Testimonials

Read What Our Clients Say

  • "While traveling across the country this summer, my 3 pound chihuahua had to be seen on an emergency basis. A sick dog that small can not wait long to be seen. A desk clerk from the KOA we were staying in recommended Dr. Zollars. Dr. Zollars and staff were awesome. My dog was seen immediately with great care and treatment. My fears were put to ease. So glad Dr. Zollars was recommended. Can't thank them enough. He even called later to make sure my dog was doing better and let him know if we needed anything while on the road."
