Testimonials

  • "I love this clinic. Staff has always been kind and they are great with my dog. They always fit me in and I've never had to wait long between the waiting room and actual visit. I moved a few months ago and am sad that I have to find a new vet. Thanks for the great service for almost 5 years!"
    Kirsten Hettinger
  • "This has to be the greatest vet ever!!! Called them because my outdoor cat came home (after his 4 nights out partying) tore up really bad. They were very understanding and got me in right away. Wait time was only a few minutes and everyone was very kind. I was very worried about how much it was going to cost but I have to say that it was very reasonable."
    Monica Fisher

They have cared for all of our animals both large and small and are always very helpful during office hours and when I've had to call after hours. I would NEVER consider going elsewhere!"
