AGG Adds High-Stakes Litigator, Prominent Healthcare Attorney to its Washington, D.C., Office

WASHINGTON, D.C. – Arnall Golden Gregory (AGG) is pleased to announce that litigation attorney Matthew M. Lavin is joining the firm’s Healthcare practice in its Washington, D.C., office. Matt joins the firm as a partner with a leading healthcare litigation practice focused on provider-side reimbursement matters. As an attorney and former executive with a national network of clinical facilities, Matt has significant experience working with healthcare providers in reimbursement matters, payer relationships, audits, assignments, third-party repricing, marketing, finance, governance, government relations, regulatory compliance, and licensing. National news publications regularly cover his work, and he prides himself on taking on the significant issues that impact healthcare providers nationwide.

Joining the firm with Matt is of counsel, Aaron R. Modiano, who works routinely with Matt representing clients in healthcare litigation and other complex litigation matters. Aaron is also experienced in ERISA claims, RICO litigation, insurance unfair business practices and bad faith matters, environmental law and plaintiff’s mass tort litigation.

The addition of Matt and Aaron furthers the strategic growth of the firm’s D.C. office with the addition of new capabilities that complement AGG’s leading Healthcare practice.

“Matt and Aaron are impressive additions to the firm’s nationally-recognized Healthcare practice,” said AGG’s Washington, D.C., office administrative partner Michael E. Burke. “Our clients will appreciate Matt’s ability to successfully resolve disputes without litigation, but if and when the need arises, our clients will benefit from representation by one of the most successful healthcare litigators in the country.”

“AGG’s platform is a natural fit for our practice, and it provides us with the runway to bolster the firm’s capabilities in representing clients in provider-side reimbursement disputes and litigation. While we are resident in the D.C. office, our practice is nationwide. We look forward to serving existing and new clients in this highly contested area of law,” added Matt.
