PHASE V currently maintains a core staff of 8-10 individuals. Because of its history as a University Venture Start-up, PHASE V professional staff are encouraged to maintain academic positions and are supported in independent research. The senior staff hold advanced degrees in medicine, biostatistics, epidemiology, psychology, business, program evaluation, and public health.

In addition to the regular staff, PHASE V also employs a broader network of academic consultants who participate in the scientific planning, data monitoring, analysis and evaluation committees. The research by PHASE V and consultants has resulted in major advances in the field of health outcomes research with several landmark papers among the nearly 200 publications the staff have in peer-reviewed medical and scientific journals.
