If you are looking for a medical experience that matches the architectural precision and high-stakes energy of downtown Chicago, Dr. Greg S. Cohen at Northwestern Medicine is a premier destination for digestive health.
Located at 676 N St Clair St, Suite 1750, his practice sits in the heart of the "Magnificent Mile" medical district—a soaring, glass-and-steel sanctuary where Ivy League expertise meets the grit and heart of the Midwest.
The Vibe: Skyline Science
Walking into Suite 1750 feels like entering the "Control Tower" of Chicago gastroenterology. Situated just a block away from the historic Water Tower and the bustling energy of Michigan Avenue, Dr. Cohen’s office offers a panoramic approach to internal wellness.
The "Clinical Architect": Dr. Cohen is known for his structural approach to the GI tract. As a specialist at one of the nation’s top-ranked hospitals, he doesn't just treat symptoms; he deconstructs complex digestive puzzles with a level of detail that mirrors the blueprints of the skyscrapers outside his window.
The Academic Edge: Being part of the Northwestern University ecosystem means Dr. Cohen is constantly operating at the "Frontier of the Future." When you sit across from him, you aren't just getting a standard check-up—you’re getting access to the latest clinical trials and cutting-edge mucosal imaging.
The "High-Stakes" Specialist: He is a go-to for patients who need more than a generalist. Whether it's complex IBD (Inflammatory Bowel Disease) or high-level screenings, he manages the "heavy lifting" of gastroenterology.
Why the St Clair St Location is a Power Move
The Vertical Campus: 676 N St Clair is a vertical hub of medical excellence. You are in a "super-building" where world-class labs, imaging, and specialists are all connected, meaning your care is seamless and integrated.
The Commuter’s Dream: Whether you're coming from the Gold Coast or taking the "L" from the Loop, you’re steps away from the Chicago Red Line and the city’s major bus arteries.
The Post-Visit "Reset": You are minutes from the Lakefront Trail. Many patients find that the best way to digest a new health plan is with a walk toward the Pier, letting the Lake Michigan breeze clear the clinical fog.
