Care at the Gary C. Werths Building
The Gary C. Werths Building at Siteman Cancer Center opened for patient care in 2024. The Werths building design simplifies the experience of patients as they receive outpatient care. It offers a dedicated garage, floors dedicated by cancer type that house labs and consultation rooms, infusion services and more. Because the garage is integrated into the building, elevators are able to bring patients directly to the floor where they have an appointment. Valet services are not offered in this garage, though the ease of parking provides for a better overall experience. Patient drop-off also is available at the main entrance on the ground floor.
The Werths building is located within the Washington University Medical Campus. The WashU Medicine medical oncologists, radiation oncologists, and surgeons at the Werths building also work at Siteman’s main campus and satellite locations and collaborate regularly. These doctors practice multidisciplinary care, coordinating schedules with their colleagues so patients can see multiple physicians in one trip and have their entire treatment plan determined in one visit.
Our Werths building care team includes registered nurses with specialized training in caring for cancer patients. A research coordinator is also available to talk with patients about possible participation in clinical trials, which provide access to new medications and treatments not available at most cancer centers.






Visitors to the Werths Building can park in the attached garage. Take the elevator directly to the floor of your appointment. Each floor has designated slots for handicap parking and wheelchairs in the parking vestibuiles for visitors’ use.
There is a patient drop-off location on the ground floor.
Many of our locations offer valet services, but because the nearest garage is a part of the Werths Building, valet parking isn’t offered. Instead, use the patient drop off on the ground floor or park and take the elevator right to your specific floor.
There are several places patients can receive imaging and radiation therapy on the Washington University Medical Campus, including the Werths Building. If you are receiving imaging or radiation therapy, your care team will help you navigate where you should go on campus for your appointment.
The eighth floor of the Werths Building has radiology and imaging for patients.
In addition to that, the Center for Advanced Medicine also houses radiology services including imaging and radiation therapy. The CAM is a short walk from the Werths Building. Proton therapy takes place in its own location within the S. Lee Kling Proton Therapy Center.
