American Oncology Network (AON) has added Robert J. McDonald, MD, FACNM – a nationally recognized, board-certified nuclear medicine physician – as radiology medical director and in-house reading radiologist.
In this role, McDonald will support AON’s strategic expansion of radiotheranostic services throughout the network and strengthen AON’s commitment to delivering cutting-edge cancer care close to where patients live and work, according to a press release.
McDonald will serve as the primary reading radiologist for AON partner practices Florida Oncology & Hematology (FOH) in Naples and Fort Myers, and Central Georgia Cancer Care (CGCC) in Macon, “providing expert interpretations for PET and CT imaging,” the release adds. He will also perform advanced radiotheranostic therapies at the Naples and Fort Myers location, while overseeing radiology services as medical director at each practice he supports.
As AON continues to expand its radiotheranostic footprint, McDonald will play an integral role in developing physicians, supporting future program growth, and bringing advanced RLT treatment options to more AON practice sites in 2026. The Nuclear Regulatory Commission (NRC) requires new Authorized Users of radioligand therapies to complete clinical preceptorships, and part of McDonald’s position includes conducting these preceptorships on-site when needed, helping ensure safe, timely expansion of radioligand expertise across the network.
In addition, McDonald will lead clinical refinement of AON’s RLT protocols and assist in the adoption and rollout of newly FDA-approved radiotheranostic therapies – further positioning AON at the forefront of innovation in community oncology.
