Erin also provides privacy-related compliance counseling and regulatory advice. An astute litigator, Erin also focuses on the long-term goals of her clients and provides compliance counseling.

Prior to joining the firm, Erin was a partner at an Am Law 200 firm, where she was an essential part of the firm's Biometric Privacy practice, securing landmark wins that have influenced cybersecurity and privacy legislation and litigation. Before that, she was counsel with an AmLaw 100 firm.

Erin presents and comments regularly on the topic of BIPA litigation in various panels, forums, podcasts, journals, and news outlets, having argued significant BIPA appeals to date before the Seventh Circuit Court of Appeals.
