Our story

In 1975, the founding physician of Southern Indiana Surgery, Dr. Daly Walker, left his former office and opened his own private practice in Columbus, Indiana. He fulfilled a great need and provided the community with quality general surgery service. Southern Indiana Surgery (SIS) was incorporated in 1976.


Dr. Greg Millis joined SIS as the second general surgeon, bringing innovative thoracic surgery skills and business acumen. SIS moved to a larger office at the corner of 17th Street and Gladstone.


Dr. Fredrick Shedd joined SIS. He brought with him valuable innovation and skill in breast cancer treatment and peripheral vascular surgery. Dr. C.O. Weddle merged his private practice with SIS bringing his expansive general surgery experience.


In 1994 SIS moved to the Hawcreek Medical Office Building on CRH campus. Columbus native, Dr. Michael Dorenbusch, joined SIS as the first residency-trained laparoscopic surgeon. Dr. Walker was appointed chief of staff at CRH.
