Casillas Veterinary Hospitals

Casillas Veterinary Hospitals started out as a small facility in East Los Angeles. Over the years, we have expanded to include other communities. Our staff understands that quality pet care is extremely important and many people will travel a great distance if they have to in order to get it. That is why we expanded our service area. We offer a full line of veterinary services ranging from diagnostic exams to surgical procedures. We make getting wellness checks and vaccinations easy because with our network of offices our clients don’t have to go far from home.
