Regional diagnostic laboratory network running 100M+ tests annually across Arizona
Sonora Quest operates one of the nation's largest integrated laboratory systems as a joint venture between Banner Health and Quest Diagnostics, processing over 100 million diagnostic tests per year across Arizona. The hiring profile is heavily weighted toward clinical and lab staff (86 healthcare + 11 lab roles), with junior-level dominance and minimal data engineering presence—typical of a capital-intensive, volume-driven lab operation. Cost reduction and operational efficiency dominate their project roadmap, from waste reduction to route optimization, signaling pressure on margins despite scale.
Notable leadership hires: Clinical Director, Administrative Director, Lab Director, Group Lead
