John Swietlik, MD


John Swietlik, MD, is a UW Health interventional radiologist. He uses imaging to diagnose and guide treatment for a variety of conditions such as cancer or infection. Dr. Swietlik also is a clinical assistant professor in the Department of Radiology at the University of Wisconsin School of Medicine and Public Health.

As an interventional radiologist, Dr. Swietlik uses minimally invasive surgical techniques that require small incisions. Guided by X-ray, fluoroscopy (imaging that shows a continuous view of the internal body), CT scans and MRI, he performs procedures using tiny instruments inserted through small tubes into the body. This technique reduces the need for large incisions and allows patients to heal faster.

Dr. Swietlik takes every opportunity to educate his patients on their diagnosis and different treatment options. He understands that an uncertain health outcome can be scary for some people. He works hard to form a trust-based relationship with his patients to help them feel in control of their health.

Outside the clinic, Dr. Swietlik enjoys hiking and being outdoors with his family.

My hope for each one of my patients is that I've had a positive impact on their life.
