About
His office at 150 E. Huron Street sits adjacent to Northwestern Memorial Hospital, where he maintains an affiliation with Northwestern Medicine. He sees both cardiology and internal medicine patients, combining dual expertise into a single, continuous care relationship.
Dr. Greenfield keeps his practice intentionally small. That focus supports thorough, proactive care across cardiovascular disease management, preventive medicine, wellness, and primary care. Members reach him directly by phone or email, skip the phone tree, and schedule appointments of at least 30 minutes. He also provides telephone consultations, long-distance care, and personalized hospital advocacy, communicating directly with hospitalists at Northwestern Memorial and other facilities on his patients' behalf.
