Work History
Chief Medical Officer
Endovascular Health Services
New Orleans, LA
01.2021 - 01.2025
- Provided executive medical leadership for a multi-site vascular and endovascular care organization, overseeing a clinical team of 4 physicians, 3 nurse practitioners, and approximately 23 ancillary staff.
- Led the expansion of organizational service lines from dialysis access care and intermittent angiography into a full vascular care platform — including comprehensive open and endovascular PAD treatment and a complete venous disease program — increasing referral volume and patient volume at a time when the organization’s nephrology investors divested.
- Led the organization through a period of major transformation, including Corporate Integrity Agreement remediation and Chapter 11 restructuring that reduced the organization from ten centers to three; led the three surviving centers post-restructuring, stabilizing clinical and ancillary operations through a period of significant physician turnover.
- Designed and implemented new outpatient procedure selection criteria requiring documented patient complaints, abnormal exam findings, and supporting clinical testing — directly responding to the practice patterns underlying the CIA — and defended the criteria against internal pushback using evidence-based harm data.
- Served as the organization’s operational liaison to ownership and the federally appointed CIA oversight committee, coordinating with external auditors and ensuring on-time submission of required compliance deliverables.
- Rebuilt referral volume following the loss of the organization’s nephrology investor base by redirecting outreach to primary care physicians and podiatrists, including underserved areas of New Orleans.
