  • "Wow! Thanks to all the staff at Anderson Vet Clinic. I feel like you all truly love what you do! My kitty, Lola and I always have such a pleasant experience when we come in. Fortunately, it’s usually just for a check-up, but I would not leave Lola in anyone else’s hands but yours. Thank you for your caring commitment!"
