Dr. David Childress, medical director for Physicians Regional Medical Center, describes types of services that can be provided at a 24/7 healthcare clinic should Physicians Regional provide the services. Marco Islanders will be asked in a nonbinding referendum on Aug. 14 if they would want such a clinic and support it with tax dollars. Physicians Regional will have a healtcare clinic on the island in December. It is expected that Naples Community Hospital, which has had a healthcare center on the island for 28 years, also will offer the service that would be subsidized by Marco residents. With him are Scott Campbell, left, Physicians Regional CEO and Ken Warrimer, chief financial officer.
