Diance McEnroe has established long-standing relationships with domestic and international companies in the food, drug, medical device and personal care industries. As a member of the Food, Drug and Medical Device Regulatory practice, she provides clients strategic counsel on Food and Drug Administration regulatory questions on a broad range of issues, including product formulation and positioning, ingredient safety, claims substantiation, over-the-counter drug monograph issues, and post-marketing obligations, including adverse event reporting and food registry postings.

Diane also has extensive experience advising on drug sampling programs, track and trace systems, and state licensure issues. She supports clients in responding to Warning Letters, during facility inspections and recalls, and in addressing product integrity issues. In addition to her FDA advisory role, Diane has also assisted clients with Federal Trade Commission investigations relating to consumer products.

She regularly trains in-house counsel and regulatory teams on FDA compliance issues and assists companies in strengthening internal procedures to minimize compliance risks. In addition, Diane often leads FDA and FTC due diligence reviews for food and drug companies on behalf of major industry leaders and investment firms. She also closely coordinates with Sidley litigators nationwide to defend consumer fraud and product liability litigation targeting consumer products.
