Donna Clark has over 35 years of experience advising healthcare providers on a variety of regulatory, corporate, compliance and contracting issues, with a concentration relating to the federal and state laws governing the relationships between physicians and other healthcare providers, and the entities to which they refer patients, including the federal Anti-kickback Statute and the Stark Law.

Donna advises a wide spectrum of healthcare providers, including physicians, hospitals and hospital systems, laboratories, medical device manufacturers, and pharmaceutical companies, with respect to structuring contractual and ownership relationships in compliance with laws governing referral relationships, and assists in investigations and enforcement actions when problems arise. Donna also assists healthcare providers in conducting compliance reviews of contractual and ownership relationships and in submitting self-disclosures to the federal government when such relationships are out of compliance. 

In 2021, Chambers USA noted Donna as "the go-to for Stark and Anti-kickback matters" and that clients "think very highly of her."
