We have be using Vet Stop since 1993. Dr. Smith and Dr, McKnight are both caring and compassionate doctors. During some rough times over the years they have shown that they really care for the animals they treat. I would never trust my dogs with anyone else.

We have been using Vet Stop since 1993. The care Beau received during and after his surgery was wonderful. Dr. Smith called before the surgery to go over exactly what was to be done. We love both Dr. Smith and Dr. McKnight and wouldn't trust our dogs with anyone else.

It's hard watching our furry family members get older. But I know as they age, Vet Stop will be there to support us.

The staff is super friendly and always speedy. We never have to wait long for our appointment or results. In and out fast, but still still great quality care!!

I love the vet tech and her feedback. It was so helpful. I took all her advice. I was expecting a more welcoming experience from the vet. And more questions answered in person and more questions asked for my 1st visit as a new puppy owner
