Northwestern Surgical Associates (NSA) was a multispecialty surgical practice affiliated with Northwestern Memorial Hospital and Northwestern University’s Feinberg School of Medicine. Our surgeons had been in practice at and have been on the teaching faculty of Northwestern Memorial Hospital for over 50 years. NSA surgeons have repeatedly been named “Top Doctors” by Castle-Connolly, Chicago Magazine, and other professional organizations. Dr. Jeffrey S Fronza continues this tradition of excellence in his practice at Northwestern Medicine Central DuPage Hospital.

He believes that an educated and empowered patient is the best partner in this process. Patients are treated with the same respect and compassion as a member of his own family. His staff prides itself on providing professional, personalized, and prompt service. He is highly visible and intensely involved in his patient’s care from the preoperative consultation through postoperative visits.
