Client Feedback, Chambers USA 2023


With the straightforward outlook of a native Midwesterner, Marnie is a litigator who also advises on food and agricultural regulatory matters, protecting businesses that have often been in the family for decades.

While her litigation practice emphasizes food systems companies, Marnie represents clients in a variety of industries in complex commercial matters. Clients look to her for successful representation in bet-the-company litigation and other high-profile cases: Marnie often handles breach of fiduciary duty and breach of contract claims, trade secret claims, intellectual property issues, unfair competition allegations and shareholder disputes.

Alongside her winning record, she’s also known for a practicality that serves clients well. Marnie approaches litigation with an eye toward the outcome that will truly serve a client’s business. Her aim is not to have a lengthy court battle, but to solve the client’s real-world problem.

A respected name in food and agricultural regulations, Marnie also chairs the firm’s Food Safety & Regulation practice group. She advises clients on USDA and FDA regulatory matters, providing proactive counsel and advice on matters such as safety and labeling concerns, product recalls and inquiries from regulatory bodies. With nearly twenty years of experience in these areas, Marnie understands the issues unique to food and agribusiness.

The firm’s authority on the National Organic Program, Marnie is also well versed in the special requirements of organic food. She represents both organic-certification agencies and certified operations, and advises clients on compliance. 

What Marnie loves most about her work, however, is collaborating with clients: she often represents businesses that have been owned by several generations of the same family. She values the opportunity to serve clients who have such a strong emotional connection to their work and who truly love the businesses she’s protecting.
