Lucky Pets See Shamrock Vets. With a love for animals and a strong commitment to providing the best veterinary care possible, Doctors Greg and Donna Shamrock thoughtfully designed their own hospital. They wanted a clean, efficient, well-rounded animal hospital where people could bring their pets and know that they would be treated well. A place where the pets and pet owners alike could feel comfortable. The happy result: an award winning veterinary care facility. The hospital design includes separate facilities for cats and dogs to help reduce the stress some pets face in visiting a veterinary clinic; an exercise yard for our canine patients; and there's even a small retail section as an added convenience to pet owners.
