Doctors & Physicians

All 24 of our doctors, urologists, physicians, physician assistants and nurse practitioners are Board-Certified, meaning they've met the stringent educational, practice and peer review requirements put forth to achieve. Our urologists leads the entire midwest in some of our services for the number of designated Centers of Excellence. And our entire oncology department is unmatched. The best, most advanced urology care around can be found here at Associated Urological Specialists.
