Justin Osborne

Associate Vice President

(518) 499-04050

Justin has over 15 years of experience in the human subject research field. He began his research career on the commercial IRB side before shifting over to the local IRB world. Justin served as a non-scientific board member at the University of Cincinnati’s IRB for several years before moving back to the commercial IRB arena.

During his time at Schulman IRB (now Advarra), Justin went from IRB operations to Associate Director of Business Development, selling both IRB services and consulting services to institutions and healthcare systems. It was in this capacity that Justin realized his passion for building teams and helping others achieve their goals.

Next, Justin became the Director of Clinical Research at UC Health, overseeing all clinical research operations at the University of Cincinnati Academic Medical Center. With a talented team, Justin helped grow their research program both in number of trials and revenue. After almost five years at UC Health, and a proven track record of building teams and growing research programs, Justin was brought over to TriHealth, Inc., a community hospital system, to be their Director of Clinical Research.

With a similar goal of growing a research program, Justin spent a year and a half building a team of experienced research staff, creating new research SOPs, and implementing a new CTMS system.

Justin joined HRP Consulting in 2022 and is excited to share his experience and continue to make positive impacts on the research industry.
