the Temple Environmental Law and Technology Journal. Before attending law school, Mitzi received a Master's in Public Health. Coupled with her scientific background in cancer research, Mitzi’s experience in public health and epidemiology brings a unique technical perspective to complex regulatory matters.

Mitzi has contributed to various trade publications, including Food Packaging Bulletin, Plastics Recycling Update, and FLEXO Magazine, as well as packaginglaw.com . She is frequently invited to speak at domestic and international conferences and has presented on topics related to food contact regulatory matters, recycled plastics, and California’s Proposition 65 and other state-related legislation.

It is solely the responsibility of lawyers and law firms to ensure that any information they provide complies with all applicable laws and rules of professional conduct.

Lawyers.com Client Reviews

Martindale-Hubbell® Client Review Ratings™ display reviews submitted by individuals who have either hired or consulted the lawyers or law firms.

The Client Review Rating score is determined through the aggregation of validated responses. People who submit reviews are either individuals who consulted with the lawyer/law firm or who hired the lawyer/law firm and want to share their experience of that lawyer or law firm with other potential clients. Reviewers can be anyone who consults or hires a lawyer including in-house counsel, corporate executives, small business owners, and private individuals.

Martindale-Hubbell validates that a reviewer is a person with a valid email address. As part of the review process, respondents must affirm that they have had an initial consultation, are currently a client or have been a client of the lawyer or law firm identified, although Martindale-Hubbell cannot confirm the lawyer/client relationship as it is often confidential. The content of the responses is entirely from reviewers.

Prior results do not guarantee a similar outcome and Martindale-Hubbell accepts no responsibility for the content or accuracy of any review. For more information on Martindale-Hubbell Client Review Ratings, please visit our Client Review Page

Martindale Peer Reviews

Martindale-Hubbell® Peer Review Ratings™ are the gold standard in attorney ratings, and have been for more than a century. These ratings indicate attorneys who are widely respected by their peers for their ethical standards and legal expertise in a specific area of practice.

The Martindale-Hubbell Peer Review Ratings process is the gold standard due to its objectivity and comprehensiveness. Lawyers solicited for peer reviews include both those selected by the attorney being reviewed and lawyers independently selected by Martindale-Hubbell. All reviewers are verified as attorneys through Martindale-Hubbell’s extensive attorney database. Only attorneys practicing at least three years and receiving a sufficient number of reviews from non-affiliated attorneys are eligible to receive a Rating.

What are the different Martindale-Hubbell Peer Review Ratings?*

• AV Preeminent®: The highest peer rating standard. This rating signifies that a large number of the lawyer’s peers rank him or her at the highest level of professional excellence for their legal knowledge, communication skills and ethical standards.

• Distinguished: An excellent rating for a lawyer with some experience. This rating indicates the attorney is widely respected by their peers for high professional achievement and ethical standards.

• Notable: This rating indicates that the lawyer has been recognized by a large number of their peers for strong ethical standards.

Lawyers who have received peer reviews after 2009 will display more detailed information, including practice areas, summary ratings, detailed numeric ratings and written feedback (if available). Details for individual reviews received before 2009 are not displayed.

Attorneys that receive reviews from their peers, but not a sufficient number to establish a Martindale-Hubbell Peer Review Rating, will have those reviews display on our websites.
