Jennifer Wiley, DVM, DACVIM-Oncology


Specialist, Board Certified in Veterinary Oncology

On The Job

Dr. Jennifer Wiley was the first full-time, board-certified oncologist to settle in San Antonio. At four years old, Dr. Wiley lost her mother to breast cancer, the first of many personal experiences leading to her interest in oncology. During her first year in veterinary school, she was diagnosed with a benign breast tumor, and during her residency, she was diagnosed with the BRCA1 mutation, a genetic mutation that significantly increases her risk of breast and ovarian cancer. Dr. Wiley elected prophylactic surgery to reduce her risk of cancer.

While a resident, Dr. Wiley was able to participate in a program that provided treatment for local shelter dogs with mammary tumors. Their treatment and tumors were used in many different research studies to further our knowledge of cancer in both dogs and women.

Dr. Wiley’s experiences have helped her better understand cancer itself and the emotional and physical stress that pets and their families endure. This helps to strengthen her client relationships and bring a steadfast compassion into her practice.
