After a successful career as a Wall Street medical device analyst, Mary L. Yost co-founded THE SAGE GROUP in 2002 to specialize in what was at the time an underrecognized, but widely prevalent cardiovascular problem, peripheral artery disease (PAD).

Ms. Yost’s training in economics and business at the University of California Berkeley has led to extensive research on the economic and societal costs of PAD and critical limb ischemia (CLI), as well as on costs and consequences of dysvascular amputation.

THE SAGE GROUP has become the leading research and consulting company specializing in peripheral vascular disease. Over the past 20+ years, Ms. Yost has published and lectured on chronic venous disease (CVD), PAD, CLI and amputation, as well as on PAD racial and gender disparities.
