    Dr. Pennington is the BEST! Genuinely cares about the animals. We recently switched all three dogs from NEVCC. Tuesday we had to put our senior Lab down and Pennington was so awesome explaining everything and helping us make the best decision and feeling confident in that decision. Highly recommend!

    The only vet for my fur baby. Dr P is familiar with her lineage back to her grandfather and most of her local family (she is a Fidelco GSD). Awesome gentle nature with her, great staff (they even got her to and from the car for me when I was in a cast), excellent care with reasonable cost.

    This is a good place to bring your pets. We had 3 dogs all came here into there golden years and the vet was amazing when it came time to say goodbye to our babies. We now have 4 more that come here and I wouldn't ever go anywhere else. They treat you and your pets like family! Amazing place I love it!
