Our clinicians

You'll know exactly who is treating you.

Every treating clinician is listed here by name, with credentials, board certifications, and licensed states — before they see a single patient. The roster grows as carefully as the panels do.

Dr. Mareen Greenway

attending: Dr. Mareen Greenway

Family Medicine · Obesity Medicine, ABOM
Licensed in 46 states and the District of Columbia · English, Spanish, Arabic

Board-certified in Family Medicine and Obesity Medicine, Dr. Greenway treats the cardiometabolic picture rather than any single number — weight, blood sugar, blood pressure, and lipids as one connected problem. She has cared for thousands of adults across the country in telehealth weight management, combining GLP-1 and other pharmacotherapy with the behavioral work that makes results durable.

She founded Attending on a simple conviction: metabolic medicine works best when the clinician actually knows the patient in front of them.

One of these clinicians will be yours.

Not a rotating pool — one clinician, assigned at the start, treating you at every visit.

For clinicians

This page is how we'd present you.

Your name, your credentials, your voice — and a panel small enough to practice the way you trained to.
