How did the South Texas Medical Center become San Antonio's leading smart jobs engine over the last 25 years? This week’s guest is Jim Reed, the recently retired longtime chief executive of the San Antonio Medical Foundation, which led that extraordinary growth in the medical, health care and biscoences sectors. During his tenure managing the development of hundreds of acres to the growing medical center, it became home to the region's greatest concentration of hospitals, clinics, medical office complexes, and retail businesses and residential units serving and housing many of the nearly 90,000 medical center workers. Economists today say that nearly one in five gainfully employed San Antonians now work in these sectors.
