He subsequently joined the faculty at Baylor Scott & White Heart Hospital and is currently a clinical assistant professor at the Texas A&M College of Medicine. He enjoys the balance of urban and rural cardiovascular practice and has played an integral role in developing and expanding the cardiac catheterization program in Waxahachie to better serve a rural population while maintaining high standards of procedural quality and patient safety.

Dr. Rengarajan is an interventional cardiologist within the Baylor Scott & White network, dedicated to caring for underserved patients in Waxahachie, TX. He performs advanced endovascular and coronary interventions and is trained and certified in the interpretation of vascular, non-invasive cardiac, and cardiac CT imaging studies. His clinical practice is based at Baylor Scott & White Waxahachie, the region’s safety-net hospital serving a large rural and semi-urban population south of Dallas. With a strong commitment to equity in care, he is on the front lines of managing complex peripheral artery disease and chronic limb-threatening ischemia (CLTI), working to improve access, outcomes, and limb salvage for high-risk populations.

In 2026, Dr. Rengarajan was the recipient of the SCAI-Abbott Early Career Research Grant for his project, "Patterns of Use, Outcomes, and Disparities in Below-the-Knee Peripheral Artery Intervention Using Bioresorbable Scaffolds in Chronic Limb-Threatening Ischemia (CLTI)."
