Read What Our Clients Say

  • "We have been going to Companion Animal Hospital for over two years. The staff at Companion Animal Hospital is the most caring and considerate group of people who treats all of our "kids" like they are their own. We are very fortunate to be able to call them and have them there when we needed them. Awesome service!!"

  • "I found this place about 7 years ago when I was desperately calling around to see if a doctor would be willing to work on a Saturday to perform emergency surgery and save my pup. The receptionist called Dr. Lee and he agreed to drive back early from his church retreat for a 6 p.m. surgery ON A SATURDAY. We are in Orange County now, but we still make the drive so our sweet dog can see Dr. Lee for check-ups. I am forever grateful."

  • "A few years ago we had do put our 16 yr old Charlie to sleep because he had a stroke. They were so caring and compassionate. They gave us all the time we needed with him. Now it looks like we will need to take out 15 yr old yorkie :(. We won’t take her anywhere else."
