Welcome to STL-IOIR Clinics, where we combine advanced medical expertise with compassionate, patient-centered care. Conveniently located right here in Creve Coeur, we are proud to be one of the nation's first independent, outpatient centers specializing in minimally invasive cancer and vascular treatments.

Our Mission & Vision Our mission is simple: to deliver world-class Interventional Oncology and Interventional Radiology care in a welcoming, office-based setting. We envision a healthcare landscape where patient access to minimally invasive treatments is redefined by compassion, expertise, and efficiency, allowing for faster recoveries and exceptional outcomes.

World-Class Care, Locally Delivered Founded in 2025 by Dr. Kirubahara Vaheesan—an internationally trained physician with over 30 years of experience and more than 30,000 procedures performed—STL-IOIR is built on decades of interventional leadership. Prior to founding the clinic, Dr. Vaheesan led one of the largest liver cancer programs in the country, expanding the SLU Interventional Radiology program to over 9,000 procedures annually. He has been a St. Louis Magazine's Top Doctor for the last 5 years.  He is the only interventional radiologist to receive the prestigious Naomi Judd Award from the SLU Liver Center.

 By transitioning world-class cancer and vascular care out of the traditional hospital environment and into a dedicated outpatient clinic, we offer our patients:

• Faster Access: Same-week appointments without the typical hospital wait times.

• Efficiency & Comfort: Minimally invasive care for faster recovery in a welcoming environment where you are treated like family.

• Collaborative Care: We build strong, trusted relationships with our patients and seamlessly collaborate with referring physicians.

At STL-IOIR Clinics, we are dedicated to providing the region with innovative treatments and exceptional care.
