Your surgeons

Dr. Peter Walsh and Dr. Celia Valverde are both board-certified veterinary surgeons. They are recognized as some of the best in their field.

Dr. Walsh and Dr. Valverde make it a little less so.

Dr. Walsh is a board-certified small animal veterinary surgeon. Specifically, Dr. Walsh is a leading dog or cat surgeon specializing in limb-spare procedures for bone tumors in dogs. In addition, he is an expert in surgical oncology and reconstructive surgery for animals.

Dr. Walsh also specializes in minimally invasive dog or cat surgery techniques. His dedication and passion for dog or cat surgery is based on his love for animals, which is why dog or cat owners choose to go to this Roseville emergency animal hospital.

The Board Certified Advantage

There are close to a hundred thousand licensed veterinarians in the United States. Only a very small fraction are board-certified. To become board-certified, a veterinarian must undergo a long and difficult process of study and testing that takes a minimum of three years to complete. The standard for certification is nothing less than excellence.
