Margaret Hillman focuses her practice on transactional and regulatory matters affecting health care providers. She works with her clients to achieve their business objectives while still maintaining compliance with complex health care laws and regulations.

Margaret works with clients on a wide array of transactions, with an emphasis on mergers, acquisitions, and divestitures. Her understanding of her clients’ businesses enables her to provide valuable strategic advice during all steps of a transaction.

Margaret spends much of her time providing advice to pharmacies (including infusion, specialty, retail and long-term care), durable and home medical equipment providers, revenue cycle management companies, private equity funds and physician groups. She routinely handles licensure, certification and reimbursement matters, both in the course of company operations and in connection with acquisitions. 

Before attending law school, Margaret worked in the press office at the U.S. Department of Health and Human Services, where she was able to get an insider’s view of the way health care policy is made.
