Welcome to
Advanced Veterinary
Specialty Group (AVSG)

As one of the first specialty groups established in Orange County, AVSG has been setting the standard in advanced care since 1990 in dentistry, dermatology, internal medicine, oncology, surgery, and emergency/critical care.

Our approach has always been one where service is paramount and communication is based on the particular preference of the referring veterinarian. At no time will a patient be transferred from one specialty practice to another without approval, unless treatment is considered to be a medical necessity.

Our Specialty Services

AVSG is a coalition of individually owned veterinary specialty practices that offer leading edge diagnostics and treatment from Orange County’s best board-certified specialists.

AVSG After Hours

In an emergency, a pet deserves quality care—quickly. AVSG Urgent Care’s team of highly trained veterinarians is available for emergency cases on evenings and weekends when a primary veterinarian’s office is closed.

Veterinary Surgical Specialists

Our commitment to expert treatment, progressive techniques, and compassionate care make us one of the most highly-skilled, board-certified surgical teams in Southern California.

Animal Dermatology Clinic

As specialists, we stay current on new research and treatments, and are often actively involved with the research. Our dermatology practice is not limited to only small animals.

Veterinary Cancer Group

Our board-certified medical and radiation oncologists are passionately committed to improving the lives of pets with cancer by providing in-depth information and access to the latest treatments available.

Animal Dental Services

Our practice is exclusively devoted to the oral surgical and dental health of animals. Every member of our team has the credentials and expertise to perform the most complex procedures in the safest manner.

We Offer CE and Wet Lab Events for Veterinarians

Throughout the year, AVSG is host to a variety of Continuing Education and Wet Lab events for veterinarians and veterinary technicians free of charge. All of our events offer new ideas, concepts, and techniques taught by leading, experienced specialists.
