Darrell Armer
Dallas Managing Partner

I have negotiated many challenging healthcare transactions and seen parties waste a lot of time and money going back and forth with unrealistic demands, just to arrive somewhere in the middle. I approach every deal the same way – start at reasonable and stay there. By gaining an understanding of both sides’ goals and concerns, I can keep everyone focused on the real issues at stake and close the deal in the most effective, cost-efficient way possible.

An experienced dealmaker and strategic advisor for a diverse group of healthcare clients, Darrell Armer focuses his practice on structuring complex commercial transactions that not only achieve his clients’ business goals, but also minimize risk within strict regulatory frameworks. Leader of the Healthcare Transactions Practice Group, he has over 20 years of experience managing all aspects of the organization, reorganization, funding, operation and merger/acquisition of a variety of providers, including hospitals, ambulatory surgery centers, physical therapy companies, diagnostic imaging centers, medical and dental practices, and home health agencies, as well as various provider networks. He is Board Certified in Health Law by the Texas Board of Legal Specialization.

Darrell has negotiated and structured numerous mergers and acquisitions of healthcare providers on behalf of both sellers and buyers. This unique experience working on both sides of the deal helps Darrell anticipate many issues that typically arise and resolve them proactively before they can impede negotiations or break the deal altogether. Darrell also serves as outside general counsel for many of his clients, guiding them through a variety of operational and administrative matters, including Medicare/Medicaid and other third-party reimbursement and appeals, licensure issues with state boards, cyber security and related breaches, vendor contracts plus much more. 

Keeping clients out of trouble is also a substantial part of Darrell’s practice. He helps clients maintain compliance with all federal and state regulations that impact entity structuring, commercial transactions and day-to-day operations, particularly the Stark Law and the Anti-Kickback Statute, HIPAA and other privacy laws, and antitrust considerations. Darrell also plays a significant role in protecting clients when they’re facing potential civil or criminal liability in government investigations or litigation involving alleged fraud or other regulatory violations. He works hand-in-hand with the firm’s white-collar lawyers, providing valuable insight on the substantive regulatory issues involved to ensure that clients achieve the best outcome possible.
