Number of APEx Facility Visits: I have done five APEx facility visits so far. Two of those have been in the virtual format after the COVID-19 pandemic.

When was your first facility visit? My first facility visit was in January 2019 to a large practice in the mid-west. I did my survey with Jean Wright, MD.

Why are you an APEx Surveyor?
I am an APEx Surveyor because I truly believe APEx advances the quality and safety of patient care in today’s complex practice, given the often changing technology in radiation planning and delivery. I have realized being an active APEx Surveyor serves a dual role. In addition to critically and objectively evaluating whether a Radiation Oncology Practice (ROP) conforms to APEx Standards, I often leave the survey with something learnt from the process. Engaging in interviews with physicians, physicists and other team members from all over the United States gives me a different perspective on many aspects of radiation oncology processes. I often try to implement some of what I have learnt in my own practice that can potentially lead to more optimized solutions. This process is both intellectually engaging and fruitful from a continuous quality improvement perspective. I find this to be one of the biggest benefits to be an active APEx Surveyor and strongly value my association with APEx and its overall goals.
