About William Ratterree

Dr. William Ratterree is originally from South Carolina and pursued an Animal and Veterinary Science degree at Clemson University. He received his doctorate in veterinary medicine at the University of Georgia in May of 2008. He completed a small animal surgery and medicine internship at Louisiana State University, School of Veterinary Medicine in July of 2009.

Dr. Ratterree stayed on at the Louisiana State University, School of Veterinary Medicine to complete a medical oncology residency in July of 2011. He received his board certification by the American College of Veterinary Internal Medicine in May of 2012. A strong passion for treating small animal oncology patients with multimodality treatments, led him to pursue a second residency in radiation oncology at Louisiana State University, School of Veterinary Medicine. He recently completed his radiation residency in July of 2013 and became boarded by the American College of Veterinary Radiology in September of 2013.

With the unique background of being boarded in both medical and radiation oncology, it allows him to formulate multimodality treatment plans specific for each patient keeping in mind quality of life and the human animal bond. Dr. Ratterree has a special interest in combining newer radiation techniques (IMRT & SRS) for his patients in combination with chemotherapy and alternative techniques. Dr. Ratterree has headed the oncology, radioiodine departments at multiple veterinary hospitals in South Florida, serves as a radiation oncology consultant for multiple clinics nationwide, is adjunct oncology faculty at Louisiana State University, School of Veterinary Medicine and in addition holds the seat of Secretary for the Collier County Veterinary Society (CCVS).

Dr. William Ratterree and Dr. Carrie Kosarek, husband and wife, are the founders of Cancer Veterinary Centers.  They saw a great need for a specialized veterinary oncology center on the west coast and in June 2016 moved here from the east coast of Florida and opened Cancer Veterinary Centers at the Naples location in the Emergency Pet Hospital. In April 2017 they opened the second location in Bonita Springs, which is a state-of-the-art cancer center to include radiation therapy.

When he is not tending to his local or distant patients, Dr. Ratterree is spending quality time with his family, his 2 cats, Luke and Leia and puppy Finn.  During football season you will find him cheering on favorite team, the Clemson Tigers!  He also aspires to get his private pilot’s license.
