The Doctors

The Doctor team is responsible for each pet's medical needs. A few of their responsibilities include diagnosing, educating, establishing plans of care, prescribing medications, monitoring progress, evaluating states of health, performing anesthesiology, surgery and medical procedures and interpretation of radiographs and laboratory tests. We encourage open communication between pet owners and clinic team members. Our doctor team is at the heart of patient care and provides our leadership in delivering care to your pet.

I have always been very happy with the service and treatment we have received at Countryside. This weekend was a little disappointing, but they totally made up for it today when a vet tech came TO MY HOUSE on her way home to give my cat her medicine when they didn't have it in stock this past weekend and I couldn't bring her in myself.
