About Angela Diesch

Angela Diesch heads Amin Wasserman Gurnani’s Cosmetics Industry practice. Angela assists companies in complying with regulatory requirements applicable to the manufacture, marketing, and distribution of cosmetics, foods, dietary supplements, OTC drugs (including homeopathic), and medical devices. With a unique focus on the “natural” and “organic” sectors of consumer products, she advises clients at all stages of product development, including determining correct product classification and whether premarket notifications are needed.

With an in-depth understanding of her client’s businesses, Angela adeptly negotiates and drafts research and development, manufacturing, vendor, supplier, and quality agreements. She reviews product labels and marketing to ensure compliance with applicable laws and regulations and assesses claims for adequate substantiation. Angela also advises clients on developing SOPs and compliance with applicable cGMP and quality control requirements.

In addition to the regulatory side of her practice, Angela is a seasoned litigator who helps clients efficiently and effectively resolve enforcement actions and investigations initiated by the FDA, FTC, NAD, states’ attorney generals and district attorneys. Whether responding to 483s and Warning Letters, civil investigative demands, or cease and desist requests, Angela skillfully guides clients through sticky situations. She is also a results-driven, trusted advocate when clients face private litigants and class action challenges.

Angela is the Chair of NSF International’s Joint Committee on Organic Personal Care (NSF/ANSI 305) and the Chair of NSF International’s Joint Committee for Good Manufacturing Practices for Cosmetics. In that role, she helped bring the Joint Committee’s GMP auditing standard to fruition (NSF/ANSI 455-3). Angela is also the founding author of the blog CosmeticsAndThe, routinely speaks at industry conferences and seminars, and conducts educational training programs for clients’ customer service representatives and marketing teams.

Outside of law, Angela is an avid skier, whether in the backcountry or resorts. During the summer you can find her camping in her family’s ’87 Synchro Westfalia, mountain biking the single- track trails out her backdoor, or paddle boarding on the alpine lakes near her home.
