How We Advocate for You

With decades of clinical experience at the highest levels of hospital medicine, Clinical Advocate brings physician-level expertise directly to your loved one's bedside.

Bedside Advocacy & ICU Presence

Clinical Advocate is physically present at the bedside at Naples Community Hospital and Physicians Regional — and their associated intensive care units — ensuring your loved one receives attentive, informed care. Our background in cardiac intensive care, stroke care, and critical medicine means we understand the clinical environment and can identify concerns before they escalate.

Care Navigation & Coordination

Navigating a complex hospital system is overwhelming without clinical expertise. We coordinate directly with physicians, nurses, and specialists to ensure the care plan is appropriate, communicated clearly, and followed through — so nothing falls through the cracks.

Family Communication & Liaison

Clinical Advocate serves as the bridge between the healthcare team and your family, translating complex medical information into plain language and ensuring your questions are answered. Families should never feel left out of decisions about their loved one's care.

Cardiac, Stroke & Internal Medicine Expertise

Led by a former cardiologist with privileges in invasive cardiology and cardiac intensive care, Clinical Advocate brings specialized expertise that most patient advocates cannot offer. For patients with cardiac conditions, stroke, or complex internal medicine presentations, this depth of knowledge is invaluable.

About Clinical Advocate

Physician-Led. Patient-Focused.

Clinical Advocate was founded by Z. George Grekos, MD — a fellowship trained cardiologist and internist with more than 30 years clinical experience. Dr Grekos is a Board Certified Patient Advocate (BCPA) and brings a rare combination of clinical depth and genuine compassion to every engagement.

Our mission is straightforward: to ensure that patients and families are heard, informed, and protected at every step of the care journey — with a physician in their corner who has seen it all from the inside.

Clinical Advocate is a private-pay service designed for patients and families who want an experienced physician-advocate in their corner during the most critical moments of a hospital stay.

Hospitalized Patients & Families

When a loved one is admitted to Naples Community Hospital, Physicians Regional, or their associated ICUs — whether for a cardiac event, stroke, or complex illness — Clinical Advocate provides immediate, expert presence and advocacy throughout the stay.

Out-of-Town Families

For families who live outside Collier County or travel frequently, Clinical Advocate serves as a trusted, physician-level presence on the ground during a hospitalization.
