## About

The Cardiovascular Institute of the South (CIS) was established in 1983 by Dr. Craig Walker, an interventional cardiologist who built the practice into a major regional powerhouse. Headquartered in Houma, Louisiana, CIS has expanded to dozens of clinic locations primarily across Louisiana and Mississippi. The ASC entity represents the firm's deliberate push into owning the physical sites where its affiliated physicians perform cardiac catheterizations, peripheral vascular interventions, and electrophysiology procedures, shifting revenue from hospital-dependent fee schedules to a practice-owned ambulatory surgery center model. Strategy centers on physician-led vertical integration in cardiology and vascular surgery. Asset classes span healthcare real estate, private equity in ambulatory surgery centers, and operating businesses structured as majority-physician-owned joint ventures. The model targets direct investment in Medicare-certified ASCs, often co-invested with the practice's cardiologists. Geographic concentration remains in the Gulf South, with facilities in Louisiana and Mississippi. Typical deal activity involves developing de novo labs or acquiring and converting underperforming hospital outpatient departments into fully accredited vascular and cardiac catheterization suites. CIS commands a team of more than 60 cardiologists, placing it among the largest single-specialty cardiology groups in the United States. The ASC investment arm allows the practice to extract additional margin from facility fees while giving its physician partners equity in the centers where they perform procedures. Governance and deployment decisions flow through a physician-led partnership structure rather than a traditional institutional investment committee. The structural differentiator is the alignment of physician equity ownership with clinical volume: each ASC becomes a captive real estate and services asset where the operator-investors are also the sole tenants and revenue drivers. This hybrid of medical practice, real asset owner, and surgical center operator creates a closed-loop economic model rarely seen outside physician-owned specialty hospitals. Succession and partnership buy-in track clinical tenure rather than external capital raises, insulating the investment vehicle from LP redemption pressure common in fund-model healthcare platforms.
