Heather Arrington is a health care attorney and Managing Member of Sullivan Stolier Schulze, LLC, where she represents hospitals, health systems, physicians, and other health care providers in regulatory, compliance, and reimbursement matters. She is certified as a Health Law Specialist by the Louisiana Board of Legal Specialization. Heather joined the firm’s Lafayette office in 2019, was appointed to its Management Committee in 2023, and became an equity Managing Member in 2025.

Heather’s practice focuses on health care regulatory compliance, including fraud and abuse matters involving the Stark Law, Anti-Kickback Statute, and False Claims Act, as well as EMTALA, HIPAA, and related operational requirements. She advises health care providers on Medicare, Medicaid, and managed care reimbursement, including Medicare audits, payment disputes, and administrative appeals involving Recovery Audit Contractors (RACs), Zone Program Integrity Contractors (ZPICs), Targeted Probe and Educate (TPE) reviews, and other government and contractor audits. She also counsels providers on hospital price transparency and other evolving regulatory requirements. Her practical understanding of health care operations allows her to help clients manage regulatory risk while maintaining efficient and compliant business practices.

In addition to her regulatory and reimbursement practice, Heather advises health care providers on physician contracting, corporate governance, and medical staff matters, including the development and revision of medical staff and governing board bylaws. Drawing on her experience defending providers in False Claims Act investigations and litigation, she also assists clients in developing and implementing compliance programs, codes of conduct, and internal policies designed to prevent and address regulatory violations.

Heather has significant experience representing Louisiana hospital service districts in the financing, development, and construction of new and renovated health care facilities. Her work includes navigating Louisiana’s capital outlay process, securing state and federal funding and appropriations, and advising on the legal, regulatory, and operational issues associated with hospital construction and expansion projects.

Heather earned her Juris Doctor and Graduate Diploma in Comparative Law from the Paul M. Hebert Law Center at Louisiana State University, where she received the Dean’s Scholar Award, the Paul M. Hebert Scholar Award, and multiple CALI Awards for Excellence. Before joining the firm, she served as an Assistant Parish Attorney at a private law firm representing Terrebonne Parish, Louisiana.

A New Orleans native, Heather attended St. Mary’s Dominican High School and graduated magna cum laude from Middle Tennessee State University with a Bachelor of Science in Music Business and Recording. While at MTSU, she studied intellectual property law and received the inaugural Chitwood Award of Excellence in Copyright Law for her proposal to reclaim author Beverly Cleary’s copyright to Ramona Quimby, Age 8 from her publisher. Her undergraduate studies sparked her interest in pursuing a legal career.
