We're pleased to announce the retirement of Mary J. Hildebrand effective November 5, 2025. Any inquiries should be directed to the Chair of Lowenstein's Data Privacy, Security, Safety & Risk Management practice, Amy Mushahwar. 

Mary J. Hildebrand founded, led and served as Chair Emeritus of the firm’s Data, Privacy & Cybersecurity Practice with the primary goal of enabling companies to launch and grow their businesses while staying in compliance with complex global regulations governing the collection and commercial use of personal information.

Access to data is critical to the growth of many kinds of businesses; however, its misuse can expose companies, executives, and employees to serious liability. Mary’s commitment to learning the intricacies of each client’s business enabled her to anticipate and mitigate risk as privacy and cyber laws quickly evolved on the state, federal, and international level. She is a recognized authority on EU and U.S. data privacy and information security laws, including the CCPA, CPRA, and the GDPR, targeted statutes such as HIPAA, GLBA, COPPA, the NYSDFS Cybersecurity Regulation, and multiple laws governing biometric data. Mary stayed ahead of the curve advising clients on new developments including recent legislation in California, Virginia and Colorado, and FTC enforcement of Regulation 5.

Cyberattacks are a fact of life across industry sectors, and Mary regularly counseled clients on breach preparedness, response and remediation strategy. When companies assembled a crisis response team, she was frequently at the top of the list. Mary leveraged her deep knowledge and experience to provide practical, spot-on advice focused on ensuring that the business continued to thrive during and after the crisis had passed.

Mary’s extensive experience in intellectual property and technology in a broad array of industries enhanced her ability to understand the data-driven challenges companies faced. For more than 30 years, clients turned to her as a trusted advisor; she has successfully guided business leaders and general counsel through difficult decisions and hundreds of sophisticated tech/data deals from concept to closing. She regularly served as lead counsel to both public and private companies in complex commercial and compliance matters, helping clients commercialize, protect, and manage their intellectual property, technology, and database assets around the world; she also counseled startups on the transactions and foundational legal structures needed to launch their businesses.

Mary was consistently recognized by Chambers USA for her successful handling of complex transactions involving significant IP and database assets. 

  • Represented Cerity Partners in merger with Ashfield Capital Partners, LLC, a San Francisco-based investment and wealth management firm that manages approximately $1.9B in assets.
