What a wonderful group of people! I don't think I will ever take my dog to any other vet. I expect people working in the veterinary field to be knowledgeable, which all the staff at VCA Thornton are. However, on a regular basis, the staff and doctors exceed any prior expectations I may have had of not only being knowledgeable, but friendly, caring and helpful. They take the time out of their day to call or check in, and they truly go the extra mile to make me and my dog feel comfortable, and informed. If you are looking for the best care for your pet, look no further. Thanks to everyone at VCA Thornton for all you do!
