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.
Enrollment
Peace of Mind Starts Before a Crisis
Enrolling with Clinical Advocate before a hospitalization occurs means both the patient and their family can rest easier — knowing that a physician-advocate already understands their medical history, their values, and their wishes. When a cardiac event, stroke, or acute illness strikes, there is no scramble, no intake delay, and no learning curve. Your advocate is already briefed, already trusted, and ready to be at the bedside the moment you need them. That established advocacy relationship is one of the most meaningful protections a family can put in place — and it begins the day you enroll.

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.

Who We Serve
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.
Complex Cardiac, Stroke & Medical Cases
Patients with cardiac conditions, stroke, multi-system illness, or complex diagnoses benefit most from an advocate with deep clinical training and acute care hospital experience.
Don't Wait for a Crisis
Why Enroll Before You Need Us
Emergencies happen without warning. Families who enroll in advance arrive at the hospital with a physician-advocate already in their corner — not scrambling to find one in the middle of a crisis.
Immediate Priority Deployment
When a hospitalization occurs, your medical history is already on file. We can deploy to the bedside immediately — without wasting critical hours on intake paperwork during an emergency.
Proactive Risk Screening
Early enrollment allows us to review your current lab trends, chronic conditions such as CHF or atrial fibrillation, and complex medication regimens — catching potential care gaps before they become ER visits.
An Established Advocacy Relationship
Introducing a new advocate during a stressful ICU admission is overwhelming. Enrolling now means your advocate already knows your baseline health, your personal values, and your care preferences.
The Out-of-Town Safety Net
For seasonal residents and adult children living in another state, early enrollment provides permanent peace of mind — a trusted local medical liaison in Collier County, ready to act as your family proxy at a moment's notice.
Seamless Elective Procedure Support
If you have a planned surgery or upcoming cardiac procedure, early enrollment means an ICU-trained advocate is involved with your care plan, monitoring post-op recovery, and coordinating a safe discharge from day one.
When your loved one is hospitalized, your family shouldn't have to navigate alone.
