Small steps today for longer strides tomorrow

Dr. Ronni Levy is the founder and Medical Director of Wednesday Health. He is one of the few intensivists in the country to hold board certification in four specialties: Internal Medicine, Critical Care Medicine,Neurocritical Care, and Obesity Medicine. Trained at Mount Sinai, Columbia, and the University of Vermont, he has spent more than 20 years caring for critically ill patients.

‍

Much of Dr. Levy’s perspective was shaped in the ICU, where he repeatedly saw patients arrive with illnesses that had been developing for years. By the time they reached him, the window to change the course of their disease had often narrowed considerably. He became increasingly interested in those earlier years—in what might have been recognized sooner, and what could have been done differently while there was still time to change the trajectory. That question became the foundation for Wednesday Health.

‍

At Wednesday Health, Dr. Levy leads a physician-directed team of dietitians and specialists. His approach begins with knowing a patient over time rather than relying on an annual physical or isolated laboratory results. Every patient begins with a comprehensive baseline assessment, after which medical care, advanced diagnostics, nutrition, fitness, sleep, and specialty care are integrated into a plan that is reviewed and refined over time. The goal is not simply to add years, but to preserve strength, independence, and the ability to use them.

‍

Dr. Levy continues to practice critical care alongside his work at Wednesday Health. He is also an Assistant Professor at the Icahn School of Medicine at Mount Sinai, where he has taught and mentored countless medical students, residents and fellows. He has published extensively and received multiple awards for his teaching.

‍

Dr. Levy lives on Manhattan’s Upper West Side, where he built Wednesday Health to serve the community he calls home. Outside of medicine, he is an avid runner, cyclist, and swimmer. He is a Boston Marathon qualifier and a three-and-two-thirds-time Ironman finisher—the two-thirds is a story he is always happy to tell
