  • Dr. Jeffrey S. Fronza, MD, FACS

    Dr. Fronza provides succinct explanations of common and complex gastrointestinal problems. He believes that a warm bedside manner sets the tone for a productive doctor/patient relationship. He enjoys working with patients to determine an individualized care plan, and then actualizing that plan during the perioperative period. As a surgeon, Dr. Fronza achieves superior functional and oncologic results by utilizing advanced surgical techniques. This intense focus on technique has resulted in Dr. Fronza being a pioneer in LINX and mesh free, natural tissue hernia repair in Illinois.

  • Dr. Mark T. Toyama, MD, FACS

    Dr. Toyama believes that a straight-forward, clear-thinking approach to surgical disease not only is the best way to treat the problem, but also is the best way to keep a patient informed. As a surgeon, Dr. Toyama weds his extensive expertise in advanced laparoscopic surgery, including the largest experience in laparoscopic hernia repairs available at Northwestern, to a belief that operations must be tailored to the particular needs of a patient.

  • Dr. Wilson H. Hartz, III, MD, FACS

    After practicing surgery for over 30 years, Dr. Hartz strongly believes that a general surgeon must understand the whole disease process and how it affects the individual patient. He is intimately involved in all aspects of a patient’s care both inside and outside the operating room. He couples this professional attitude with a warm, inviting bedside manner. As a surgeon, Dr. Hartz subscribes to the philosophy “If it looks good, it is good,” and this attention to detail in the operating room leads to excellent outcomes such as a recurrence rate of less than .5% in his personal series of inguinal hernia repairs.

  • Dr. Steven J. Stryker, MD, FACS

    Dr. Stryker treats each patient as if he/she is a member of his family. Active listening is the first step in all discussions regarding care of major gastrointestinal problems. All major elements of the patient’s care occur only with the patient’s and Dr. Stryker’s approval, and this eliminates issues of miscommunication that may occur during the care of a complex surgical condition. As a surgeon, Dr. Stryker relies on his years of experience treating complex colorectal conditions to provide his patient with the safest and most effective treatment, which assures their speedy recovery.

  • Dr. Daniel G. Davila, MD

    Dr. Davila believes that every patient deserves a customized plan of care. One size does not fill all. As a result, he dedicates time to listening to every patient before developing a more comprehensive, patient-centered care strategy. He dedicated his training to a wide range of approaches including traditional and minimally invasive techniques, including advanced laparoscopic and robotic surgery, so that multiple options are available. He enjoys working with patients and their families emphasizing an open and approachable bedside manner.
