Veterinary Cancer Group is one of the few oncology groups in the country to offer a private practice ACVIM Accredited Oncology Residency Program, which allows us to continue to attract highly motivated and qualified veterinarians. While meeting the stringent requirements of recognized veterinary associations, our oncologists also meet the high standards of our patients and families.
