Diamond H is more than just your average veterinarian's office. We're a family. Our staff has been working alongside one another for almost a decade now while learning, laughing, and growing with each other. We treat every patient-big and small-who walks through our doors as if they were our own. At Diamond H you are more than just a client, you're family.


Diamond H Veterinary Service is a mixed animal practice serving west central Indiana and east central Illinois. We opened in 2014 and since then have become stocked with state of the art equipment to serve both our small and large animal patients.

Diamond H has the unique advantage of offering a mobile veterinary service to those unable to bring their animals to the clinic. Our fully stocked farm trucks can travel near and far to provide your animals with the care they need.

 We see appointments Monday through Saturday and have an emergency service should you ever need to use it.

As well as being here to serve our community's veterinary medical needs, Diamond H also offers grooming and boarding for our small animal patients.

At Diamond H we have a full staff devoted to caring for your animals.
