Since graduating Hematology-Oncology fellowship from MD Anderson Cancer Center in 2012, I have worked in academics, hospital-employed positions, private practice, and locum tenens. This exposure to a diverse range of practice environments has allowed me to observe significant variabilities in practice patterns and associated clinical consequences.
