“Membership in PNPL offers IU the ability to see the pathology field as a whole, rather than looking solely through the academic lens. The interaction with PNPL’s private practice groups allows me to understand their ‘pain points.’ Since our academic group includes community practices at the outlying hospitals, we too are feeling some of the same pain. Access to benchmarks from both academic and private practices has also been invaluable as I address issues on the academic side.”
