The Mayo Clinic plans to begin construction on a $100 million expansion project at its Southside medical center campus this Summer. Expansion plans include the addition of a four story, 150,000-square-foot building that can eventually be expanded up to 15 stories. Over the next five years, Mayo plans to add 50 physicians and scientists and 250 allied health employees to support its expansion.
