This 80,000 square foot proton center is located at Sibley Memorial Hospital in Washington DC. The new building was carefully placed on the only remaining campus plot – between the active construction of Sibley’s new bed tower, and the 4-story parking garage to its west.

Responding to a very constrained site, the design lifted the building above ground allowing ambulance access below and connecting the proton clinic to Sibley’s radiation oncology department with a new pedestrian bridge.

Johns Hopkins and Children’s National collaborated to create one of the few dedicated pediatric proton therapy programs in the country.

Work previously completed by John Jessen as Principal Architect with Architect-of-Record VOA Associates (now Stantec).
