Longtime TidalHealth Foundation President Denise Billing, the most successful leader of the fundraising arm of the health system, having generated more than $51 million in donations during her tenure, recently retired after 21 years of service. The funds have led to the creation of new service lines, the expansion and renovation of existing services, the purchase of cutting-edge medical technology and equipment and the creation of new patient care structures on the TidalHealth Peninsula Regional campus, including the Layfield Tower and medical campuses in Ocean Pines and Millsboro.
