Rochester, MN ( - A planned $5 billion expansion of the Mayo Clinic in Rochester aims to make it a world destination for health care. The Mayo Clinic says the private investment is a culmination of a three year study. However, the project requires $585 million in state money. The development initiative promises to create 35-45,000 new jobs over the next 20 years and more than $3 billion in new tax revenue to the state. Kevin Jacobsen Bio - Facebook - Twitter - E-Mail
