Veteran Designer Specializes in Proton Beam Cancer Therapy Centers

CHICAGO, Ill.–  Jim McMillen, a healthcare architect specializing in proton beam cancer therapy centers, has joined international architecture, planning and design firm RTKL as a principal in the Chicago office. 

McMillen is a radiation technology expert with extensive and varied experience designing highly specialized imaging and radiation therapy facilities, including several proton beam cancer therapy centers.

Proton therapy is a precise form of cancer treatment that delivers significantly higher doses of radiation with greatly reduced damage to healthy tissue compared to conventional radiation therapy. McMillen has specific expertise in designing the specialized facilities that accommodate proton beam treatment for various forms of cancer.

“Jim’s expertise in designing and building technically complex proton therapy centers is vital to expanding RTKL’s significant experience in this building type. His reputation in the field of proton therapy architecture is stellar, and he is well-known to the providers of this new modality,” said Daniel C. White, AIA, RTKL Vice President and Group Practice Leader for Oncology Design.

An established industry expert, McMillen brings more than 25 years of experience to his position.  He joins RTKL’s Healthcare Practice Group from WHR Architects. McMillen holds a master’s degree in architecture from The Harvard University Graduate School of Design and a bachelor’s degree from Villanova University.
