About

At Affiliated Physicians of Suite 118, seven independent board-certified internists share a premier address at 680 N. Lake Shore Drive in Chicago's Streeterville neighborhood. Each physician operates a fully separate practice. They share an office suite, a dedicated support team, and a commitment to thorough, relationship-driven internal medicine.

Every physician holds a faculty appointment at Northwestern University's Feinberg School of Medicine. All seven are attending physicians at Northwestern Memorial Hospital, one block away. That proximity gives patients direct access to one of the country's leading specialist networks. Each doctor keeps a limited panel, communicates directly with patients, and personally coordinates specialist referrals. The office is open Monday through Friday and offers same-day telemedicine for respiratory illness.
