Continuing to mold a new team to lead the Miami-based Jackson Health System, Chief Executive Eneida Roldan said she is bringing in a new vice president of business development and hopes to have a new chief operating officer by the end of the year. Mike Casanova, a veteran South Florida healthcare consultant, will lead the effort to bring in new business, a key because Miami-Dade's government system hopes to find new ways to bring in revenue to make up for losses from treating growing numbers of the uninsured, the Miami Herald reports. Casanova has been an executive with Surgical Park in Miami and PCA Health Plans of Florida.
