Norton Cancer Institute is celebrating its 20th anniversary. The original oncology practice was founded in 1994 by four oncologists, John T. Hamm, M.D., Janell Seeger, M.D., Don A. Stevens, M.D., and Thomas M. Woodcock, M.D., all of whom are still practicing at Norton Cancer Institute. The practice started as the Medical Oncology/Hematology Program, evolved into Norton Cancer Care and then Louisville Oncology. It was renamed Norton Cancer Institute in 2007 when the Norton Healthcare Board of Trustees announced an additional $100 million commitment toward fighting cancer. The institute now employs 417 staff, which includes 33 physicians, 39 nurse practitioners and two physician assistants at 12 locations.
